Porta in FRP a tenuta stagna

This door is made of FRP. What is FRP? It is fiber reinforced plastics. This material has merits of light weight, high strength, corrosion resistance, excellent insulation, low thermal conductivity, good designability. Besides, this material is resistant to moisture, so the weathertight fuction performs well. Compared with metal door, FRP weathertight door has low thermal conductivity, so it has excellent performance in heat preservation and sound insulation. This door is suitable for the gate which requires a high strong and light weight door.
