Name:   QWS Series Cement Tiles »

Company:  Changshu Tongjiang Manufacturing Co., Ltd. 

Description:  Features:
1) Waterproof:
The tiles make the rainwater drains more quickly and smoothly, eliminate the
rainwater counter-flowing (which usually occurred on roll formed tiles) even on
horizontal roof. The unique waterproof ability enables the use of color tiles in
rainy area or on surface with 15 gradient
2) Superior intensity:
The colored tiles have beautiful appearance, smooth surface, precise
size and even density. The special protection coating on external surface enhances
the decorative effect and protection of colors. The antiflex cracking intensity above
200kg is sufficient for constructors to walk freely on laid roof
3) Construction convenience:
The tiles can be either vertically laid or transversely constructed conveniently. On
common grade roof, the tiles can be settled without tile batten, which can only
be done by compression molded colored tiles. The tiles can also be cut with wet
method at any angle with cutting machine for different construction needs
4) Super high wind resistance:
The tiles can be used for inclined roof between 15 and 85 gradients, 9 pieces for
each square meter. The falling gradient is irrelevant to the inclined plane. The tiles
have larger effective area and the construction is simple and flexible
5) Excellent heat insulation:
Test report issued by Japan Solar Energy Research Center shows that, during
summer, the daily average temperature on the internal surface of roofing laid with
compression molded colored tiles and tile battens is 71.4°F (21.89°C),
greatly reduces the load of air-conditioner. The heat insulation is better than that of
other tiles
6) Freeze-thaw test:
The 25 circulation freeze-thaw test shows that the freeze-thaw resistance of
colored tile conforms to JIS standard, far better than other tiles
7) Permeability resistance:
Since the colored tiles by compression molding with large-tonnage press have high
density and low water absorption, its permeability resistance is far better than
other tiles. The water penetration won`t occur even in rainy and snowy areas
