Galvanized Steel Coils:
Hot dipped galvanised steel coils are a popular and versatile product used in the construction, manufacturing, and industrial sectors. Produced by immersing steel coils in molten zinc, this process creates a protective layer that increases the durability and longevity of the steel.
As a leading factory for hot dipped galvanized steel coils, we are committed to producing high-quality products that meet the needs and expectations of our customers. Our state-of-the-art manufacturing facilities and experienced team allow us to consistently deliver superior products at competitive prices.
Hot-dip galvanizing (galvanizing) is also called hot-dip galvanizing and hot-dip galvanizing: it is an effective method of metal anti-corrosion and is mainly used for metal structural facilities in various industries. It is to immerse the rust-removed steel parts into molten zinc liquid at about 500°C, so that the zinc layer is attached to the surface of the steel components, thereby achieving the purpose of anti-corrosion. Hot-dip galvanizing was developed from the older hot-dip method. Since France applied hot-dip galvanizing to industry in 1836, it has a history of more than 170 years. In the past thirty years, with the rapid development of cold-rolled strip steel, the hot-dip galvanizing industry has developed on a large scale.

Hot dip galvanizing process:
■
Degreasing, water washing, rust removal, water washing, plating aid, drying, hot dip galvanizing, water cooling, inspection and trimming
■
The first 5 items are pre-plating treatments to ensure that there is no oil or rust on the surface of the black parts, and a solvent protective film is formed.
■
Hot dip galvanizing process:
The solvent reaction further cleans and activates the iron surface. The iron-zinc reaction generates an iron-zinc (intermetallic compound) alloy layer. The iron surface is heated above the melting point of zinc, making the iron surface a flowable liquid zinc.
