Aluminium Coils for Roofing System
Aluminum coil material contains Manganese, Magnesium, Copper, Zinc, Iron, Tin and other alloy components, with high strength and good weather resistance, stain resistance, easy welding and bending processing, and more than 50 years of architectural design service life, etc., is widely used in roofing and exterior wall materials.
Related Aluminum alloy grades are:
1. 6XXX series of aluminum alloy has higher strength, the main alloy is Magnesium, Silicon, Iron, generally as an extruded profile, used as curtain wall, daylighting roof keel and tans.
2. 3004 alloy grade: Aluminum,Magnesium,Manganese (AlMn1Mg1), due to moderate structural strength, weather resistance, stain resistance, easy welding bending processing, is generally recognized as a building design service life of more than 50 years of roof wall materials;
3. 5052 alloy: ship grade alloy material, according to the Marine climate architectural design, can choose 5052 aluminum alloy with stronger corrosion resistance.
