Product Description
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.
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.
For galvanized steel coils, the steel sheet 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 a plating tank with zinc melted to make galvanized steel plate; alloyed galvanized steel plate. This kind of steel plate is also manufactured by hot dip method, but immediately after being out of the tank, it is heated to about 500 ºC to form an alloy coating of zinc and iron.This galvanized coil has good paint adhesion and weldability.

Galvanized steel coil inspection
1. Size and shape measurement items: allowable deviation of thickness, width, length, unevenness, out of square degree and sickle bend.
2. Chemical composition test items: carbon content, sulfur content, manganese content, silicon content, phosphorus content, titanium content, aluminum content, niobium content, vanadium content, etc.
3. Physical performance test items: yield strength, tensile strength, elongation after breaking, R value, N value, tensile strain mark, baking hardening value, coating adhesion, coating weight, coating surface structure, surface quality, adhesion and corrosion resistance.
4. Environmental performance evaluation test items: lead content, content, cadmium content and hexavalent chromium content.
5, galvanized sheet brand identification
Galvanized steel coil can be widely used in different applications after further processing,including:
1.Galvanized steel Coil for Construction
They are often used as roofing,interior and exterior wall panels,the surface sheet of the balcony,ceiling,partitioning walls,windows and doors,gutter,barn,sound insulation wall,etc.
2.Galvanized steel Coil for Home using
GI coil is widely applied to home appliances,such as the base of washing machines, water heaters, refrigerators, microwave ovens,etc.
3.Galvanized steel Coil in Transporation Industry
It is mainly used as decorative panels of cars, deck of trains or ships, containers, road signs, etc.
4. Galvanized steel coil in other uses which like wardrobe,locker,radiator,lampshade,table,bed,bookcase,shelf,post,telecommunication cable and highway guardrail etc
Wooden tray, iron wrapper, waterproof paper.The steel strips supplied according to the standard are usually applied with common rustproof oil film, which can be swept away with alkali solution. The supplier guarantees that the oiled products will be free from rust under normal packing, transportation, loading and storage conditions within 6 Months, the approved delivery date.
