The beauty of the exterior wall of a building is inseparable from the decoration and the precise construction of the construction personnel. This is a technical problem for the problems that plague the installation of aluminum veneers. Many Shenzhen aluminum veneer manufacturers are not familiar with the installation of aluminum veneers, so such problems will always occur after installation.

Now let Shenzhen Zhongda Aluminum Products Decoration Co., Ltd. explain to you the main technical points of how to deal with the installation of aluminum veneer in Shenzhen: the aluminum veneer for installing the triangle keel suspension is installed in the vertical direction together with the triangle keel and the light steel keel. According to the board spacing, the connection is good, and then the two sides of the horizontally adjusted square board are pressed into the triangle keel. After the first side of the aluminum veneer is cross-cut, the two ends of the first side are straightened and then gradually pulled into a row of gusset boards. Adjust after buckle to ensure that the board surface is flat and the aluminum veneer is sewn vertically. The boom and light steel keel are hoisted at appropriate intervals. The distance between aluminum veneer booms is less than or equal to 1.2 meters. The distance between light steel keels is 1.2 meters. After the installation is complete, the protective film can be removed. However, in a few cases, the protective film will be retained. However, tearing off the protective film can promote the cleanliness and beauty of the exterior wall for the first time.
