Introduction:
PU panel wall sandwich means that the inner/outer layer is made of high-grade metal materials such as color steel plate, aluminum plate, stainless steel plate etc., and the thermal insulation core material is PUR (PIR) rigid polyurethane thermal insulation foam. A high thermal insulation wall panel system with excellent bearing capacity, the preferred building material for high-grade building walls. Using the roller principle, the foam molding is developed by a continuous production line imported from Italy at one time. It is a new type of high-grade building material that integrates heat preservation, heat insulation, load bearing and fire prevention; it is rich in color and beautiful in appearance. It has the characteristics of fire and flame retardant, wide operating temperature range, low thermal conductivity, non-toxic and tasteless, waterproof and moisture-proof, and simple construction. Therefore, it is widely used in the roofs and walls of high-end buildings such as large industrial plants, power plants, hangars, exhibition halls, gymnasiums, cold rooms, purification workshops, and warehouses.

Polyurethane color steel sandwich panel product features：
1.Excellent performance in thermal insulation
2.The screw connection is convenient and efficient.
A). The snap connected by PU sandwich roof panel , which avoids rainwater seepage and saves the amount of accessories.
B). The PU panel wall adopts yin and yang port plug, beautiful appearance, saving spare parts consumption, easy construction.
3.Flexible and convenient installation
The composite panel not only greatly reduces the cost of basic engineering and structural engineering of the building, but also can be disassembled and assembled for many times in a long life, and the construction and installation are flexible and convenient, and the comprehensive benefit is very significant.
4. Good fire resistance
The core material is B2 grade flame-retardant material, its oxygen index is not less than 26, it will not melt when burning, and there is no black smoke and no pyrolysis droplets. It is the most ideal building decoration board with the most ideal fire rating at home and abroad.
