Galvanized Steel Coil Introduction
Galvanizing, or galvanization, is a manufacturing process where a
coating of zinc is applied to steel or iron to offer protection and
prevent rusting. There are several galvanizing processes available,
but the most commonly offered and used method is called hot-dip
galvanizing.
Galvanized steel is among the most popular steel types because of
its extended durability, having the strength and formability of
steel plus the corrosion protection of the zinc-iron coating. The
zinc protects the base metal by acting as a barrier to corrosive
elements, and the sacrificial nature of the coating results in a
long-lasting and high-quality steel product.
Advantages of Galvanized Steel
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.
