Chongqing Kaixian Nianxing Plastic Factory, which has been established for many years, launched a new product, pvc corner protection in 2012. This product is a new type of building material specially designed for difficult construction of wall corners, door sidebars and window corners. With its unique characteristics of environmental protection, weather resistance, and aging relief, its strength and toughness have enabled people to safely replace various traditional building materials such as steel, wood, and aluminum. The current construction process of wall corners in China has followed the traditional construction method for decades, which is inefficient and complicated. And during the use of the completed building, the corner is very easy to be damaged: on the one hand, it is because the contact frequency of the corner is too high, and on the other hand, it is because the corner is not strong enough. The damaged external corner was not repaired by professional maintenance personnel, which reduced the quality of the project. In particular, the door and window corners and family houses are generally treated by edging, but this decoration method not only wastes a lot of wood, but also wastes a lot of money for decoration, causing great pollution. At present, the internationally commonly used PVC corner bead is made of high grade PVC raw materials, which is environmentally friendly and corrosion resistant. Impact resistance, aging relief and good weather resistance. It has excellent mechanical and mechanical properties. Its popularization and use can effectively solve the common quality problems such as the internal and external corners are not straight, not beautiful, and the corners are easy to be damaged in construction
