Product Description

High Precision 600-1250 mm Width Hot Dipped Zinc Coated Prepainted Galvanized Gi Strip Steel Sheet Coil

Product Description

GALVANIZED STEEL COIL

A galvanized steel coil refers to a steel coil with a layer of zinc on the surface. Galvanizing is a frequently used economical and effective anti-corrosion method. About half of the world's zinc production is used for this process. The galvanized steel coil is to prevent corrosion on the surface of the steel coil and extend its service life. A layer of metal zinc is plated on the surface of the steel coil. This galvanized steel coil is called a galvanized steel coil.

FEATURES OF GALVANIZED STEEL COILS

1. Galvanized steel coils are widely used in various environments, with long anti-corrosion life, and different anti-corrosion life in different environments.

2. Low processing cost, the anti-corrosion cost of galvanized steel coils is lower than other paint coatings.

3. Durable, in suburban environments, the standard galvanized anti-corrosion coating does not require maintenance and can be maintained for more than 50 years. 

HOT-DIP GALVANIZING LAYER FORMATION PROCESS

The formation process of the hot-dip galvanizing layer is the process of forming an iron-zinc alloy between the iron matrix and the outermost pure zinc layer. During hot-dip galvanizing, an iron-zinc alloy layer is formed on the surface of the workpiece, making the iron and the pure zinc layer tightly combined.

When the iron workpiece is immersed in molten zinc, a solid solution (body core) of zinc and α iron is first formed on the interface. This is a crystal formed by zinc atoms dissolving in the matrix metal iron in the solid state. The two metal atoms are fused, and the attraction between the atoms is relatively small.
