Product Description
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 
Huntsman, WANHUA, etc.
Polyurethane Sandwich Panel also called PU Sandwich Panel,the top & bottom sheet of this panel is Galvanized & Pre-painted steel sheets,and core material is 5 components Polyurethane glue, it is formed by heating, foaming & laminating. Polyurethane is the best material for heat and sound insulation. It can reduce the heat transmission caused by difference in the internal and external temperature, and get to maximum efficiency of freezing and refrigeration systems. It is a new type of heat insulation material for lower construction cost.Panels are in multiple varieties and specifications to meet the need of various sites and projects.
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.
Our company right now have some different kinds of PU sandwich panels to meet different customers' and markets' requirements.
As per different joint ways,we could divide them into the following photos
Roof Panels
1) 3 ribs concealed joint roof panels 2) 4 ribs overlapping joint roof panels
Wall Panels
We have three joint ways for pu sandwich wall panels;
The left photo, two joint ways are concealed joint Wall panels with or Without 20mm decorative seam,
they are more popular for steel building exterior wall.
The Right one is tongue &groove joint way, it is popular used for cold room.

Product advantages:
The sandwich panels can be used in large industrial plants,warehouses,supermarkets, hospitals, stadiums, cold storage, activities room, buildings plus layer, clean workshop and heat insulation fire place. Commercial housings in the cities, such as exhibition halls, shopping centers, offices and other housings for exhibition and sports.The temporary facilities in the construction site, such as office, warehouse.
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.
