PPGI PPGL Corrugated Galvanized Steel Sheets Prepainted DX51D

ASTM color coated steel coil Prepainted galvanized Steel coil

The main advantage of galvanized steel is its corrosion resistance. The zinc coating serves as a barrier between the steel and the environment and will sacrifice itself in order to protect the underlying steel; Meaning the zinc will degrade much sooner than the steel itself. Additionally, it offers good processability and formability.

Hot dipped galvanized steel sheet & coil is made of carbon steel coated in zinc utilizing the hot-dip process. The end result of this process is a layer of zinc on each side of the steel sheet or coil that is tightly adhered to the steel through the formation of an iron-zinc alloy bonding layer. This bonding layer is formed by a diffusion process while the heated steel is in contact with molten zinc. Chesterfield can provide hot dipped galvanized steel sheet & coil to meet your ASTM requirements with customer-driven surface finish options.
