Hot Rolled Dipped Steel Coil Galvanized Coils steel DX051 Q235B z275 Galvanized Steel
Corrugated plate was produced in the United States in the 1930s. In the early 1980s, Wuhan Iron and Steel Group and Baosteel first introduced the production line of color coated steel plates. Since then, China has started to apply domestic color coated profiled plates to industrial buildings, such as Shandong MasterCard factory, national cotton and grain warehouse, and factories in various development zones. With the rapid development of the application technology of the color coated profiled steel sheet, the application scope is expanding and the consumption is increasing.
In the 21st century, China's national economy has developed rapidly and steadily. Color-coated corrugated board has also entered large public buildings from general industrial buildings, such as airport terminals, railway stations, stadiums, concert halls, theatres, and 2008 Olympic venues. The research and development of aluminum-zinc plate, aluminium-magnesium-manganese alloy plate, titanium alloy plate, stainless steel and other materials with more reasonable stress and connection are adopted for the roof, floor and wall of the building, and the construction method is more scientific and the anti-corrosion performance is stronger, which has greatly improved the application technology level of sub-type metal plate.
In terms of plate structure and standard, there are second-generation profiled plate products such as undercut structure, buckle structure and fastener concealed connection; The closed slab building has been widely used; For the coated plate (base plate) of the same profiled plate, the varieties of aluminum-plated plate and zinc-plated aluminum plate are added, and new products such as polyvinylidene fluoride (PVDF) coated plate and high weather-resistant polyester coated plate (HDP) are added to the coated plate; The relevant international "Continuous Hot Galvanized Steel Sheet and Strip", "Color Coated Steel Sheet and Strip", and "Code for Acceptance of Construction Quality of Steel Structures" have been revised in succession.
