Stone grain aluminum curtain wall cladding
Aluminum stone panel is a high quality decorative material made from high quality aluminum alloy, it is processed according to the size, shape and structure of the installation requirements. The surface is coated with fluorocarbon paint and finished with Italian marble patterns, in the way of secondary melting in high temperature vacuum treatment to print the patterns on the fluorocarbon coating of aluminum panel. Marble grain Aluminum panel is produced from internationally advanced new pattern decoration material, the pattern is lifelike, luxury and elegant, the color texture is gorgeous and wearing resistant, it doesn't not contain formaldehyde and won't volatilize harmful and poisonous gas. With this advantage, the aluminum stone panel has become the first option of high class building and decoration material.
