How to distinguish the epoxy coating quality of Security screen

Powder coating is one of the most important factor that decides the quality of the security mesh screen. Then how to distinguish it?

1. Baking identification

There is not a lot of smoke produced by good powder during the baking process, while poor powder have a lot of smoke during the baking process.
