DX51D SGCC galvanized steel coil gi steel coil 0.13mm
Galvanized Steel Coil Introduction
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. We can provide hot dipped galvanized steel sheet & coil to
meet your ASTM requirements with customer-driven surface finish
options.

A zinc coating is one of the most effective and economical methods
of protecting bare steel from a corroding environment. The zinc not
only serves as a barrier between the steel and the environment, but
it will also sacrifice itself to protect the underlying steel
sheet. Sacrificial or galvanic protection occurs when two
dissimilar metals are in contact and coupled with water and oxygen.
Zinc corrodes preferentially to the iron in steel. This protection
prevents corrosion of the steel at areas not covered with zinc.
Thus, the spread of corrosion from cut edges, drill holes, etc. is
minimized.
Shandong Fulilai Steel Group is a leading supplier of galvanized
steel sheet & coil. Galvanized steel is defined as a carbon steel
sheet coated with zinc on both sides. There are two main processes
used to produce galvanized steel: continuous hot dipping and
electro-galvanizing.
The hot dipping process consists of passing the steel through a
bath of molten zinc, while the electro-galvanizing process consists
of the application of zinc through electrolytic disposition. The
result is a layer of zinc tightly adhering to the base metal
through an iron-zinc bonding layer.
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.
