How to choose the waterproof material of light steel house?

Light steel houses are now widely used in the temporary construction industry, and even replace some traditional houses. Light steel houses have many advantages such as stable structure and fast construction, but after a long period of use, there may be water leakage. This situation is mostly caused by the quality of the selected waterproof materials. The waterproof material of the steel structure roof is the key to preventing the roof from leaking. It must be thoroughly and strictly inspected when purchasing, and the specifications, performance, brand, etc. meet the requirements of relevant regulations. Inferior waterproof materials are strictly prohibited from entering the construction site.

The roof anti-corrosion project of Wellcamp light steel house manufacturer excludes the double-layered plate that is widely used in our country. This kind of steel plate is due to the physical properties of the material that lead to thermal expansion and cooling, the roof structure is exposed to the outside, the wind and the sun for a long time, the change of the steel structure causes gaps, when it rains, the rainwater penetrates into the room through the gaps, making the roof rainwater leakage. During the construction process, if the steel plate is accidentally damaged, such as damage to the waterproof layer, it will cause corrosion to the steel plate and worsen the flow of roof water. In order to prevent this situation, our company will follow the following requirements when purchasing steel structure roof waterproofing materials:

First, it has durability and durability, can resist the erosion of acid, alkali and mold, and reduce the probability of aging or cracking due to natural factors. The waterproof material should be re-checked before specific construction.

Second, it has strong adaptability to temperature changes, has elasticity and toughness, and will not crack with temperature changes.

Third, it has good sealing and avoids the existence of small leaking holes.

Fourth, choose new materials that have been technologically improved to improve waterproof performance. In addition to the structural design factors, the purchase of roof waterproofing materials should be carried out in strict accordance with the design, and large-scale factory materials with good reputation and good quality should be selected. At the time of purchase, the manufacturer is required to provide a material certificate and a certificate of conformity, and at the same time, the material is required to be re-inspected for the specifications. It should be sent to the inspection agency for inspection as required, and it can be used after passing the inspection. The building itself is a product. Qualified products may have problems if they do not conform to conventional usage methods. Therefore, relevant supervisory departments and design units should perform their supervisory responsibilities well, and monitor the quality from the start of materials entering the construction site.

The above is an introduction to the requirements for water leakage materials for light steel houses. When choosing construction materials, you must not try to buy cheap materials cheaply, otherwise it may bring great trouble to the subsequent use.
