Roof aluminium sheet are Aluminum-Magnesium-Manganese alloy 3003 3004 special used for metallic roofing, the thickness is 0.5mm-1.2mm. Typically, the 3003 and 3004 aluminum roofing sheet are coated with PE and PVDF coating to have lovely look and long provider existence. After shade coated, the aluminium roofing sheet machine can withstand corrosion and sunshine, and the lively life can be so long as 25 years with out fade.
Aluminum, magnesium and manganese roof sheet, as its name implies, are fabricated from alloys of aluminium, magnesium and manganese. Aluminum is light in weight and not clean to oxidize. Magnesium is tender in nature. Manganese metallic has top corrosion resistance and durability. The aluminum roofing sheet fabricated from the 3 alloys have the traits of mild weight, corrosion resistance and strong plasticity. There are 3003 and 3004 aluminum sheet metallic usually used in Al-Mg-Mn alloy plates. The essential distinction among 3003 aluminum roofing sheet and 3004 aluminum roofing sheet is that the content material of magnesium and manganese is distinctive. The 3003 aluminum alloy is harder, while the 3004 aluminium alloy is softer, and the fee of 3004 aluminum alloy is greater steeply-priced.
Aluminum, magnesium and manganese roof aluminium sheet are without delay exposed to the air. Considering the factors along with wind resistance, strain strength and anti-corrosion, the chosen aluminum sheet alloy calls for strict processing. The outdoors ornament of the roof machine now not most effective has exact water resistant and thermal insulation overall performance, however additionally has a smooth and clean appearance.
