corrosion-resistance BRICK RED ASA roofing sheets ,PVC roofing tiles

Thermal and sound insulation:

Zhongfu synthetic resin roof tile’s coefficient of thermal conductivity is 0.293 w/m.k, about a third of clay tile, one fifth of 10 mm thick cement, one over two thousand of the color 0.5 mm steel. Phoneme determined through experiments show that, under heavy rain, hail, gale, such as the weather, Zhongfu synthetic resin roof tile still can absorb well.

Waterproof:

Zhongfu synthetic resin roof tiles select high weatherability resin, density and no water absorption, no water seepage problems of micro porous, big size area, less roof seam, contact closely. Thus it has excellent waterproof performance, can save the waterproof layer.

Fireproof:

Zhongfu synthetic resin roof tile’s main body material is PVC resin. Its chemical properties of materials determines its flame retardant properties, fire prevention performance achieve B1 level.

Light weight:

Zhongfu synthetic resin roof tile is 5.5kg per square meter, belongs to the light structure material, can effectively reduce the load of the building, enhance security, and at the same time it can save construction main body material, convenient carrying, lifting, reduce construction cost.

Corrosion-resistant:

Zhongfu synthetic resin roof tile can resist acid and alkali, salt and other chemical corrosion. No chemical reaction under the experiment for alkali, salt, and less than sixty percent of the various kinds of acid for 24 hours .
