The size of the roof color steel tile is tight, the lap is tight, and the pavement error is small. A good color steel tile, after paving, is straight and horizontal, just like printing, neat and beautiful. The size error is small, otherwise it cannot be paved. If the gap is large after the paving, the water leaks, and it is not beautiful. The roof tiles are made by rolling metal sheet metal. After the size is set in advance, the tiles are automatically rolled to form.

The color steel tiles produced by our company are not faded by the wind and sun for many years, and do not leak after rain. Some small manufacturers will have paint scratches during the rolling process of the color steel plate because of the poor equipment and inadequate technology. After the paint surface of the color steel plate is cut off, it will grow rust and leak rain, and the anticorrosion effect will be worse. . This kind of color steel tile is exposed in a short period of time due to the peeling of the paint skin, and the color steel roof tile is not bright, and the mottle is very ugly.

Good frost resistance. In the north, it is common for winter temperatures to fall below minus 10°C. If the density of the tile is not good and the water absorption rate is high, if the snow water is absorbed during the day, the colored layer will swell at night and the color layer will burst, which will slowly peel off and damage the tiles. The compactness of the colored steel tiles rolled by the machines of small manufacturers is not good, so the service life of the tiles will not be long.
