Product	Galvanized Steel Coil

Galvanized coils are made by dipping thin steel sheets into a molten zinc bath to adhere a layer of zinc thin steel sheets on their surface. They are mainly produced by continuous galvanizing process, that is, the rolled steel sheets are continuously dipped into a molten zinc bath to make galvanized steel sheets; alloyed galvanized steel sheets. This type of steel sheet is also made by hot dip method, but after leaving the bath, it is immediately heated to about 500℃ to form an alloy film of zinc and iron. This type of galvanized coil has good coating adhesion and weldability.There are many kinds of galvanized star flowers, including large star flowers, medium star flowers, small star flowers, and no star flowers.

Galvanized steel coils are most widely used in the construction industry. They can be used as covering materials for roofs, walls, ceilings and other buildings. Due to their excellent corrosion resistance and weather resistance, they can be used for a long time in environments exposed to wind, sun, rain and snow. At the same time, galvanized steel coils can also be used to manufacture building structural materials such as box beams, bridges, stairs, handrails, etc. They are widely used not only in the construction industry, but also in transportation, manufacturing and other industries.

Galvanized steel coils Production process

Galvanized steel coils is mainly used in construction, home appliances, automobiles, machinery, electronics, light industry,signage industry, etc. Galvanized sheet is mainly used: a large number of galvanized sheet plate used in automobile manufacturing,cooler,
construction, ventilation and heating facilities and furniture manufacturing and other fields. Galvanized become important steel anti-corrosion method, not only because the zinc can be formed in the steel surface protective layer of dense, but also because of
the zinc has the effect of cathodic protection, when the galvanized layer damage, it can still through the cathodic corrosion protection to prevent the iron base.Hot-dip galvanizing is the reaction of molten metal with an iron substrate to produce an alloy layer, thereby combining the substrate and the plating layer. Hot-dip galvanizing is to pickle iron and steel parts first. In order to remove iron oxide on the surface of iron and steel parts, after pickling, it is cleaned in an ammonium chloride or zinc chloride aqueous solution or a
mixed solution of ammonium chloride and zinc chloride.And then sent to the hot-dip plating bath. Hot-dip galvanizing has the advantages of uniform coating, strong adhesion and long service life.
