Choosing a Custom Aluminium Windows Manufacturer: What 95% of Buyers Overlook
When builders or developers search for custom aluminium windows, most of them compare only price and delivery time.
From our factory experience, this is a very common mistake.
I can say honestly, 95% of buyers overlook some very important point when choosing a custom aluminium windows manufacturer.
As a China-based aluminium window factory with certification for Australia, New Zealand, USA and Canada, we have seen many successful projects — and also some failed cooperation because buyers did not check deeply enough.
In this article, I will share what most people ignore, and how to choose correct partner for long-term business.
Certification Is Not Just Paper
Many suppliers say they can do custom made aluminium windows, but do they really have certification for your market?
For example:
| Australia | AS2047 |
| New Zealand | NZS standard |
| USA | NFRC |
| Canada | CSA |
We already hold certifications for these regions. Honestly speaking, this already exceeds 95% of Chinese factories.
For projects in custom aluminium windows melbourne or custom aluminium windows sydney, certification is not optional — it is mandatory.
Without compliance, your project risk becomes very high.
Customization Depth (Not Only Size)
Many buyers think customization means only change width and height.
But real custom size aluminium windows include:
1, Thermal break width adjustment
2, Glass configuration design
3, Frame thickness selection
4, Wind load calculation
5, Acoustic performance matching
6, Hardware system upgrade
For example, in a Sydney coastal villa project, builder required strong wind resistance and slim design.
We provided:
Reinforced frame structure
Double glazed Low-E glass
Salt-resistant surface treatment
This is real customization, not just changing dimension.
