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.

Advantages of coated aluminium coil:

  1. Light texture, easier to form

 

  1. 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.

 

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

 

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