Color-coated steel PU insulated sandwich panel is made up of two steel panels, between which the polyurethane foam is laid.

Advantages
1. The color-coated steel PU insulated sandwich panel is light in weight, easy in installation. With the steel plates as its outer layers, it not only comes with high strength, but also has beautiful appearance.
2. It has a lot of functions, for instance, thermal insulation, sound insulation, vibration absorption, etc. Additionally, the filling system applies the closed cells structure which can put an end to water vapor condensation.
3. Our product has low heat conductivity coefficient that is no more than 0.024. Because of its excellent thermal insulation property, it is really the ideal energy-saving building materials.
4. Currently, we can make Grade B1, B2, and B3 series fire proof PU panels.
5. Under the condition of the same insulation requirement, it can reduce the thickness of the building envelope, thereby increasing the indoor usable area.
6. This type of sandwich panel is resistant to deformation, and not liable to crack.
7. In the case of normal use and maintenance, it has the service life of at least 30 years.
8. Our product is highly cost effective. Though the rigid polyurethane foam materials have the unit price higher than the traditional thermal insulation materials do, it can greatly reduce the power consumption.
