Since the late 1970s, China's aluminum curtain wall industry began to start. The promotion, application and development of aluminum curtain wall in buildings have gone from scratch, from imitation to self-development, from undertaking the construction of small projects to undertaking large-scale engineering projects, from the production of low-grade products to the production of high-tech products, from the construction of low-rise building doors and windows to the construction of high-rise aluminum curtain wall, from the processing of simple low-grade type From relying on imports to contracting projects, aluminum curtain wall system has developed rapidly. In the 1990s, the emergence of new building materials promoted the further development of building aluminum curtain wall. A new type of building curtain wall appeared one after another throughout the country, namely metal curtain wall. At the same time, more and more aluminum curtain wall suppliers began to rise. The so-called metal curtain wall refers to the building curtain wall whose panel material is metal plate. Simply speaking, it is a form of curtain wall in which the glass in the glass curtain wall is replaced by metal plate. However, due to the difference of surface materials, there are great differences between them. Therefore, aluminum curtain wall suppliers should consider them separately in the design and construction process. Due to the excellent processing performance, color diversity and good safety of metal plate, it can fully adapt to the design of various complex shapes, and can arbitrarily increase concave and convex lines, and can process various types of curve lines, which gives architects a huge space to play, and is favored by architects. Therefore, it has obtained rapid development and driven the prosperity of aluminum curtain wall suppliers Up. Among them, the most popular is aluminum curtain wall system.
aluminum curtain wall adopts high-quality building materials and high-strength aluminum alloy plate, the common thickness is 1.5, 2.0, 2.5, 3.0 mm, the model is 3003, and the state is H24. This is also the main material used by most aluminum curtain wall suppliers. Its structure is mainly composed of panel, stiffener and corner code.
aluminum curtain wall system has many advantages. First of all, aluminum curtain wall system corner code can be directly formed by bending and stamping the panel, and can also be riveted on the small side of the panel. The reinforcing rib is connected with the electric welding screw behind the plate surface (the screw is directly welded on the back of the plate surface), which makes it a solid whole, greatly enhances the strength and rigidity of aluminum curtain wall system, and ensures the flatness and anti-seismic ability in long-term use. If sound insulation is required, efficient sound insulation materials can be installed inside the aluminum plate.
Secondly, the surface of aluminum curtain wall is generally pretreated with chromium and then sprayed with fluorocarbon. Vinylidene fluoride resin (kanar500) for fluorocarbon coatings, topcoats and varnishes. Generally, it can be divided into two, three or four coatings. The fluorocarbon coating has excellent corrosion resistance and weather resistance, can resist acid rain, salt spray and various air pollutants, has excellent cold and hot resistance, can resist strong ultraviolet radiation, can maintain long-term color fading, non-powdering and long service life.
Finally, aluminum curtain wall system has unique texture, rich color and durable, and its appearance and shape can be diversified, and it can be perfectly combined with glass curtain wall materials and stone curtain wall materials. Its perfect appearance and excellent quality make it popular with the owners. Its light weight is only one fifth of marble and one third of glass curtain wall. It greatly reduces the load of building structure and foundation, and has low maintenance cost and highly performance price ratio. This is also why more and more aluminum curtain wall suppliers are emerging.
