When it comes to surface treatments for aluminium components like windows, two of the most common finishes are powder coating and anodizing. Both enhance durability and aesthetics—but they differ significantly in process, performance, and appearance. If you’re unsure which finish has been applied to your aluminium window, TCR Engineering can help.


To confirm whether the surface is anodized or powder coated, TCR will conduct:

  • Anodizing Test – This determines the presence and nature of the anodized layer by evaluating its electrochemical properties.

  • Coating Thickness Test – This measures the thickness of the surface coating, which often differs between anodized and powder-coated surfaces.


These tests help distinguish between the two treatments by identifying key differences in layer structure, hardness, and electrical properties.


Turnaround Time:4–5 working days after receiving the sample and payment at our lab.


Sample Size Required:25 mm wide × full thickness × 50 mm long


Whether for quality control, supplier verification, or dispute resolution, trust TCR’s precise and reliable testing methods to confirm the surface treatment of your aluminium products.
