Product Description

Wholesale Price  Gi Plate Strip Iron Sheet Metal Roll Prepainted Hot Dipped Galvanized Steel Strip

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.

Product Features

 Galvanized steel strip is processed by ordinary steel strip pickling, galvanizing, packaging and other processes. It is widely used because of its good anti-corrosion performance. It is mainly used to make metal products that are cold-worked and no longer galvanized. For example: metal products such as light steel keels, peach-shaped columns for guardrails, sinks, rolling doors, bridges, etc.
 

Product Process

There are many factors affecting the size of zinc flowers. When the zinc liquid composition has the conditions for the formation of zinc flowers, the following factors will affect the size of zinc flowers:

(1) Raw material: the thicker the raw material steel plate, the smaller the surface roughness, the larger the zinc flower.
(2) Cooling rate: the faster the cooling rate, the shorter the crystal growth time, the smaller the zinc flower.
(3) Number of crystal nuclei: The size of zinc flower is closely related to the number of crystal nuclei of zinc flower. When the surface of steel base is rough or the surface cleanliness is poor, the zinc flower is relatively small. Zinc grains are formed on steel base, and the more nuclei there are, the smaller the zinc flowers will be. This principle is used in the production process of small zinc flowers.
(4) Other factors (production environment, etc.
 

Product Inpection

 

 

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
