Color steel profiled sheet is a new type of building material that has been developed internationally in recent years. It has light weight, high strength, beautiful and durable, and has a service life of 15-20 years. It has good earthquake resistance, quick and easy construction, high heat reflection and low heat emission. It has obvious characteristics such as heat insulation effect, and is suitable for roof panels, wall panels and floor panels of industrial and civil buildings, especially for large-span workshops, grain storages, warehouses, etc. First, the characteristics of color steel profiled board: 1. The color steel plate is beautiful and novel in appearance, rich in color, strong in decoration, flexible in combination, and can express different architectural styles; 2, color steel plate is light weight (6~10kg/m2) high strength (yield strength 250~550MPa), good skin stiffness and good waterproof performance of waterproof agent; 3, the quality of factory products is high 4. The color steel plate is easy to construct and install, reducing the installation and transportation workload and shortening the construction period; 5. The color steel plate is an environmentally-friendly building material, which can be recycled and used to promote the application of the profiled steel plate in line with the policy of sustainable development of the national economy; 6. The price of the single material of the color steel profiled plate is relatively high, and the durability is poor compared with the concrete or masonry enclosure material. Color steel profile board Second, the application development of China's color steel profiled panels: Color steel profiled panels were produced in the United States in the 1930s. In the early 1980s, WISCO and Baosteel first introduced color-coated steel sheet production lines. Since then, China has begun to apply domestically-made color-coated pressure-sensitive sheets to industrial buildings such as MasterCard, National Cotton and Food. Warehouses, factories in various development zones, etc. With the rapid development of application technology of color-coated profiled steel sheets, the application range is expanding and the dosage is increasing. In the 21st century, China's national economy has developed at a high speed and steadily. Color-coated steel plates have also entered large-scale public buildings from general industrial buildings, such as airport terminals, railway stations, stadiums, concert halls, grand theatres, and the 2008 Olympic Games. Venue. The roof, floor and wall of the building adopt a more reasonable shape and connection. The construction method is more scientific and seems to be a more powerful aluminum-zinc plate, aluminum-magnesium-manganese alloy plate, titanium alloy plate, stainless steel, etc. The research and development has greatly improved the application technology level of the sub-type metal plates. In terms of plate structure and standard, second-generation profiled products such as undercut structure, snap-fit ​​structure and hidden connection of fasteners have appeared; closed-type slabs have mature applications; coatings of colleague profiled panels The plate (substrate) has increased the variety of aluminized plate and galvanized aluminum plate. The coated plate has added new products such as polyvinylidene fluoride (PVDF) coated plate and high weather resistant polyester coated plate (HDP); relevant international "continuous hot plating" Zinc steel plate and steel strip, "color coated steel plate and steel strip", "Steel structure engineering construction quality acceptance specification" and so on have been revised.
