How to detect whether powder coating is on GI vs CRCA?



Q. During assembly we found a mix-up issue. Please give a visual detection standard or is there any instrument for the same.

A. Hi Abhijeet. If there was a way to detect visually, buyers would insist on the process being improved so there wasn't :-)

A simple magnetic pull tester can reveal the combined thickness of non-magnetic galvanized and powder coated finishes, so if the galvanizing is quite thick and the powder coating is quite thin, perhaps it can differentiate. Beyond that you would need a more expensive non-destructive test such as x-ray fluorescence or beta backscatter.

Luck & Regards,
