Exterior Wall Decoration Rock Fiber Panel Weather Resistant Aluminum Laminate
Exterior wall decorative panel using high-strength rock fiber panel as substrate with aluminum sheet lamination and fluorocarbon or polyester coating. The aluminum laminate offers excellent weather resistance, corrosion resistance, and self-cleaning properties, available in solid colors, metallic tones, brushed finishes, and stone grain effects.
The panel is Class A non-combustible, and the high-density rock fiber substrate provides thermal insulation, wind load resistance, and fire barrier functionality. Suitable for exterior wall decoration of high-rise buildings and extreme climate regions.
Exterior wall decoration systems for high-rise building curtain walls, airport terminals, stadiums, commercial complexes, and industrial plants; suitable for prefabricated building exterior cladding systems.
