SGCC Galvanized Steel Coils

|

 Product Description

SGCC galvanized coil is a steel coil product that has been treated by a hot-dip galvanizing process. It uses cold-rolled steel coil as the base material, and undergoes pre-treatment processes such as pickling, degreasing, and drying, and then immerses the steel coil in molten zinc liquid for galvanizing. The surface zinc layer can effectively prevent the steel from contacting the external environment and play an anti-corrosion role. The galvanized layer can form a dense oxide film in the atmosphere, further improving the corrosion resistance of the steel. After galvanizing, the surface of the SGCC galvanized coil has the characteristics of high finish and good flatness, which can meet the surface quality requirements of different application fields. It also has good plasticity and weldability, which is convenient for processing and welding and is suitable for various processing techniques.

SGCC galvanized coil is widely used in construction, home appliances, automobiles, electronics, and other industries. It can be used to manufacture various products such as roofs, walls, refrigerators, air conditioners, auto parts, etc.

  Surface Structure

SURFACE STRUCTURE OF GALVANIZED COIL

The thickness of the galvanized layer is usually determined according to different application requirements, generally between 20-120 g/m². The greater the thickness, the better the corrosion resistance and durability of the galvanized layer. The surface structure of the galvanized coil consists of a substrate layer and a galvanized layer, which includes an outer pure zinc layer and an inner iron-zinc alloy layer. This structure gives the galvanized coil excellent corrosion resistance and surface quality and is popular in various application fields.

1. Outer pure zinc layer: The outer pure zinc layer is the first layer on the surface of the galvanized coil, which has good corrosion resistance and finish. The pure zinc layer can form a dense oxide film in the atmosphere, which plays an anti-corrosion role and gives the surface a bright appearance.

   
   

2. Substrate layer: The substrate layer is the steel base of the galvanized coil, and a cold-rolled steel coil is usually used as the substrate. After pre-treatment processes such as pickling, degreasing, and drying, the cold-rolled steel coil has a flat surface and high surface quality.

   
   

3. Galvanized layer: The galvanized layer is an important part of the galvanized coil. It is formed by immersing the substrate in molten zinc liquid for galvanizing. The galvanized layer is mainly composed of zinc and is usually divided into two layers: the outer layer is a pure zinc layer and the inner layer is an iron-zinc alloy layer.
