Product Description

Hot-Dipped Galvanized Steel Strip in Coil (GI) is manufactured by feeding full-hard steel sheets—after they've been acid-washed and rolled—into a molten zinc bath, resulting in a zinc layer applied to their surface. Thanks to the natural traits of zinc, this product offers strong corrosion resistance, good paint adhesion, and impressive workability. Galvanized strips are products further processed from galvanized coils, and their varied dimensions can meet more differentiated needs.
