Square and rectangular tubes are a general term for square and rectangular tubing. Made from steel strip, they are produced through unpacking, flattening, rolling, and welding into round tubes, which are then rolled into square or rectangular sections. They are a core steel material in the industrial and construction sectors. Materials include Q195, Q235, Q355 carbon steel, and 304, 316 stainless steel, with a complete range of specifications from 10×10mm to 500×500mm in side length and 0.7mm to 30mm in wall thickness. Custom lengths and surface treatments are available upon request.

The Square and rectangular tubes possesses excellent mechanical properties. Its closed-section structure provides high bending and torsional strength, uniform load-bearing capacity, and is more material-efficient and efficient than traditional steel profiles. After hot-dip galvanizing and painting for corrosion protection, it exhibits outstanding corrosion resistance, adapting to complex environments such as humidity and chemical processes, with a long service life and low maintenance costs.

Its applications are wide-ranging, covering multiple fields such as building steel structures, glass curtain walls, machinery manufacturing, automobile chassis, bridge railings, agricultural greenhouses, and furniture decoration. With its advantages of flat appearance, easy processing and installation, and high space utilization, it has become a preferred material that balances practicality and economy.
