🟧 Introduction

Buying aluminum profiles may seem straightforward, but many engineers and contractors fall into common mistakes that result in project delays, poor performance, or unexpected costs.
This guide highlights the top 10 mistakes and how to avoid them.

1. Not specifying the exact thickness

Many buyers only check price per meter and ignore the actual profile thickness.

Solution:
Always measure using a micrometer and ensure it matches project requirements.

2. Ignoring ISO 7599 anodizing standards

Some suppliers focus on color only, not oxide layer thickness.

Solution:
Request certification (AA10, AA15, AA20, AA25).

3. Buying from non-specialized distributors

Different suppliers = inconsistent quality.

Solution:
Buy directly from a factory for reliable uniformity and better prices.

4. Not checking profile straightness

Warpage creates issues during installation.

Solution:
Roll the profile on a flat surface to test alignment.

5. Not checking color quality

Low-quality anodizing fades or stains quickly.

Solution:
Check under strong lighting + use simple acid spot tests.

6. Mismatched dimensions

Some profiles arrive with incorrect tolerances.

Solution:
Verify dimensions with calipers before receiving the shipment.

7. Ordering without sample approval

Pictures are not enough.

Solution:
Request physical samples before large quantities.

8. Ignoring alloy type

Low-quality alloys cannot handle stress.

Solution:
For serious projects use 6063 or 6063-T5.

9. Skipping final inspection

Scratches or dents are common in poorly stored profiles.

Solution:
Inspect every batch before loading.

10. Choosing based on price alone

Cheaper material usually means:
 – Lower thickness
 – Poor anodizing
 – Weak alloy
 – Bad color consistency

Solution:
Choose a qualified factory offering stable quality and technical support.
