Hot Dip Galvanized GI Steel Coil Introduction
Hot dip galvanized coil with the cold rolled steel of different strength and thickness as substrate, it is produced through applying the zinc coated on both faces by hot dip process.It is mainly produced by the continuous galvanizing process,the rolled steel plate is continuously immersed in a plating bath containing molten zinc to make a galvanized steel plate. After coming out of the bath, it is immediately heated to about 500°C to generate zinc and iron. This kind of galvanized coil has good paint adhesion and weldability.
For hot dip galvanized coil, the sheet steel is immersed in a molten zinc bath to make a sheet of zinc coated on its surface.It is mainly produced by continuous galvanizing process, that is, the rolled steel plate is continuously immersed in the zinc melting bath to make galvanized steel plate. It has corrosion resistance, painting, formability and spot welding.
Hot Dip Galvanized GI Steel Coil Product Usage
Galvanized steel coil is widly used in making pipes,cold strip-welded pipes,cold-bent shaped-steel,bicycle structures,small-sized press-pieces and household decoration goods,boating building,car producing,Corrugated roofing,food processing and medical industry,petroleum and chemical industries,etc.
Hot Dip Galvanized GI Steel Coil Product Advantage
1.Strong corrosion resistance: The zinc layer on the surface of galvanized coils has good corrosion resistance and can effectively resist wind, rain, acid rain and other external factors.
2. Long service life: After galvanizing treatment, the service life of galvanized coils can be more than twice as long as that of untreated steel, which greatly increases the service life of steel.
3.High safety: Galvanized coils not only have good corrosion resistance and aesthetics, but also have good flame retardant properties, making them widely used in the construction field.
4.Good environmental protection: During the production process of galvanized coils, a certain amount of waste gas, waste water and waste residue will be produced, but after treatment with modern technology, it can meet environmental protection standards and cause no pollution to the environment.
