GI Coil:
Hot dipped galvanizing is one of the most effective means of delaying environmental corrosion of steel materials. It immerses the cleaned and activated steel products in molten zinc liquid. Through the reaction and diffusion between iron and zinc, the steel products are The surface is coated with zinc alloy coating with good adhesion.
Compared with other metal protection methods, the hot dip galvanizing process combines the physical barrier and electrochemical protection of the coating, the bonding strength between the coating and the substrate, the density, durability, maintenance-freeness and economy of the coating. It has unparalleled advantages in terms of durability and adaptability to the shape and size of products.
At present, hot dipped galvanized products mainly include steel plates, steel strips, steel wires, steel pipes, etc., among which hot-dip galvanized steel plates account for the largest proportion. For a long time, the hot-dip galvanizing process has been favored by people because of its low plating cost, excellent protective properties and beautiful appearance. It is widely used in automobiles, construction, home appliances, chemicals, machinery, petroleum, metallurgy, and light industry. , transportation, electric power, aviation and ocean engineering and other fields.

How does the hot-dipped galvanizing (HDG) process work?
This technique, also called HDG, is now a lot more common. Galvanizing is basically the process of adding a coating on any base metal for the purpose of increasing corrosion resistance and durability. Hot-dip galvanizing is a form of galvanization. It is the process of coating iron and steel with zinc. That is, the surface of the base metal is coated with a zinc layer by immersing the metal in a bath of molten zinc at a temperature of around 450 °C (842 °F).
Galvanized steel is widely used in applications where corrosion resistance is needed. But its cost is much lower than the cost of stainless steel.
