Effective Corrosion Protection – The zinc coating on the steel surface forms a durable barrier that prevents rust and extends the life of the steel.
Enhanced Durability and Longevity – Galvanized sheets help maintain structural integrity over time, reducing maintenance and replacement needs.
Wide Range of Applications – Suitable for multiple industries including construction, automotive, agriculture, animal husbandry, fishery, light industry, and commerce.
Versatile and Reliable Material – Combines the strength of steel with protective zinc coating, making it suitable for both structural and functional applications across diverse environments.
Product Description
Galvanized sheet refers to a layer of metal zinc coated on the surface of the steel sheet, which is called galvanized sheet. Galvanized steel sheets are often used to prevent corrosion on the surface of steel sheets and prolong their service life. Mainly used in construction, light industry, automobile, agriculture, animal husbandry, fishery, commerce and other industries.

Galvanized steel sheets can be divided into the following categories according to production and processing methods:
①Hot-dip galvanized steel sheet. Dip the thin steel plate into the molten zinc tank to make the thin steel plate with a layer of zinc adhered to its surface. At present, the continuous galvanizing process is mainly used for production, that is, the coiled steel plate is continuously immersed in a galvanizing tank with molten zinc to make a galvanized steel plate;
②Alloyed galvanized steel plate. This kind of steel panel is also made by hot dip method, but it is heated to about 500℃ immediately after coming out of the tank, so that it can form an alloy film of zinc and iron. This galvanized sheet has good paint adhesion and weldability;
③Electro-galvanized steel plate. The galvanized steel panel manufactured by electroplating has good processability. However, the coating is thinner and its corrosion resistance is not as good as that of hot-dip galvanized panels;
④Single-sided galvanized steel and double-sided galvanized steel. Single-sided galvanized steel sheet, that is, a product that is galvanized on only one side. In terms of welding, painting, anti-rust treatment, processing, etc., it has better adaptability than double-sided galvanized sheet. In order to overcome the shortcomings of one side without galvanizing, there is another kind of galvanized sheet coated with a thin layer of zinc on the other side, that is, double-sided differential galvanized sheet;
⑤ Alloy, composite galvanized steel. It is an alloy made of zinc and other metals such as aluminum, lead, zinc, or even a composite plated steel plate. This kind of steel plate not only has excellent antirust performance, but also has good coating performance;
In addition to the above five types, there are also colored galvanized steel panels, printed galvanized steel panels, PVC laminated galvanized steel panels, etc. But the most commonly used is still hot-dip galvanized sheet.
