High Efficiency
The cross-sectional shape of rectangular steel pipes is rectangular, which provides greater strength and stiffness and is suitable for structures that require high pressure and load, such as bridges and large buildings. Its structural stability is superior to other shapes of steel pipes
Compared to solid steel of the same strength, rectangular steel pipes are lighter in weight. This makes it more convenient for construction and transportation, reducing construction costs and labor demand.
Rectangular steel pipes are made through cold bending or hot rolling processes, with a smooth surface and high compressive strength. This makes it widely used in fields such as construction, machinery manufacturing, and automotive industry
Rectangular steel pipes are made of soft material, easy to process, and can be processed through cutting, welding, cold bending, and other techniques. This good processability provides greater design freedom for various construction and manufacturing projects
Rectangular steel pipes can be treated with advanced coating and plating techniques to improve their corrosion resistance. This makes rectangular steel pipes have a longer service life in corrosive environments such as marine environments and chemical industries
Compared with wide flange H-beams and circular steel pipes of the same weight or cross-sectional height, the bending stiffness of rectangular steel pipes in both axial directions is 1.3 times that of circular steel pipes, which is close to the bending stiffness of H-beams in the strong axial direction.
In our life and industry, rectangular tubes are widely used in large buildings such as Hong Kong-Zhuhai-Macao Bridge, Yuantai Derun provide high quality rectangular tube .
Rectangular tube is widely used in building structures because of its excellent yield strength, tensile strength, elongation and corrosion resistance.Yuantai Derun supplied rectangular tube for Cairo Administrative CBD, Egypt
In these high-tech fields, the high-temperature stability and mechanical properties of rectangular tube have been fully utilized.Yuantai Derun's early rectangular tubes were supplied to agricultural machinery factories in Henan, China。
Rectangular tube are also widely used in the fields of Offshore photovoltaic bracket.
