If your Jinan color steel plate has been used for about ten years, you will find that some places have rusted and leaked. The acid-base corrosion of industrial emissions will cause slight corrosion and leakage, and in serious cases, the whole steel tile will fall off, affecting the normal work. The service life of colored steel tile is shortened. If the color steel plate is replaced after corrosion, it will not only affect your normal production, but also the price is very expensive.
Systematic waterproof treatment shall be carried out for the leakage prone parts of the color steel tile roof, mainly including the screw hole of the color steel tile, the lap joint of the color steel tile, the roof joint of the color steel tile and the gutter cornice.
Jinan color steel roof has been damaged by environment and climate for a long time. The temperature difference makes the color steel tile shrink and deform. In addition, heavy rainfall makes the color steel plate roof shake for a long time. Nail holes and joints will be worn for a long time, resulting in damage to the rubber pad and serious water leakage.
Some roofs have a large span and more people will step on them, which will cause ponding in the middle and increase the gravity in the middle. The more rain, the more serious the deformation of the roof. Some roofs are made of mineral wool, which can absorb water.
On rainy days, all rainwater leaked from the roof will gather in mineral wool, which will increase the weight of the roof and even cause the roof to collapse. There are high and low, and the roof leaks. Firstly, cement shall be used for waterproof construction, and sealant or waterproof coating shall be used for waterproof protection. If the adhesive is not combined with the metal, it is easy to produce cracks. If the elongation of sealant or coating is low, it will also produce large cracks.
The "waterproof gutter" is easy to handle. It is difficult for part-time personnel to find essential loopholes. Because the design size and width of the gutter are different, the construction difficulty is also different. Some are too narrow, so the excess cornice of the color plate needs to be cut off to wrap the whole gutter.
Drainage ditch leakage generally has two aspects. First, the gutter design is unreasonable, there is too much sludge accumulation, the drainage is not timely, and the residual ponding is soaked for a long time, resulting in water leakage in the gutter. If the gutter is cleaned and washed regularly, there will be no excessive ash layer in the gutter, and the rainwater can be discharged in time without being worn.
The above is the reason for the damage of Jinan color steel plate. I believe everyone knows it. If you want to know about relevant products, you can contact us. We look forward to cooperating with you.
