Description de Produit

1. Galvanized Steel Sheet Coil description
It is a steel product with a zinc-iron alloy coating on the steel surface, produced by the continuous
hot-dipping process.To achieve the required zinc coating thickness for different coating specifications
we need to pass a hot dipped strip through a variable low pressure, high volume air stream


2. Galvanized Steel Sheet Coil technical process
After cleaning and acid pickling, the steel coil is submerged in melted zinc, a chemical reaction
permanently bonds the zinc. The zinc actually permanently becomes a part of it and the successive
Layers are a mixture of zinc and iron. Galvannealed steel sheet is a special type of steel coil used
In a number of different applications within fabrication and manufacturing environments
