color coated aluminum coils top alloy 3003 prepainted aluminum coil for roofing sheet
The base material uses aluminum-magnesium-manganese alloy after coating into rolls.
According to the different shaping requirements of the roof of the construction project, it is pressed and processed into different shapes on site and then installed in combination with other functional layers such as insulation layer, can be widely used in building roofing system.
Common specifications
Thickness of substrate: 0.5~1.35mm, width not exceeding 1600mm (customized specification acceptable).
Product Features
- With a life expectancy of more than 50 years (10-15 years for color steel)
- Color permanence up to 30 years or more (color steel 5-10 years) - Self-weight as low as 2700Kg/㎥ (color steel plate 7850Kg/㎥)
- One-time installation does not require post-maintenance (color steel plates are easy to corrode and require long-term maintenance at a later stage)
- Aluminum oxide film can prevent oxidation (color steel plate is prone to oxidation and corrosion)
Advantage
- Pre-roller coated Al-Mg-Mn coil after 20 years of production technology process precipitation, from the selection of base material, to the process of treatment agent are used in stable quality of industry well-known brands
- The production process is rigorous and meticulous after 3 pre-treatment, 3 coating and 2 baking, 12 inspection, quality delivery is more guaranteed.
