Polyester Coated Aluminum Veneers for Building Exterior Walls
Polyester coated aluminum veneers use aluminum alloy sheets as the base material. The sheets are processed through cutting, marking, corner shearing, bending, arc forming, argon arc welding, grinding, assembly and polishing. After chromate conversion treatment, a uniform and dense polyester coating is formed via polyester spraying. Featuring rich colors, high cost-effectiveness and easy installation, they are suitable for interior and general exterior decoration projects.
