High Quality Z275 Hot Dipped Galvanized Steel Coil/sheet

Is a modern integrated production enterprise which incorporates the processing & manufacturing of Cold-rolled Steel, Galvanized Steel, Galvalume Steel, and Prepainted Steel, sales and logistics.The total investment of the project is 2.6 billion RMB, covering an area of Hot Rolled Coil (HRC) - PT Gunung Raja Paksi TbkOur Hot Rolled and Cold Rolled steel plate can be formed into coils. Cold rolled coils have better surface quality, thinner and with more precise size, also have good mechanical property and excellent durability and finishes, while hot rolled coils have excellent formability and weldability. Standard & Specification:ASTM A-36, ASTM A-572, JIS G 3101, JIS G 3131 Available Size :Thickness 2mm - 12mm, Width 900mm - 1524mm, Maximum 25 MT/Coil POSCO Maharashtra SteelThe hot-rolled coil passes through the pickling line, where hydrochloric acid solution is used to remove surface scale for its smooth surface finish before further processing. Cold Rolling Pickled coils are rolled in to the as normal as temperature (under of the re-crystallizing temperature) in the tandem cold rolled mills where they are

Surface treatment and coating of rolled steel coil (plate

Jun 01, 2021 · The cold-rolled steel plate should have been treated with anti-corrosion on the surface during the manufacturing process. However, on-site welding, mechanical cutting, and collision during construction are unavoidable in the construction site, which may easily cause corrosion on the section of the steel plate and damage to the galvanized layer Wholesale Galvanized Steel Sheet Z275 Gi Sheet Zinc Coated A:Our company is a professional manufacturer.
