The curtain wall aluminum veneer is made of aluminum alloy materials through numerical control technology and bending technology. After the surface is chromated, it is added with fluorocarbon spraying technology. Two types of varnishes of vinylidene fluoride resin. In terms of the spraying process, the exterior decoration process includes multiple steps of two-coating, three-coating or four-coating. Through a series of processing, the aluminum veneer material has good corrosion resistance and weather resistance, and can resist the attack of ordinary acid and alkaline substances.

    Aluminum veneer materials have many different specifications and thicknesses in general production. Specifically, it can be divided from the outer decoration or the interior decoration of the aluminum veneer material, and can also be divided according to the functional difference of the aluminum veneer material.

    For aluminum veneer materials such as aluminum-plastic composite panels used for exterior wall decoration, the specifications can be divided into five specifications, ranging from 0.3 mm to 0.5 mm, in increments of 0.05 mm thickness. Aluminum veneer materials for exterior walls are generally sprayed with fluorocarbon, and polyester resin is also used for finishing.

    For the classification of aluminum veneer materials for interior walls, the specifications include public five specifications such as 0.3 mm and 0.21 mm. The coatings are mostly polyester resins and few are fluorocarbon coatings.   

    There is also aluminum veneer material with fire resistance. The thickness is increased by 0.05 mm in length, including six specifications ranging from 0.25 mm to 0.5 mm self-test. The coating is both fluorocarbon coating and polyester resin.
