galvanneal process
Quick Summary
The galvanneal process involves coating iron or steel with an alloy of iron and zinc. This is achieved by heating a surface that has already been galvanized with zinc. The resulting alloy coating offers improved weldability, abrasion resistance, and paintability compared to standard galvanizing.12
Galvanizing, in general, is a method to protect iron or steel from rusting by applying a zinc coating. This can be done through hot-dip processes or electrolytic deposition. The galvanneal process is a variation of hot-dip galvanizing where the strip is heated after coating to create a heavy iron-zinc layer.31
