LANREN PVDF Aluminium composite panel is consisted of 3 layers, the surface and back covers of high strength aluminum alloy sheets and the core of nontoxic low density polyethylene (PE) sheet. The painting in the surface and back aluminum sheets are from PPG.VALSPAR of USA and Becker of Sweden.
Strictly according to the international quality system ISO9001 and ISO14001 produce superior quality PVDF aluminum composite panels. Our PVDF aluminum composite panels passed GB/T1778-1999 ,SGS tests and gained CE certificate.Because of its excellent weather proof and other features, the panel becomes a very popular Cladding materials in the world.
