Chromated oiled G40 G90 ASTM A653 JIS G3302 Hot Dipped Galvanized Steel Strip

Galvanized steel is a hot-dipped coated metal that provides customers with better resistance to corrosive environments. To create galvanized steel, cold rolled steel is submerged into a molten zinc bath, known as the hot-dip process (galvanization can also be achieved through continuous galvanizing). When the material is removed from the zinc bath and cooled a reaction to the oxygen in the air occurs. The reaction causes the zinc coating to become part of the steel creating the well-recognized spangled finish.
