Scratch Resistance 25 / 5UM PVDF Coating Stone Pattern Aluminum Coil

Scratch Resistance 25 / 5UM PVDF Coating Stone Pattern Aluminum Coil

Stone Pattern Aluminum Coil is a premium decorative material that replicates the natural texture

and appearance of stone through advanced surface treatment technology. Combining the luxurious

aesthetics of stone with the practical benefits of metal, it offers an innovative solution for modern

architectural decoration.

Common-used Aluminum Alloy
