Explain the application areas of non-standard square rectangular tube products
Non standard square rectangular pipes are mainly used in the construction of large venues, such as airports, sports stadiums, stations, etc., as the main steel frame, walls, etc., and in the construction of civil steel structure residential buildings.
In addition, it is used as a base and bracket for equipment in the mechanical industry, for the modification of vehicles as beams and large trucks, for the body of agricultural tricycles, and for welding various frames in civilian use.
The main applications of high-frequency non-standard square and rectangular tube products in the construction industry are high-frequency welded square and rectangular tubes for structural use and cold-formed steel for building use, with square and rectangular tubes accounting for more than 50% of the usage.
From the perspectives of structural mechanics and economics, the combination of rectangular pipes and H-beams is the best combination for the construction industry, which can achieve the industrialization of industrial plants and residential buildings.
In developed countries, the construction industry is the largest user of square tubes, accounting for 50% of the total steel production. Square tubes used in the construction industry account for more than 70% of the total square tubes. The main application of square tube products in the construction industry is square tubes used in building structures.
According to the statistics of the Non standard Rectangular Tube Domestic Building Metal Structure Association, the steel used in steel structures in China has exceeded 8 million tons. About 30 million square meters of industrial and civil steel structures are newly built each year, and 6-7 million tons of various steel materials are used for engineering construction every month, including 300000 tons of cold-formed welded rectangular tubes.
