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.
PU Sandwich panel (Polyurethane sasndwich panel) is composed of 2 layers of weather-proof colored steel sheets and jetted the hard forms of polyurethane between 2 layers. It is suitable for the various roofs and walls referring to the large-size factory buildings, storages, exhibition halls, gymnasiums, freezing stores, purfications workshops, etc, which features heat insulation, weight bearing, weatherproof with the rich colorfulness and good appearance.
Polyurethane foam is been sandwiched between the two outer skins and hence is known as PU sandwich panels. We are engaged in manufacturing reliable PU sandwich panels in variegated specifications.Those two layers are available in profile with zinc coated, galvanized steel, embossed aluminum, stainless steel or other material sheets.

Features
1. Good fireproof and flame-retardant performance. After adding flame retardant, PU board is a kind of refractory self-extinguishing material. It can effectively prevent fire spread while meeting fire, especially after a system of fire prevention treatment ,it can be sealed to form a non-flammable product.
2. Excellent Waterproof performance. PU sandwich board has the advantage of low water absorption rate,good water vapor permeability resistance, independent state of foam pores.mutual non-communication,closed cell rate of more than 90%, dense structure of micro porous foam material, more compact surface in contact with air,less water permeability and belonging to hydrophobic material.
3. Good weather resistance. Ability to withstand the most severe local climate and its changes, whether high temperature or cold climate, polyurethane PU board will not cause damage or deformation of exterior wall insulation system. Polyurethane PU plate reduces the strength and difficulty of the project, saves the project cost and construction time.
Application
1. Clean workshops of industries like pharmaceuticals, cosmetics, electronics, food & beverage.
2. Portable houses, combined rooms, building top shelters, warehouses.
3. Outer or partition wall of light steel construction buildings.
