3D Effect Grain Aluminum:
3D effect pre-painted metal material has the appearance of wood,hand feeling of the concave-convex formed by time and various textures.It has the advantages of thermal insulation,heat preservation,good leakproofness.Meanwhile,it has the characteristics of stable performance&anti-corrosion.
Advantages & Characteristics:
*Much higher adhesion between coating & substrates.
*PE & PVDF paint,high durability & wide application.
*Compared with stone material,could be punched or bent to an shape.
*Distinct & vivid texture.
