The comparison between FRP sandwich panel and metal sandwich panel.

The FRP sandwich panel is fabricated by FRP Sheet and Pu rigid foam,its internal and external coverings are integral FRP sheet. While the metal sandwich panel is fabricated by metal skin and XPS or injected PU, its internal and external coverings are individual metal skin.The structure of former one is all closed vacuumized homogeneous construction and without any metallic support frame inside.But the metal one is opened structure and non vacuuming processing, metallic support is put into the frame. The weight of the FRP one is 30% to 70% lighter than metal one.The FRP sandwich panel have excellent insulation.It is more reliable, effective and cost-saving.
