1. Fireproof 2. Low thermal conductivity 3. Sound-absorbing 4. High compressive strength

Features: 

1.Composed of 2 layers of weather proof colored steel sheet and jetted hard forms of polyurethane between 2 layers                                                                                    

   (fireproof material).

   Suitable for varioud roofs and walls referring to the large size factory buildings,storages,exhibition halls,gymnasiums,freezing stores and purification workshops (tempkeeping,heat insulation,weight bearing,weatherproof,rich color and good appearance).

3. PU density:35 to 40kg/m3. 

4. Installation is convenient and flexible without the large-    size lifting devices so that the constrution period is limited with the lower comprenhensive costs

5. Heavy load bearing capacity:high strength and high rigidness ang is suitable either for the weight -    bearing structure or for the protectivve structure. 

Good temp-keeping and hest insulation.

Fine fireproof:test by national quality inspection center for fireproof building material,all its index reach grade A1

Packing:as per your requirement....

In the production and installation process does not produce any gases harmful to humans.
