Specification :

Extruded polystyrene sandwich panel is formed by two layer of color steel plate on the surface and with extruded polystyrene ( XPS) foam in the middle after heating and pressurizing.
Uses: As the surface of the panel adopts color steel sheet ( or color-dip galvanized steel plate) , it has a good anti-corrosion, antirust and weather resistance, it is widely used in the industrial plants, warehouses , public buildings, cold storage and other projects.
Structure
Outer surface of the plate: Color-dip galvanized steel ( aluminum galvanized steel sheet or color steel plate) .
Upper surface of the plate thickness: 0.5mm
Thickness of steel plate under the surface: 0.4mm,
Thickness of the material can be customerized.
Core material:
Our extruded polystyrene is of high compressive strength, low thermal conductivity, low water absorption, low water vapor permeability, long life and other unique characteristics of high quality thermal insulation.

Product specifications:
1) Length ( mm) : 1200, 1800, 2400,
2) width ( mm) : 600, 900, 3)
Thickness ( mm) : 6, 10, 15, 25 , 30, 40, 50, 60, 70, 80. .

Joint method: inserting type and invisible buckle

Characters:
1) Advanced technology: a fully automatic continuous production equipment, all major sectors are computer-controlled, production quality meets European standards, the value of equipment is nearly 50 times higher than other light sheet production equipment.
2) good performance of heat insulation: thermal conductivity as low as 0.027 W / mK.
3) Good Stiffness: After the polystyrene core material is shaped as a whole, and through heating and pressurizing, it is stuck to the surface of the steel plate. After figuration the sandwich panel has excellent integrity; and there is pressured waves on the upper surface on roof panel, the overall stiffness is better than other similar materials, by connected and fixed with the purlin the stiffness of the wall and roof panel is improved greatly.
4) Strong and reasonable fixing method: the roof panel is fixed by the special made tapping M6 and jointed with the purlin, the tapping is in the wave crest of the surface of the roof to improve water proof character, moreover due to the special structures of the tapping, for example, there is a plastic cap on the screw cap to avoid leakage. The buckling joint method of the roof panel also prevents leakage.
5) Short installation: no more process on the install site, it can not only keep clean of environment without influencing other production stages but also shorten the time of fixing back plate.
6) Anti scratching : There is a pressure-sensitive adhesive film on the surface of the panel to protect the coating surface from scratching damage.
