The corrugated colour coated sheets coating is a product obtained by subjecting a cold rolled steel sheet or a galvanized steel sheet to a surface chemical treatment (roll coating) or a composite organic coating (such as a PVC coating) and then baking and curing.
Its base steel is cold rolled sheets, hot galvanized steel sheets, and aluzinc steel sheets. The coating types can be classified into polyester, silicon modified polyester, polyvinylidene fluoride, and plastisol. The surface state of the color coated sheets can be divided into a corrugated coated sheet, a corrugated embossed sheet, and a corrugated pattern sheet.
The color coated sheets for construction are generally made of hot-dip galvanized steel sheets and hot-dip aluzinc steel sheets. They are mainly processed into corrugated sheets or sandwich sheets with polyurethane and are used for the construction of industrial and commercial buildings such as steel structure workshops, warehouses, and freezers. Roof, wall, door.
1) The corrosion resistance of galvalume steel roofing sheets is 3 to 5 times that of corrugated galvanized steel sheets, and the more severe the corrosion, the greater the difference. Therefore, in the construction roof, corrugated galvalume steel sheets AZ150 should be preferred.
If corrugated galvanized steel sheets are used, it should not be lower than Z275, and its service life is much lower than that of AZ150. Therefore, Australia and other countries have clearly stipulated that if corrugated galvanized steel sheets are used as roofing (wall), Z450 must be used.
2) AZ150 is about 10-20% more expensive than Z275, but its corrosion resistance is 3~5 times.so corrugated galvalume steel sheets has excellent performance and cost performance.
The corrugated galvanized steel roofing has a double-sided coating weight of 20-700 g/m2 according to ASTM test. The most commonly used corrugated galvanized steel sheets for building applications are Z275 and Z450, and the galvanizing amount is 275 g/m2 (the minimum thickness of the single-sided coated of the steel sheet is 19 μm) and 450g/m2.
Established in 1998, Runfei Steel Group has developed into a large-scaled enterprise, located in the city of Tianjin, which is the largest artificial harbor in north China.
