Roof aluminum panels are aluminum-magnesium-manganese alloy 3003 3004 specially used for metal roofs, with a thickness of 0.5 mm-1.2 mm, usually 3003 and 3004 aluminium roofing sheet panels are coated with PE and PVDF coatings, with beautiful appearance and long service life. The color-coated aluminum roofing system is resistant to corrosion and sunlight, and has a service life of up to 25 years without fading.
Aluminum, magnesium, manganese roofing panels, as the name suggests, are made of alloys of aluminum, magnesium, and manganese. Aluminum is light and not easy to oxidize. Magnesium is soft in nature. Manganese metal has good corrosion resistance and toughness. Aluminum roof panels made of these three alloys are characterized by light weight, corrosion resistance and strong plasticity. Aluminum-magnesium-manganese alloy sheets are commonly used 3003 and 3004 aluminum sheets. The essential difference between 3003 aluminum roof panel and 3004 aluminum roof panel is the content of magnesium and manganese. 3003 aluminum alloy is harder, 3004 aluminum alloy is softer, and 3004 aluminum alloy is more expensive.
Aluminum, magnesium and manganese coated aluminium roofing sheets are directly exposed to the air. Taking into account factors such as wind resistance, stress strength, and corrosion resistance, the selected aluminum plate alloy requires strict processing. The exterior trim of the roof system not only has good waterproof and thermal insulation properties, but also has a smooth and smooth appearance.
