ASTM Standard Galvanized Steel Coil for Striping/galvanized Steel Sheet for Corrugated Roofing Sheet:
Galvanized Steel Coils: Galvanized steel coils and strips are steel products coated with a layer of zinc to enhance their performance and extend their lifespan. The galvanization process involves immersing the steel in a bath of molten zinc, creating a metallurgical bond between the steel and zinc. This results in a protective layer that shields the underlying steel from corrosion, rust, and environmental elements.
Galvanized steel strip:is a hot strip steel substrate, through pickling, cold rolling, heating reduction, zinc production process out. It is widely used because of its good anti-corrosion performance. It’s mainly used for making metal products that are cold processed without galvanizing, such as sink, reinforced door plate, light steel keel, roof, ceiling, in the construction industry can be widely applied for cold-formed steel keel, galvanized pipe, chimney, shutter doors, highway guardrail etc., can also be used in automobile, locomotive manufacturing, board manufacturing and other industries.ect.
Galvanized steel flat sheet:is cut from galvanized steel coils.It’s mainly used for roofing sheet,building wall pannel,fence,,home application,advatising,furniture industry
Galvanized Steel Coil Striping/Steel Sheet Production Process:
1.Surface Preparation: The steel surface is cleaned and treated to remove impurities, ensuring proper adhesion of the zinc layer.
2.Galvanization: The steel is dipped into a bath of molten zinc, where a chemical reaction forms a zinc-iron alloy layer on the surface.
3.Cooling and Quenching: The coated steel is cooled and quenched to solidify the zinc layer.
4.Finishing: The galvanized steel undergoes various finishing processes, including skin passing and/or tension leveling, to achieve desired thickness and flatness.
