The characteristics and material of galvanized coil are introduced

Galvanized coil is a steel coil coated with a zinc layer to improve its corrosion resistance. In the production process, it is first necessary to immerse the steel coil in the hydrochloric acid cleaning solution containing zinc chloride, hydrofluoric acid and other chemicals to remove the oil and oxide on the surface. Then the steel coil is immersed in the molten zinc liquid, and the surface is covered with a layer of zinc by a continuous hot dip plating process to form a galvanized coil. The following Shanghai galvanized coil manufacturers to introduce the characteristics of galvanized coil and galvanized coil material.

Features of galvanized coil:

1. Excellent anti-corrosion performance: galvanized coil has excellent anti-corrosion performance, which can effectively prevent steel coil from being corroded by moisture and pollutants.

2. Good wear resistance: the surface hardness of galvanized roll is high, and it has good wear resistance.

3. Good high temperature resistance: galvanized coil has good high temperature resistance and can be used under high temperature conditions.

4. Good processing performance: galvanized coil has good processing performance, can be shear, bending, stamping and other processing according to customer needs.

5. Beautiful: the surface of the galvanized roll is coated with a layer of shiny metal zinc, which has a good look.

Galvanized coil material:

The material of galvanized coil is generally made of low carbon (such as Q195,Q215, etc.) cold rolled or hot rolled steel coil, and then made of chemical galvanizing or hot galvanizing process. Galvanized coil steel material generally has the following types:

1. SGCC steel: This steel is a hot-rolled Holley steel, because of its good paint adhesion, good formability, good corrosion resistance and other characteristics, thus creating a wide range of SGCC steel coil field.

2. DX51D steel: This steel is one of the hot-dip galvanized construction materials, often used in building roofs, wall panels, invisible skeletons and so on.

3. SPCC steel: This kind of steel is more common, is one of the essential materials in China's construction, machinery manufacturing and other industries, and its broad application makes SPCC steel coil one of the widely used materials in the market.

In short, galvanized coil with its excellent anti-corrosion performance, beautiful appearance, good processing performance and other characteristics, is widely used in building materials, home appliance manufacturing, automobile manufacturing and other industries, in the future market will continue to maintain a high demand and market share.
