Product Description

product introduction:

Galvanized steel coil is created through a hot-dipped process that dips the metal into zinc for a nice smooth coating.The coating creates a strong rust resistance and prolongs the life of the steel coils.

Highlight advantages:

The main advantage of galvanized steel coil is its corrosion resistance. The zinc coating serves as a barrier between the steel and the environment and will sacrifice itself in order to protect the underlying steel; Meaning the zinc will degrade much sooner than the steel itself. Additionally, it offers good processability and formability.

Galvanized steel coil has a wide range of applications, and its advantage is that it has a long anti-corrosion period. It is mainly used for home appliances, office panels, roof sheets, automotive panels, construction and substrate of prepainted steel coils.

Hot dipped galvanized steel sheet & coil is made of carbon steel coated in zinc utilizing the hot-dip process. The end result of this process is a layer of zinc on each side of the steel sheet or coil that is tightly adhered to the steel through the formation of an iron-zinc alloy bonding layer. This bonding layer is formed by a diffusion process while the heated steel is in contact with molten zinc.

Steel coil production process:

The production and processing of galvanized steel coils can be divided into three steps: first, the entire coil is pickled to remove rust and dirt, so that the surface of the galvanized steel strip can achieve a bright and clean effect; after pickling, pass ammonium chloride or zinc chloride It is cleaned in an aqueous solution or a mixed aqueous solution of ammonium chloride and zinc chloride, and then sent to the hot-dip plating tank for the galvanizing process; after the galvanizing process is completed, it can be put into storage and packaged.
