building material PVC roof plastic for roof cover construction

1.Fire retardant
2.Weather resistance
3.be fadeless at least 10 years
4.Anti-corrosive

Excellent corrosion resistance
Yingfa pvc roofing tile in the long term against acid, alkali, salt and other corrosive chemicals. Experiments prove that: In the salt, alkali and 60% following a 24-hour soaking in acid, no chemical reaction. Very suitable for acid rain-prone areas and coastal use, the effect was particularly significant.

Excellent weathering performance
Yingfa pvc roofing tile surface materials is co-extruded in ultra-weather surface layer resin to ensure the durability of products (for 15 years in quality assurance).

Fire-retardant
Yingfa pvc roofing tile is a flame retardant material, through the national fire authority of the department according to GB8624-2006 standards for testing, fire safety performance ≥ B grade.

Good Sound insulation
The tests prove that: in suffering heavy rain, high winds the impact of outside noise, Yingfa PVC roofing tile has a good absorption of the noise effect, noise down 30dB than color steel tile.

Good Sound insulation
Yingfa PVC roofing tile's thermal conductivity coefficient is 0.325w/mk, clay tile is about 1 / 310, cement tile 1 / 5, 0.5mm thick color steel tile 1 / 2000. Therefore, without considering the case of insulation layer increases, it can still achieve the best thermal insulation properties.

Excellent resistive load
Yingfa PVC roofing tile with good bearing capacity. In the lower temperature region, even if the roof of perennial snow, 2mm Anti-corrosion Complex Corrugated Sheet does not produce the phenomenon of surface damage and fracture. Been tested, in the case of support spacing 800mm, load 100 kg, sheet will not produce cracks and damage.

Excellent water resistance
Yingfa PVC roofing tile select High weather ability dense and do not water-absorbent resin, there is no pore water seepage problem, at the same time with our own patented technology accessories, completely solved the problem of seepage in screw holes

Impact resistance & Good resistance to low temperature performance
Yingfa

PVC roofing tile with a strong ability to withstand external impact. The test 1 kg steel ball from 3-meter high free-fall does not produce cracks, low temperature impact performance is also very significan

t

Excellent insulation
Yingfa PVC roofing tile is one insulation products, will also be intact in an accident discharge, offer better protection at Ray-prone areas to replace metal tile

Environmental
Yingfa PVC roofing tile does not contain asbestos and radioactive elements, and recyclable, in full compliance with the green environmental protection requirements

Installs quickly
