What is Galvanized Steel Coil(GI)?
Which is one kind of basic material for Galvanized metal roofing.
Galvanized Steel is one of the hot-selling steel products in the
world.According to the processing method, people normally divide
the galvanized steel into two different type:
1.Hot-dip Galvanized steel
Hot-dip Galvanized steel is to immerse a thin steel plate in molten
zinc,then a layer of zinc is attached to the surface of the steel.
It is one kind of popular anti-corrosion method and can provide a
long service life of metal materials.
Hot dipped galvanized steel coil, the thin steel plate is immersed
in the molten zinc tank, so that a thin steel plate with a
layer of zinc is adhered to the surface. At present, the continuous
galvanizing process is mainly used for production, that is,
the rolled steel sheet is continuously immersed in a galvanized
bath with molten zinc to make a galvanized steel sheet;
alloyed galvanized steel sheet. This kind of steel plate is also
manufactured by hot dipping method, but immediately after
leaving the tank, it is heated to about 500°C to form an alloy film
of zinc and iron. This galvanized coil has good paint
adhesion and weldability.
2.Electro-galvanized steel
Electro-galvanizing is a process of applying a layer of zinc to
steel through electroplating, with a saline anode and steel
conductor. It is able to enhance the corrosion and heat resistance
of steel. Also, it makes steel sheets more good-looking.
