1. The color of the roof tiles is accurate, the lap is tight, and the pavement error is small. Good colored cement tiles, after paving, are all straight and horizontal, as if printed, neat and beautiful. Large dimensional errors or warpage often cannot be paved. If the tile mold is made of iron sheet, it can’t produce tiles with accurate dimensions at all. No one can use this tile. For example, the width of the tile is only 2mm. If 100 tiles are lined up, the difference will be 20 cm, which is wider than a half tile. The tile will naturally become inclined and cannot be paved. If the tile is warped, the gap after paving is large, and it will not be beautiful.

2. The color is durable, the wind and the sun, the rain will not fade. Some small factories are unable to spray cement paste uniformly because of poor equipment and inadequate technology. This kind of tile peels off the patent skin in a short time, the bottom will be exposed, the color tile will be discolored, and the mottle is very ugly.

3. 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 burst at night and it will slowly peel off, which will damage the tiles. The tiles of the small factory are not compacted due to high-pressure rolling, so the service life of the tiles will not be long.

4. The color tone is soft and even, not bad, dazzling and bright, preferably matte type. Because of poor materials, small factory tiles do not pay attention to color, and often the color is black and ugly.

5. The color is durable, the wind and the sun, the rain will not fade. Some small factories are unable to spray cement paste uniformly because of poor equipment and inadequate technology. This kind of tile peels off the patent skin in a short time, the bottom will be exposed, the color tile will be discolored, and the mottle is very ugly.

6. There is no color difference between tiles. After going to the house, the color of each tile is even and uniform, there is no difference in shade, and there is no mottling.

7. The tile-shaped slope is soft and gives people a sense of beauty. The tile shape of the big factory is carefully designed by experts from the perspective of art, and it will give a beautiful and intimate feeling to the roof. The small factory tiles did not undergo this kind of scrutiny design. After the tiles were put on the house, they gave a mechanical rigid feeling and looked very uncomfortable.
