Corrugated steel sheet introduction:
1. Corrugated steel sheet main structure:
Corrugated steel sheet is carbon steel sheet coated with aluminum-zinc alloy by a continuous hot-dip process described in Production Methods. The nominal coating composition is 55% aluminum and 45% zinc. A small but important amount of silicon is included in the coating alloy.
2. Corrugated steel sheet application scope:
Corrugated steel sheet is most commonly used for commercial, agricultural, and industrial purposes, however, it is now also being recognized as an excellent form of residential roofing. Corrugated steel sheet is also known as sinusoidal, corrugated iron or wriggly tin.
3. Corrugated steel sheet main features:
1)Combine the excellent barrier corrosion protection of aluminum with the galvanic protection of zinc
2)Preferred product for long-term resistance to atmospheric corrosion
3)Superior corrosion resistance.
