Right-Angle Square Tube

Right-angle square tube is a hollow metal profile with a square or rectangular cross section and an internal angle accurately approaching 90° (sharp corner radius R≤0.5mm), which is different from the traditional rounded square tube with R≥1.0mm.  It is processed by cold bending forming, hot rolling or extrusion, etc., and is made of carbon steel, stainless steel, etc. through multiple processes. It has stable structure and regular appearance, and is suitable for scenes with high requirements for assembly accuracy and mechanical properties.

Precision is the core competitiveness of Right-angle square tube.  Through cold forming technology, the inner angle radius is compressed to less than 0.3 mm, and the component splicing gap can be controlled to less than 0.1 mm.  This millimeter precision directly reduces on-site machining steps and increases assembly efficiency by 30 to 50 percent.  In a 500-meter super-tower project in Shenzhen, Q345FR fire-resistant square pipe is used as a load-bearing frame. With seamless splicing technology, 70% yield strength retention rate at 600℃ is realized, and the fire resistance limit of 3 hours is achieved with fireproof coating. Compared with the traditional scheme, the consumption of fireproof board is reduced by 30%, and the construction period is shortened by two months.

specification parameter 

Compared with the round square pipe of the same specification, the torsion resistance and bending strength of the sharp corner square pipe are increased by 15% to 20%, and the hollow structure realizes the weight reduction effect of 12% to 30%.  After Q690 high strength square tube is used in the stiffener of deep middle channel steel box girder, the weight of single layer is reduced by 1200 tons. The fatigue life of laser-arc hybrid welding process exceeds 2 million cycles, which is 50% higher than that of traditional welding process. 

Customisation capabilities expand application boundaries.  From high strength steel to aluminum alloy, from laser welding to fluorocarbon spraying, flexible combinations of materials and processes meet the needs of different scenarios.  6061 aluminum alloy square tube is adopted for the base of automobile welding robot, and the accurate installation of guide rail is realized through ±0.1° angle error control. The vibration amplitude of equipment is reduced by 30%. The surface anodization treatment is more suitable for the complex environment of workshop. 

This material, which takes into account both structural strength and aesthetic value, is continuously proving its technical value in the fields of high-rise buildings, bridge engineering, precision machinery and so on.  Millimeter precision, ton weight reduction, scene customization, sharp corner square tube data redefine the performance standards of modern industrial materials. 

Shunchen industry has significant advantages in the field of right-angle square tube products, and the core performance and processing accuracy of the products are excellent.  The inner angle radius of the right angle square tube is less than or equal to 0.3mm, the size tolerance is accurately controlled within ±0.1mm, and the index is superior to the conventional industry standard.  Rich material selection, can produce Q690 high strength steel, Q345FR refractory steel and other products, compared with ordinary products, bending strength increased by 15%-20%, while achieving 12%-30% weight reduction effect.  Laser-arc hybrid welding process is adopted to effectively reduce weld deformation by 70%, and the fatigue life of the product can exceed 2 million cycles.  Support full-specification customization, rely on digital flexible production mode, ensure rapid delivery and strict quality control, and accurately adapt to multi-field application requirements.
