Fiberglass Reinforced Plastic (FRP) sandwich panels provide an incredible structural engineering, they are light weight, non-magnetic, non-metallic, corrosion resistant performance and excellent in thermal insulation. Fiberglass Reinforced Plastic (FRP) sandwich panels composite by laminating FRP sheet as surface at both sides, inner core materials apply with optional range Polyurethane Foam (PU), Extruded Polystyrenes Foam (XPS) and also Expanded Polystyrenes Foam (EPS).
