Bansal Metallics India pvt ltd. Is an authorized distributor and supplier of Bhushan Power “ Aarti Suraksha” GC sheets/ Corrugated GI sheets and JSW(Jindal Group) GC sheets which comes under “JSW Vishwas GC sheets” brand. Heavier gauge GI corrugated sheets of SAIL is also available with us. We are also dealer of SAIL coated ptroducts.We are supplier of both GC wider as well as narrow. GC is an abbreviation of Galvanized corrugated. GC sheets are manufactured by rolling GP coils / sheets which are manufactured from HR/CR coils through following processes:
1. PICKLING - In this process Base steel- CR or HR steel undergoes acid bath which removes contaminants, scales ,rusts or oxides over the surface and cleanses the surface for proper adhesion of zinc.
2. Hot dip galvanizing - This is the main process wherein zinc coat is applied on pickled steel by immersing it in hot zinc bath maintained at 460 degree centigrade. This is a continuous hot galvanizing process.The chemistry of the bath is carefully controlled to ensure proper adhesion and formability of the applied zinc together with bright blemish free uniform spangles. Coating mass of zinc ,as we term in gsm(grams per square meter), is also controlled in this process.
3. Chromating - The galvanized coils are chromated to improve its resistance to white rust. The chromating parameters are continually monitored and sheets are regularly tested through salt-spray tests to ensure the performance of this process.
