Product Description:

Galvanized steel strips 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 –180 grams per square metre.

Hotdip galvanized steel strips are produced by immersing steel in a zinc bath. An appropriate galvanizing process requires a pretreatment process during which the steel passes through different baths which prepare the surface for zinc coating. In this stage, chemicals are used to clean the surface of the steel. After the chemical treatment, the steel coils pass through a bath of melted zinc at temperatures around 460 ° C. The resulting uniform coating is finished through a process of skin-passing to provide smooth and shiny appearance of the finished product. To store for a longer period, the hot-dip galvanized coils can be delivered with a final oil coating, according to the customer’s demand.
