The use of colored sand metal tiles will not have this trouble, because it can withstand freezing and can withstand the low temperature of -45℃ roofing after testing. The color stone metal tile is made of aluminized zinc steel plate, high temperature ceramic sintered colored sand and acrylic polyester protective coating. The colored sand of the colored stone metal tile needs to be roasted and expanded at a high temperature, so that it not only has a small air barrier, but also has the functions of antibacterial, sound absorption, non-absorbing water and freezing resistance. The acrylic polyester protective coating on the surface of the colored sand prevents the snow from leaking to the colored sand particles in the lower layer after the snow melts. Therefore, the colored stone metal tile can withstand strong cold, freezing and other phenomena, and can effectively reduce the adverse consequences caused by snow accumulation.
The reason why traditional tiles easily crack in winter is that the snow melts during the day, the tiles absorb the snow water, the temperature drops at night, and the snow water freezes again. The density of ice is 0.9, and the density of water is 1.0. Under the same quality, the volume of ice is larger than that of water, so the roof is easily cracked by ice.
Everyone knows that asphalt shingles have good weather resistance. In fact, in addition to it, metal shingles are also a good helper to resist the cold weather in the north. In the northern winter, the rain and snow seasons have a great impact on people's lives. After the snow melts, there will be cracks and water leakage, and there are countless similar situations.
