The reason for the damage of the cornice of the color steel plate

If the color steel plate has been used for a long time, some places have rusted and leaked. The acid-base corrosion of industrial emissions will cause slight corrosion and leakage, and in severe cases, the entire color steel tile will fall off, affecting normal work. The service life of color steel tiles is shortened. If you change the color steel plate after wearing rust, it will not only affect your normal production, but also be very expensive.

The leaking parts of the color steel tile roof should be systematically waterproofed, mainly including the screw holes of the color steel tile, the overlap of the color steel tile, the roof joint of the color steel tile and the cornice of the gutter.

Color steel roofs have long been damaged by the environment and climate. The temperature difference of the climate causes the color steel tile to shrink and deform. In addition, strong winds and heavy rain caused long-term vibration of the color steel roof. The nail holes and joints of the iron sheet will be worn for a long time, resulting in damage to the rubber pad and serious water leakage.

Some roofs have large spans, water will accumulate in the middle, and gravity will increase in the middle. The heavier the rain, the more severe the roof deformation. Some roofs are made of mineral wool, which absorbs water.

On rainy days, all the rainwater that leaks from the roof will collect in the mineral wool, adding weight and even causing the roof to collapse. Water seepage at the corner of the parapet across the roof. During the initial waterproof construction, the splayed corners should be smoothed with cement, and waterproof protection should be carried out with sealant or waterproof coating. Cement does not bond with metal and is prone to cracks, and sealant or paint has a small elongation rate and can also generate larger cracks.

Dealing with "gutter waterproofing" is easy and difficult. It is difficult for part-time professionals to find essential leaks. Because the design size and width of the gutter are different, the construction difficulty is also different, and some are too narrow, so it is necessary to cut off the redundant color steel plate cornice and wrap the entire gutter.

Drain leaks generally have two aspects. First, the design of the gutter is unreasonable, the accumulation of silt is too thick, the drainage is not timely, and the residual water is soaked for a long time, causing the gutter to leak. As long as the gutter is cleaned and flushed regularly every year, there will be no excessive accumulation of ash layers in the gutter, and rainwater can be discharged in time without wear and tear.
