Pressed corrugated steel sheet (roofing sheet) refers to the steel sheet formed by cold pressing or cold rolling. The steel sheet is made of coloured steel sheet, galvanized steel sheet, stainless steel sheet, aluminium sheet, anticorrosive steel sheet or other thin steel sheet. The profiled steel sheet has the characteristics of light weight, high strength, low price, good seismic performance, fast construction and beautiful appearance.The corrugated metal is a good building material, mainly used for guardrail, floor and other buildings, such as airport terminal, railway station, stadium, concert hall, grand theatre, etc. According to different application requirements, the profiled steel sheet can be pressed into a wave type, a T type, a V type, a rib type and the like.
The purity of the coating is high, so the corrosion resistance of the coating at the same thickness is better than that of hot-dip galvanized products. According to the test, under the same conditions, according to the American standard (ASTMB 114), the red rust resistance time of a micron coating is 12 hours for electrogalvanizing and less than 10 hours for hot galvanizing. However, it is very difficult to obtain a thick electro-galvanized coating (large power consumption, high cost, and technical difficulty). As a color-coated substrate, the use of electro-galvanized is also mainly applied to home appliances, steel furniture, doors and windows, and the like.
Our products are widely used in many fields, such as industrial buildings (corrosive workshop roofs, walls, inner suspended ceilings), building materials (outdoor enclosure, inner decoration), light weight steel structures(roof purlin, wall purlin) etc..
