Top 10 uPVC Door Manufacturers for Global Importers (Factory-Direct)
Why "uPVC Door Manufacturer" Means Four Different Things in China
Search for uPVC door manufacturers and you will find dozens of pages that look like each other, most of them ranking the same handful of names with capacity figures, export volumes and workshop counts that nobody outside the company can check. That is not a sourcing guide, it is advertising with a table of contents. So this guide does something different. It ranks the ten uPVC door manufacturers and profile houses you will actually meet once you start sending enquiries, names what each of them is really selling you, and gives you the tests that decide which of them can genuinely deliver a uPVC door to your market. Where we name a company, we describe only what is publicly verifiable about it; we publish no capacity or revenue figures for rivals or for ourselves, and we would advise you not to buy on the strength of one either.
Full disclosure before we start: this guide is published by ROPO Windows, a custom window and door manufacturer in Fuzhou, Fujian Province, China, so we are describing our own industry from inside it — and we appear on the list below. We have tried to make the tests that follow work against us just as well as for us; if a company cannot pass them, the category it belongs to is probably not the right one for your project, whoever it is.
Why the label on the website tells you almost nothing
"Manufacturer" in the Chinese fenestration industry covers at least four genuinely different businesses. There are companies that extrude PVC profiles and sell systems rather than finished doors. There are factories that fabricate doors and windows to order, welding frames and sashes from bought-in profiles. There are assembly operations that buy a welded frame and finish it locally. And there are trading companies that own no welding line at all and place your order with someone else. All four may describe themselves with the same word, and the difference between them decides your price, your quality control, your paperwork and, most importantly, who is responsible when a door arrives out of square.
The practical consequence is that the useful question is never "who is the biggest", it is "who is the right shape for this order". A profile extruder can guarantee the compound and the wall thickness, but may have no interest in fabricating a one-off door to your drawing. An assembler can be quick and cheap, and may be exactly right for a standard size in a market it already serves — and the wrong choice where the door has to be engineered against a specification and tested as an assembly. The rest of this guide is about telling those shapes apart, starting with the range of doors themselves on the custom uPVC doors range and the material family behind them on the uPVC material and colour page.
What this means for your enquiry
Most sourcing disappointments are not caused by a bad factory. They are caused by a good factory being asked to do something it does not do — a profile extruder being asked for a finished, glazed, certified door, or an assembler being asked to take responsibility for a tested assembly. The fix is cheap: state the buyer profile, the door type, the quantity, the destination market and the certification you need in the first message, and see whether the answer engages with all five or only with the price. Buyers still deciding between materials will find the door-specific walk-through in the guide to uPVC doors: styles, benefits and sourcing, and a worked example of how Chinese window and door factories present themselves is set out in the existing comparison of aluminium window manufacturers for custom projects.
The Ten uPVC Door Manufacturers, Ranked for Global Importers
The ten names below are the ones an importer actually meets — not in a listicle, but on drawings, in profile specifications and in quotations. Six of them extrude the profile systems most custom uPVC doors in the world are welded from; two are Chinese profile producers you will meet the moment a supplier quotes "Chinese profile"; one is a factory-direct door manufacturer that takes the order from your drawing and ships the finished door; and one is a European finished-product manufacturer, included as the benchmark your own specification should be measured against. These are the uPVC door manufacturers and profile houses you will shortlist, in the order we would shortlist them for a factory-direct import order.
Two things about this list before you read it. First, the order is our judgement of fit for one specific job — a uPVC door order placed factory-direct by an importer, distributor or project buyer — and it is not a ranking of size, quality or market position; a company lower down the list may be a larger business than one above it. Second, we publish no capacity, revenue, staff or export figures for any company named here, including ourselves, because figures of that kind are not checkable from outside the company. For our own business we quote only the facts a buyer can check in the documents we issue. What follows is public, verifiable description, plus the one or two things worth verifying with each.
1. ROPO Windows (China) — the factory-direct uPVC door manufacturer
ROPO is an in-house custom door factory in Fuzhou, Fujian Province, China, and the only name on this list that takes a uPVC door from a drawing through cutting, machining, galvanised steel reinforcement, fusion welding, glazing, inspection and packing under one roof and ships it under its own name. It is the profile that matches a factory-direct import order most directly, because there is no hand-off between the party that quotes the specification and the party that has to meet it: the welding lines, the reinforcement and the sealed-unit assembly are all inside one quality system.
What to verify with ROPO, or with any factory claiming this position: which operations really are in-house and which are subcontracted, and who signs the inspection report on your order. The door families these lines produce are collected on the uPVC door range, and the door-specific ranges are worth comparing side by side — the uPVC sliding door range, the uPVC hinged and French door range and the uPVC lift and slide range. A factory that lists all three and can show each being welded is a different business from one that lists them as categories only.
2. VEKA AG (Germany) — the profile system most European uPVC doors are built from
VEKA is a German extruder of PVC-U window and door profile systems, and it is one of the profile names most frequently specified in European specifications and, increasingly, in export markets that follow European practice. VEKA is a system house, not a door factory: its customers are fabricators who weld VEKA profiles into finished windows and doors, and its engineering work is in the profile geometry, the chambers, the gaskets and the surfaces rather than in the finished leaf.
What to verify: whether the doors you are quoted are actually welded from VEKA profiles or simply described as "German profile", and which profile series is being used, because series differ in chamber depth and in what they can carry across a full-height leaf. If a supplier claims to be a VEKA fabricator, ask which market's partner network that refers to. Because the profile is only one part of a door, the components fitted into it decide as much of the outcome — the hardware sets and the glazing build-up are where two doors on the same profile stop being the same product.
3. profine Group — KBE, KÖMMERLING and TROCAL (Germany)
profine was formed in 2003 by consolidating three German PVC-U profile manufacturers — KBE, KÖMMERLING and TROCAL — and produces PVC-U profiles for windows and residential doors under those three brands, alongside shutter systems and PVC sheets. For an importer it matters that the three brands are one group: a door quoted on "KÖMMERLING" and a door quoted on "TROCAL" may come from the same extrusion organisation under different market positioning, which is worth knowing before you treat them as independent options in a comparison.
What to verify: which of the three brands the profile is drawn from, whether the series is current or a legacy extrusion, and whether the same fabricator can supply a matching component years later. Those are the questions that decide whether the door can be repaired rather than replaced, and they are covered in more detail below.
4. Deceuninck (Belgium) — PVC-U systems with a strong international residential base
Deceuninck is a Belgian group that supplies PVC-U window and door profile systems and building products, with a European base and a long record of supplying residential markets internationally. Its usefulness to an importer is that it is a second established European system to compare against the German houses, frequently at a different price position, and its profiles appear widely enough that local fabricators in many markets already know the system.
What to verify: whether the specification you are being offered is a Deceuninck system or a Deceuninck-branded foil on another profile, and what the reinforcement arrangement is inside the chambers for the leaf size you need. Buyers comparing the polymer and metal options at the same time will find the decision framework in the guide to uPVC against aluminium systems.
5. REHAU (Germany) — polymer engineering behind a large window profile business
REHAU is a German polymer group that has produced PVC window profiles since the 1950s and today supplies window and door profile systems alongside a much wider polymers business. Its scale in materials engineering is the point of interest for a specifier: the profile system is supported by a materials group rather than by a single extrusion plant, which tends to show up in the consistency of compound and in the availability of technical documentation.
What to verify: the same things you would ask any system house — which series, which reinforcement, which gaskets, and what documentation travels with the profiles. Where a system is the right answer, typically for an importer planning to weld locally rather than buy finished doors, the sourcing route and the minimum quantities involved are set out in the guide to importing windows and doors from China.
6. aluplast (Germany) — profile systems for fabricators worldwide
aluplast is a German manufacturer of PVC profile systems, family-owned and oriented around supplying fabricators rather than end users, with a distribution network that reaches well beyond Germany. For an importer it is a practical comparison point: the system is widely fabricated, so a finished-door quotation built on aluplast profiles is usually reproducible by more than one plant.
What to verify: whether the plant supplying you is an established fabricator of the series you have specified, and what changes in the door when the leaf goes up in size. That second question is the one most often skipped, and it is answered by a section drawing rather than by adjectives.
7. Liniar (UK) — the trade-market profile system in Britain
Liniar is a UK-based extruder of PVC-U window and door profile systems, built around the British trade fabrication market, where the system is widely used for windows, doors and conservatory-style glazing. It is included here because it is the profile name many UK-facing importers and installers already recognise, and because it is a useful example of a market where the profile brand, not the door brand, is what the trade asks about.
What to verify: whether the door you are buying is fabricated in the UK or imported as a finished unit, since the answer changes the lead time, the warranty route and who holds the certification for the assembly. Buyers in these markets who want the finished-product view rather than the profile view will find it in the guide on specifying uPVC type, opening, glazing and certification.
8. Dalian Shide Group (China) — one of the long-established Chinese uPVC profile producers
Shide, based in Dalian, is one of the long-established Chinese producers of uPVC door and window profiles, and its name is the one that most often appears when a Chinese supplier quotes "Shide profile" or "Chinese profile" without naming a series. That phrase is worth interrogating rather than accepting, because in China the same words describe anything from a major producer's current series to an unbranded extrusion that simply resembles it.
What to verify: the profile brand and series in writing on the quotation, the wall thickness, and whether the reinforcement is galvanised steel. A door welded from a good profile and hung on poor hardware still fails, so the hardware schedule matters as much as the extrusion — the same test applies to doors supplied on custom uPVC window and door profiles from any Chinese plant.
9. Wuhu Conch Profiles and Science (China) — profile production at national scale
Conch Profiles, based in Anhui Province, is another of the Chinese producers whose uPVC window and door profiles appear in domestic and export specifications, and it is a name that comes up when a buyer asks a Chinese factory which profile it uses and is given a brand rather than a series. Its position in the market is as a profile supplier to fabricators, not as a supplier of finished doors to individual importers.
What to verify: exactly as with any profile brand in China, the series, the wall thickness and the reinforcement — and, separately, whether the plant quoting you can issue a section drawing for the door you are buying. Comparing the two material families is a separate exercise and starts from the custom window and door systems overview.
10. Internorm (Austria) — the finished-product benchmark for high-performance polymer doors
Internorm is an Austrian manufacturer of windows and doors, including uPVC and uPVC-aluminium systems, sold through a partner network in its home markets and beyond. It sells to end customers through local partners rather than to individual importers, so it is not a factory-direct source for an importer — but it is a useful benchmark, because it shows what a high-performance polymer door looks like as a finished, certified product, which is the standard your own specification should be measured against.
What to verify: not price, but configuration — the glazing build-up, the hardware specification and the certification the manufacturer publishes for the assembly. Buyers who want to see how a finished custom door is specified from the opening outwards, rather than from a catalogue, will find the working version on the uPVC door systems range, and the commercial questions that follow selection — quantities, timing, staged deliveries — in the guide to sourcing for commercial and multi-unit projects.
How to use this list
The list is not a shortlist you can buy from; it is a way of reading quotations. When a supplier sends you a price, the profile brand on it tells you which of these ten you are dealing with, and the answer changes what you should ask next. A quotation naming a European system house raises the question of which series and which hardware; a quotation naming a Chinese profile producer raises the question of the section drawing and the reinforcement; a quotation from a factory-direct door manufacturer raises the question of who signs the inspection report. In every case the last question is the same, and it is the one the eight questions below are built around.
Two further comparisons are worth making before you commit. The first is the folding and sliding alternatives to a hinged leaf, where the running gear rather than the profile decides whether the door still operates cleanly in five years — covered in the guides to bifold door systems and to lift and slide doors. The second is the window side of the same supply chain, because most importers buy both: the existing comparison of uPVC window manufacturers with factory-direct supply and the guide to uPVC window manufacturers in China for custom projects cover that ground, and the profile is the same material family on both sides of the order.
The Eight Questions That Separate a Factory From a Trading Company
Every company above can be identified in one round of questions, and these are the questions that separate uPVC door manufacturers from intermediaries. None of them require technical knowledge to evaluate — you are checking whether the answers are specific, consistent and evidenced. Ask them in writing, at enquiry stage, and read the answers as much for shape as for content.
- "Which operations are carried out in your own plant, and which are subcontracted?" A fabricating factory can name its own cutting, machining, reinforcement, welding and glazing lines. An intermediary will answer with a list of finished products instead of processes.
- "What is the profile system and the wall thickness, and can you send a section drawing?" A factory answers with a document. A broker answers with adjectives. The section drawing is also how you check for galvanised steel reinforcement inside the chambers rather than taking it on trust.
- "Which hardware set is fitted as standard for this door type?" Doors fail in daily use at the gearbox and the hinges. A supplier that names the set and explains how it is adjusted knows the product; one that says "high quality brand" does not.
- "Which certificates do you hold for this door assembly, for my market, and what is the issue date?" The answer must identify the tested configuration, not the company. Where the market requires it, an AS2047 performance report or a Miami-Dade approval applies to a tested assembly — a point explained for each market below.
- "Who signs the inspection report on my order, and can I see a redacted sample?" A factory produces an inspection document with dimensions, hardware, glazing and operation checks on it. An intermediary has to ask someone else, which is the answer you were looking for.
- "Can I order one door first?" A factory organised around custom work will accept a sample because the setup already exists. A supplier that only sells containers is telling you what kind of business it runs.
- "How is the order packed, and what is the packing documentation?" Corner protection, timber crating, film covering and a printed packing list matched to the order are the difference between a door that arrives flat and one that arrives twisted.
- "What is the warranty, what does it cover, and who administers a claim in year four?" The answer should be a document and a process, and it should name the same legal entity that appears on your contract and your invoice.
Three of these answers can be checked before you send anything. The uPVC door product range a supplier publishes should show engineered configurations rather than a photo gallery; the windows and doors factory profile should describe real production steps rather than marketing categories; and the quality control and certification page should publish certificates that identify a product line. The technical documents an importer normally assembles — sections, glass options, hardware schedules and certificates — should be downloadable in one place from the download library, and the production and inspection stages should be visible in the factory production videos. If a supplier cannot show any of the three, the profile question is answered for you. The same sequence, applied specifically to uPVC windows, is set out in the guide to choosing and verifying a manufacturer, and the commercial questions that follow selection — quantities, timing, staged deliveries — are covered in the guide to sourcing for commercial and multi-unit projects.
uPVC Door Certification and What Changes by Market
Certification is the fastest way to identify which of the ten names you are actually dealing with, because a fabricating factory holds documents in its own name and can produce them the same day, while an intermediary has to request them. More usefully, certification is also the point at which a specification stops being a preference and becomes a set of tested constraints: once an approval is in play, the frame, the glass, the hardware and the fixing detail are a tested assembly rather than a menu. The documents that back the claims, per product line, are collected on the quality and certification page, and the door types those documents have to cover are listed across the uPVC door assemblies range.
Australia and New Zealand: AS2047, NZS4211 and the AS/NZS glazing standards
For Australia and New Zealand the specification is generally driven by performance under wind and water load, with a separate standard governing the security performance of the window or door itself. Because those two requirements test different things, an assembly can satisfy one and not the other, and the difference between them — and how compliance is demonstrated — is set out in the guide to AS2047 and NZS4211 for aluminium and uPVC systems. In these markets the uPVC door assembly is also required to satisfy the glazing standards for safety glass, human impact and insulating units, which is why a compliant door is documented as a set of components rather than as a frame with glass in it. Bushfire-prone sites add a further layer, and the practical implications for specification are set out in the site's guide to windows and doors in bushfire prone areas; the wider picture of how suppliers in this market present standards and ratings is covered in the existing guide to suppliers, standards and ratings in Australia.
North America: NFRC ratings, ENERGY STAR and Miami-Dade approval
The North American model rates performance per product configuration rather than per material, expresses energy performance through a programme threshold, and — in wind-borne debris regions — requires the assembly to be approved as a tested set including its glazing and hardware. Those are three different documents, usually held by the same supplier. The framework that ties them together is explained in the guide to certification for the United States and Canada, and the route for coastal and hurricane-exposed areas — where the approval is an entry condition rather than an upgrade — in the guide to Miami-Dade approved impact windows.
Europe, the Middle East and other markets
Where a market works to a European-style framework the relevant mark is CE, applied to the product family and the configuration that was assessed. Other destinations — the Middle East, South America, South-East Asia — frequently work to a project specification that names a performance requirement rather than a fixed product standard, in which case the document that matters is the test report for the assembly you are actually buying, in the size and configuration you are buying it in. The useful habit in any market is to name the approval in the first enquiry rather than after the quotation, so that the specification is written against the right standard from the start. Buyers comparing the two material families can start from the uPVC material reference for the polymer side and the aluminium systems page for the metal side.
The three documents to request, in any market
Three documents answer three different questions and are worth requesting at quotation stage. A written specification should name the profile system, the reinforcement, the glazing build-up per opening and the hardware set, so that what is being certified is unambiguous. Test reports and compliance certificates should identify the product line and the tested configuration, because an approval covers the assembly as tested rather than the family it belongs to. Both should then be backed by a warranty that states its term and its scope, published per product on the window and door warranty list. Where an order is placed through a platform that holds payment against delivery and documents the agreement, that protection is a further safeguard on a first order and is described under Trade Assurance for window and door orders.
About ROPO Windows
ROPO is a custom windows and doors manufacturer based in Fuzhou, Fujian Province, China, with 16 years of experience in bespoke window and door production. The factory ships to clients in more than 100 countries and regions and works to a simple operating philosophy that the whole team follows: "Do what we say we are gonna do." In a market where uPVC door manufacturers are often described with adjectives rather than documents, that sentence is the one we would rather be judged on.
ROPO is the first name on the list above, and it is there for one reason: it is an in-house custom uPVC door manufacturer that takes a uPVC door from a drawing through cutting, machining, galvanised steel reinforcement, fusion welding, glazing and inspection under one roof, and ships it under its own name. Frames and sashes are produced in-house rather than bought in, which keeps the operations that decide how a door performs under the factory's own control rather than distributed across subcontractors. Products are manufactured and tested to recognised standards including AS2047, AS/NZS2208, AS1288 and AS4666, and NZS4211 for Australia and New Zealand, with NFRC, AAMA, NAMI, Miami-Dade and CE certification for North American and other markets; the company is also a member of the Australian Glass and Window Association. A minimum order quantity of one piece means a single sample door can be ordered to inspect the profile, the reinforcement, the hardware and the glazing first-hand before a project commitment, and every order is backed by a 10-year warranty. Company and plant details are on the ROPO Windows company profile and the windows and doors production facility, the door families are collected on the custom uPVC door range, the material family is set out on the uPVC material and colour page, and the questions worth putting to any factory before an order are collected in the guide to verifying a window and door manufacturer.
Custom Production Process
The reason the verification questions above work is that a uPVC door factory has a physical sequence, and you can ask to see each stage of it. Every order at ROPO follows the same workflow, whether it is a single sample door or a project release, and each stage produces a document the buyer can hold on to:
- Design confirmation - door type, opening direction, opening configuration, profile system, colour and finish, glazing build-up, hardware and handing are reviewed and confirmed in writing before production begins. This is the stage where a custom uPVC door stops being a description and becomes a drawing, and where the aperture dimensioning the drawing depends on is settled rather than assumed.
- Profile preparation - frames and sashes are cut and machined to the approved dimensions, galvanised steel reinforcement is inserted into the profile chambers, and corners are fusion welded and cleaned so that the joint is continuous and airtight. Welding, not mechanical fixing, is what makes a uPVC frame monolithic, and this is the stage that determines whether the frame stays square and rigid once it is hung.
- Hardware and glazing - gearboxes, hinges or friction stays, handles, the specified sealed units and the threshold detail are fitted and sealed by trained operators, and every leaf is set so that it closes onto its gasket evenly across its full height. Because the hardware travels with the system it was designed for, the door arrives as the assembly that was specified rather than as a frame plus whatever was available.
- Five-step quality control - an order review before any material is cut, incoming inspection of profiles, reinforcement, glass and hardware, semi-finished inspection at the stage where dimensions can still be corrected, finished product inspection with every leaf operated and its seals and hardware verified, and a final inspection report issued before packing. For an importer, the last two are the ones to ask for, and the assembly and testing stages are shown running in the factory production and inspection videos.
- Documents and traceability - test reports, compliance certificates and packing documentation are prepared for each order, and every unit is barcoded so that its production record can be traced from installation back to the batch it was built in. That record is what makes it possible to supply a matching component years later rather than a visually similar one, and the test evidence is collected on the certification documents for each product line.
Because the specification is agreed in writing and held against the order, a project that has to be staged — one elevation now, one later, with the same finish and the same hardware across both — can be produced as a single specification released in parts, and the scheduling and documentation questions that go with that are covered in the guide to commercial and multi-unit projects. Buyers who want to understand what is inside the frame they are approving, and how a uPVC door is specified from the opening outwards, will find the component-by-component explanation in the guide to specifying uPVC type, opening, glazing and certification, while the full door families this process is applied to are listed across the uPVC door ranges.
Packaging and Shipping
A door that is damaged in transit has no specification at all, and the parts of a uPVC door that are most easily damaged are exactly the parts the specification cannot protect: welded frame corners, glazing edges and loose hardware. Units ship from Fuzhou to clients in more than 100 countries and regions, so packaging is treated as part of the product rather than a cost to be minimised. Frames are protected with sturdy timber crating and corner guards, glass surfaces are covered with protective film, and loose hardware is packed separately where necessary so that it cannot damage a unit in transit. The film is worth leaving in place until installation, because it protects the frame and the glass through the dirtiest stage of any building project, after which it strips away cleanly — the same principle that applies to the hardware and accessories travelling with the order. The approach is set out in full in the site's windows and doors packaging guide.
ROPO ships from the ports of Fuzhou and Xiamen by sea, with full container and shared LCL options, so a single sample door and a project release can both be shipped without waiting to fill a container — which is what makes a sample-first approach practical when you still have a specification to test against a real opening, and what makes mixed orders of hinged, sliding and lift-and-slide doors workable in one consignment. Lead time is managed through a system rather than a promise: profile and hardware inventory is kept in stock and orders are followed up at every production stage, so the schedule can be confirmed at any point rather than guessed. The installation detail that decides whether a uPVC door performs as specified once it lands — fixing positions, packing and sealing — is collected on the window and door installation page, with the corresponding remedy guidance on the correction page, and completed work is documented in the project case studies. The door families these orders are built from are listed across the uPVC door families, from hinged entrance leaves to sliding and lift-and-slide systems.
On payment, the two structures that matter to a first-time importer are the terms attached to the order and the protection attached to the transaction. Terms should be agreed with the same entity that signs the inspection report; on a first order, placing it through a platform that holds payment against delivery and documents the agreement adds a layer of security that is worth more than a small price difference. That structure is described under Trade Assurance for a first order, the wider commercial picture — minimum quantities, timing, shipping and payment — is covered in the guide to how to import windows and doors from China, and the sequence for testing a supplier before committing is set out in the guide to testing a supplier before you commit. A free price for a specific opening can be requested through the quick selection and quotation form, or by sending your door inquiry directly.
uPVC Door Sourcing FAQ
These are the questions importers actually send us, and they apply to any of the uPVC door manufacturers you shortlist rather than only to us. The answers below are the working version, not the brochure version.
How do I tell whether a "uPVC door manufacturer" in China is a real factory?
Ask the eight questions above in writing and check three of the answers yourself: whether the factory page describes production processes rather than product categories, whether certificates are published per product line, and whether a section drawing and a sample inspection report can be produced. A welding factory answers all three from its own records; an intermediary has to go and ask someone else, and that gap is visible in the reply. The same test applied line by line to a uPVC window plant is set out in the guide to choosing and verifying a uPVC manufacturer.
What drives the price of a custom uPVC door?
Almost everything that moves a uPVC door price is a specification decision rather than a supplier's margin: the profile system and its wall thickness, the number of chambers, whether the frame is steel-reinforced, the size and configuration of the leaf, the glazing build-up, the hardware set and the finish. That is why three quotes for the same nominal opening can legitimately differ, and why the breakdown is worth understanding before comparing numbers — the structure of a custom window and door price is explained in the guide to how custom prices are built up, with the item-by-item cost factors on the prices explained page.
What glazing should a custom uPVC door have?
The answer depends on the elevation, the climate and the market rather than on preference. Sealed double or triple units carry the thermal and acoustic performance; laminated glass adds retention when the requirement is that the opening stays closed; toughened glass changes how a pane breaks where people walk past it, and where the door is full-height or near a floor level it is normally not optional. The options with their trade-offs are collected on the glass and glazing options page, and the layered approach where glass, hardware and screens are specified together is set out in the guide to how window and door security is specified.
Can I order a single uPVC door before committing to a project?
Yes, where the manufacturer is organised around custom work. A minimum order quantity of one piece exists precisely so that a buyer can inspect the welded corner, the reinforcement, the hardware and the sealed unit on a real door before a project release, and the acceptance points that make a sample useful — what to measure, what to operate, what to photograph — are covered in the guide to sample orders and first orders. Measuring the opening correctly is the other half of a successful first order, and the difference between hole size, frame size and installation gap is explained in the guide to measuring window and door openings.
uPVC or aluminium for doors — and does the supplier matter more than the material?
The material question is decided by span, sightlines, climate and budget rather than by quality, and the comparison is set out in the guide to uPVC doors against aluminium, with the polymer side of the range described on the uPVC material and colour page and the door types themselves covered on the custom uPVC doors range. What matters more than the material is the profile of supplier behind it: an in-house fabricator can be held to the specification whatever the material, while an intermediary cannot be held to it in either. Buyers who want to compare door configurations across both families can start from the custom window and door systems overview, and the cleaning and hardware-care routine that keeps either material performing is set out in the site's guide on maintaining uPVC windows and doors.
Request a uPVC Door Quote
To move from research to a quotation, send the door type and size per opening, the opening direction and configuration, the destination market and the certification you need, the colour and finish, the hardware level, the quantity, and the port. That is enough to come back with a priced, like-for-like quotation and the supporting documents, and it also allows a supplier to flag where a cheaper option would perform identically and where it would not — which is the one piece of advice a ranking page can never give you.
Start with the quick selection and quotation form for a free price, send your window and door inquiry or contact the ROPO export team directly, review completed work in the custom windows and doors project case studies, and browse the door families on the custom uPVC door range, the door collection and the custom door range. Distributors and dealers evaluating a long-term supply relationship will find the programme questions on the dealer and wholesaler page, homeowners the step-by-step route on the homeowner guide, and specifiers the drawing and scheduling questions on the builder and specifier page. Door assembly and installation walk-throughs are collected in the uPVC videos collection, aluminium systems in the aluminium videos collection, local support in Australia is described on the Australian local partners page, and further sourcing and technical guides are published on the ROPO windows and doors blog.
