Coated Aluminium Coil

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

● Building facades

 

● Curtain wall and shading elements

 

● Roofing

 

● Roller blinds

 

● Composite walls and partitions

 

● Ceiling panels

 

● Laminate or sandwich panels

 

● Decorative panels

 

● Billboards

 

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.

Advantages of coated aluminium coil:

1. Light texture, easier to form

 

2. Corrosion resistance Because of its surface has a dense oxide film, so it has strong adhesion, anti-oxidation, acid resistance, alkali resistance, corrosion resistance, corrosion resistance, UV resistance.

 

3. Good temperature resistance, the melting point of aluminum is 660 degrees, the general temperature does not reach his melting point

 

4. The board has extremely high strength and can be cut, slit, balanced, drilled, joined, fixed and compressed at the edges.
