Corrugated Roof Sheet is a variety of wave-shaped pressed panels made of colour-coated galvanized steel sheets by rolling and cold bending. Corrugated sheet has the characteristics of light weight, high strength, rich colour, convenient and quick construction, earthquake, fire and rain resistance, long service life and maintenance-free, and is suitable for building walls and external decoration of large-span steel roofs for warehouses of industrial and civil buildings
