Product Details
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. |
