A sandwich panel is one structure made of three layers of material: low density core inserted material in between two relatively thin steel skin layers. This sandwich setup allows to achieve excellent mechanical performance at minimal weight. The very high rigidity of a sandwich panel is achieved thanks to interaction of its components under flexural load applied to the panel: core takes the shear loads and creates a distance between the skins which take the in-plane stresses, one skin in tension, the other in compression. General information on sandwich panel structure, different sandwich core types available and the potential with respect to weight savings is available in the following reference.
1)Suface sheet:
Usually the surface sheet of PUR or PIR sandwich panels is PPGI or PPGL steel color coated sheets.PPGI is prepainted galvanized coated steel and PPGL is prepainted Al-Zn coated steel.For coating type,you could choose PE, PVDF, HDP, SMP,ect.Our strategic cooperation brands are Bluescope, Bao-steel, Shougang steel, Guanzhou steel, Yieh Phui steel,Xinyu steel,etc.
2)Polyurethane core material:
Our polyurethane core material strategic cooperation brands are D·BASF, Huntsman, WANHUA, etc.

Features Of PU/Polyurethane Sandwich Panel:
According to different usage of insulated panels, PU Sandwich Panel can be divided into three types: Wall panel, Roof panel, Cold Store Sandwich Panel. Widely used in industrial and commercial buildings, Cold Storages, Clean Rooms,warehouses and prefab buildings.
Low thermal conductivity of pu sandwich panels with excellent thermal insulation properties, can greatly reduce the thickness of periphery of the building structure, which effectively increasing the interior area of the building and save energy and costs.
