Galvanized coil: a thin steel sheet that immerses the steel sheet into the molten zinc bath to make its surface adhere with a layer of zinc. It is mainly produced by continuous galvanizing process, that is, the rolled steel plate is continuously immersed in the zinc melting bath to make galvanized steel plate; Alloyed galvanized steel sheet. This kind of steel plate is also made by hot dip method, but it is heated to about 500 ℃ immediately after coming out of the groove to form an alloy coating of zinc and iron. The galvanized coil has good coating adhesion and weldability.
– Especially produced for various usage purposes
– Long life of 4 times longer than other normal
– Effective corrosion sheets
– Good heat resistance
– The chormated, anti-finger layer is equipped:
– Stain-proof and oxidization resistance
– Keeping the surface of the products shiny for a long time
– To reduce cracking, scratching coating during stamping, rolling.

Hot dip Galvanized steel coils are widely used in the construction industry, as raw material for the production of corrugated panels, fencing products, drywall panel profiles, ventilation systems etc. Recommended for both outside and inside usage, galvanized steel has a high resistance to corrosion in different environments, due to a protective layer of zinc of 100 – 275 grams per squaremeter.
