The galvanized layer can effectively prevent oxygen from contacting the metal surface, thereby slowing down the oxidation rate of the metal and improving the corrosion resistance of the galvanized sheet, so that it can be used for a long time in harsh environments without rusting, reducing the frequency of maintenance and replacement.
Galvanized coil is a kind of steel coil that has been galvanized. Galvanizing means coating the steel with a layer of zinc to improve its corrosion resistance. This treatment not only increases the service life of the steel, but also improves its aesthetics and functionality.
Pre-coated corrugated steel is a pre-coated metal sheet that combines a corrugated structure design to increase the rigidity of the sheet and provide good drainage performance. This sheet is widely used in the construction industry, especially as a covering material for roofs and walls. Its surface coating is not only beautiful, but also can resist the erosion of ultraviolet radiation and bad weather for a long time, greatly extending the service life of the building.
The hot-dip galvanizing process forms a zinc coating on the surface of the steel strip, which can effectively isolate the steel from the external environment, prevent the steel from rusting and corrosion, and greatly extend the service life of the steel strip. It is suitable for various harsh industrial and outdoor environments.
The surface of hot-dip galvanized steel coils should be clean, free of cracks, inclusions, folds and other defects. The depth and width of surface defects must comply with relevant standards. The coating thickness is one of the important parameters of hot-dip galvanized steel coils and must comply with standard regulations. Appropriate testing methods are used to measure and verify the coating thickness.
TS280GD/350GD/550GD+Z+ZA+ZM+AZ color coated steel coils are top-notch. Available in multiple grades like TS280GD, TS350GD, and TS550GD, with zinc (Z), zinc-aluminum alloy (ZA, ZM, AZ) coatings. They feature excellent corrosion resistance and durability. Ideal for construction, such as roofing and wall cladding, as well as for manufacturing various metal products where both strength and a good appearance are needed.
