Features of Box Profile Steel Roof Sheets:
1). Extraordinary thermal insulation: The coeficient of heat conductivity is 0.325 w/m. K.
2). Good sound insulation
3). Excellent corrosion resistance performance
4). Good resistance to impact and low temperature: This tile doesn't crack after 1KG steel ball falls, on it from 3 meters high. Moreover, the resistance to impact under minus 40 ° C low temperature is also very outstanding.
5). Excellent waterproof performance: The high weathering resistance resin adopted in the roofing tile is compact and does not absorb water.
6). Strong fire resistance: The inner material PVC resin is difficult-flammable material, fire proofing performance Is ≥ Class B1.
7). Stable volume: The expansion coefficient is 4.93× 10-5 mm/mm/° C
