ASTM 653 Prepainted PPGL DX51D DX52D SGCC Galvanized Steel Sheet Coil

Description

ASTM **3 Prepainted PPGL DX*1D DX*2D SGCC Galvanized Steel Sheet Coil

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.
