What is a galvanized steel coil?
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.
Is galvanized better than carbon steel?
Galvanized steel is created by dipping standard steel into molten zinc by a process
called hot dipping. The layer of zinc serves as a protectant from
corrosion. The protectant makes galvanized steel the best option,
over untreated carbon steel, for worksites that are exposed to acid
rain, road salt, and sea water.
Hot dip galvanized steel plate DC51D,also named as hot dip galvanized steel sheet DC51D+Z and hot dip zinc coated steel plate and coil
DC51D+ZF.Under Q/BQB 420 steel standard,there are DC51D+Z,DC51D+ZF
which is for bending and profiling quality,DC52D+Z,DC52+ZF which is
for drawing quality,DC53+Z,DC53+ZF which is for deep drawing
quality,DC54D+Z,DC54D+ZF which is for special deep drawing
quality,DC56D+Z,DC56D+ZF which is for extra deep drawing quality.
DX51D stands for galvanized steel sheet. The first D means flat
steel for cold forming. The X means the rolling state is
indefinite. 51 is the series number of the steel. The second D
means hot dipped galvanized.

Galvanized steel coil is the steel coil with hot dipped surface coating such as zinc.
According to steel material’s advantages of strength, durability
and toughness, also according to advantage of protection as zinc
plating against to rust and corrosion, galvanized steel coils
widely are applied to more industries.
