High Weather-durability coating coil is one kind of Polyester coating coil, it can effectively improve the UV rejection, and extend the life time for exterior using.
Product Description
Introduction of Coated aluminium coil
A coated aluminium coil is a surface coating and coloring of aluminium using coil coating technology to ensure a uniform and complete coating over the entire surface of the product. The coating can be applied on one or both sides. Various coating systems are possible, for example, HDPE coated aluminium coil.
Applications
HDPE coated aluminium coil is used for aluminium ceilings, roofing surfaces, leftovers, cans, electronics. Its performance is very stable and not easy to be corroded. With special treatment, the surface can be guaranteed for 30 years. The weight per unit volume is the lightest among metal materials.
