How to Check Galvanized Steel Coil - A Quality Control Manual

Inspection of galvanized steel coils is vital so as to ensure quality and performance. Important factors to look out for during inspections include surface deficiency through visual assessment, checking if the coating is of uniform thickness and ensuring the coating meets the relevant standard requirements for the industry. Devices such as the magnetic thickness gauges can be used to assess the degree of zinc coating but compliance with the ASTM specification also guarantees that the coils are to the world standards. If all these inspection techniques are adhered to, you can have a better basis to gauge the quality of galvanized steel coils and therefore when you purchasing makes more sense.
