970 sandwich roof is made from two layers of pre painted steel with the hard foams of polyurethane inside.
Aluminum composite and sandwich panel is light self-weight, Heavy Load-bearing Capacity:
Good Temp-keeping & Heat insulation, fine fireproof.
Polyurethane sandwich panel is composed of two layers of pre, painted steel sheets with the hard form of polyurethane between: which features fireproof materials. It is suitable for the various roofs and walls referring to the large-size factory buildings, storages, exhibition halls, gymnasiums,
Freezing stores, purification workshops which features temperature-keeping, heat insulation weight-bearing,weatherproof with the rich color and good appearance.Light Self-weight: Installation is convenient and flexible without the large-size lifting devices so that the construction period is limited with the lower comprehensive costs.
Heavy Load-bearing Capacity: It features high strength and high rigidness and is suitable either for the weight-bearing structure or for the protective structure.
Good Temp-keeping & Heat Insulation: Average thermal conductivity 0.023w/m.k
Fine fireproof: Test by national quality inspection center for fireproof building material, all its index reach grade B1 and grade A of GB8624 respectively.
Flexible Application: As the continuous production line is controlled by the computer system, the length of the said compound sheets will be decided and selected according to the designing requirement, transport and installation conditions. It is possible to select the different thickness of the composite panels in accordance with the roof load-bearing and purline distance.
