Corrugated sheet is also called contour sheet in various weave shapes made of color-coated steel sheet, galvanized sheet and other metal sheets through rolling cold bending. It is applied to the roof, wall as well as decoration of interior and exterior walls of industrial and civil buildings, warehouses, special buildings and large-span steel structure houses. It features light weight, high strength, rich color and luster, convenient and fast construction, earthquake resistance, fireproofing, rain protection, long service life, no maintenance, etc.

Galvanized and aluminized corrugated steel sheets are durable roofing and siding materials used widely in industrial and agricultural buildings. Made of high-quality steel coated with zinc or aluminum, these corrugated sheets offer superior corrosion resistance and weatherability. Galvanized steel sheets have a zinc coating that protects the base metal from rusting. The galvanizing process involves applying a thin layer of zinc to the surface of the steel.

Zinc corrodes slowly and forms a protective coating in the presence of moisture, shielding the steel from corrosion. Galvanized steel can last up to 100 years in many environments. It is a cost-effective and low-maintenance solution for roofing and siding.Aluminized steel sheets are coated with an aluminum-silicon alloy using a hot-dip process. The aluminum coating provides excellent heat reflectivity and corrosion resistance, especially in high-heat applications. Aluminized steel can last 30-50 years with minimal maintenance required. It offers superior high-temperature performance compared to galvanized steel.These corrugated metal sheets are durable, moisture-resistant, and weather-resistant. They are suitable for roofing and siding in agricultural, industrial, and commercial buildings with high humidity and chemically active environments such as waste and water treatment plants.

Regular steel structures would rapidly deteriorate in these conditions. The unique corrugated profile of the sheets enhances structural stability and sheds rainwater and snow efficiently. The parallel corrugations effectively stiffen and strengthen the sheets in a lightweight profile. They provide an attractive weathered look over time. Corrugated steel and aluminized steel are environmentally friendly, recyclable, and sustainable construction materials. They deliver decades of service at low lifetime costs.In summary, galvanized and aluminized corrugated steel sheets are durable, low-maintenance roofing and siding materials ideal for harsh environments. With excellent weatherability, high corrosion and heat resistance and a distinctive profile, these sheets provide a sustainable and cost-effective building solution.
