Features (Polyurethane Sandwich Panel): 1) Structure: a) Upper and lower layer: uses Painted galvanized steel sheets b) Middle: condensed polyurethane foam board 2) Width: 1,200mm, 1,18mm 3) Thickness: 40mm, 50mm, 60mm, 75mm, 80mm, 100mm, 125mm, 150mm 200mm, 225mm, 250mm 4) Length: depending on the design and conditions of transportation 5) Thermal conductivity: 0.032kcal/m.h.c 6) High load-bearing ability and good integral stiffness: polyurethane core material are injected into two layer steel sheets as liquids then solidified under the pressure,and polyurethane itself is colloid,thus it makes PU panel have very good integrality.Also,because upper surface of the PUR panel has been formed as special designed profile.Its integral stiffness is much higher than other similar kinds of materials. 7) PU panels are of Light Weight 8) Simplified connections for both Roof & Wall panels that make installation much easy. 9) Payment terms T/T .
