Galvanized steel plates can be divided into the following categories according to production and processing methods:
Hot dip galvanized steel plate: A thin steel plate that is immersed in a molten zinc bath to adhere a layer of zinc to its surface.
Alloyed galvanized steel plate: This type of steel plate is also manufactured using the hot dip method, but immediately after being removed from the groove, it is heated to around 500 ºC to form an alloy coating of zinc and iron.
Electrogalvanized steel plate. Manufacturing this galvanized steel plate using electroplating method has good processability.
Single sided and double sided differential galvanized steel plates: Single sided galvanized steel plate refers to a product that is only galvanized on one side.
Alloy and composite galvanized steel plate: It is a steel plate made of zinc and other metals such as lead, zinc, and even composite plating.

Our Advantages
Galvanized steel plate Z-normal zinc flake: Zinc flake obtained by crystallization at normal cooling rate, can be used for general purposes: X-small zinc flake: The cooling rate is specially controlled, and the size of zinc flake is smaller than that of normal zinc flake, suitable for painting and other occasions where normal zinc flake cannot meet the requirements; GZ Finish Zinc Flower: Small zinc flowers have undergone finishing treatment and are suitable for deep drawing and ultra deep drawing processing, as well as occasions with low surface roughness requirements.

Galvanized corrugated board is a corrugated board made by rolling the surface of steel. For its standard form, there is a clear definition in the standard, that is, galvanized corrugated board is a structural board that is bent out of a series of ready-made hexagons after surface treatment by the galvanized person, has a certain bearing capacity, and can be used in buildings. Due to the lack of joints in galvanized corrugated boards, they overcome the shortcomings of traditional building structures and are easy to disassemble, move, and install.
