Product Details

Galvanized Steel Coils is also called hot-dip galvanized steel coils as it is produced by immersing steel in a zinc bath, which requires a pretreatment process when steel passing through different baths for preparing the surface zinc coating. First, use chemicals to clean surface of the steel then another chemical treatment for the steel coils passing through a bath of melted zinc at temperatures around 460 degree. When finished the products shows smooth and shiny appearance. To store for a longer period, the hot-dip galvanized coils can be delivered with a final oil coating, according to the customers demand. If processed by further cold forming and bending processes, it will has much better ability.  
Where to use:
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. Recommend 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 – 180 grams per square metre.
