Structural Tubes, also known as hollow sections, are used as a structural element in buildings, bridges and other structures, and in a wide variety of manufactured products. It’s produced in round, square and rectangular shapes in a broad range of sizes and gauges.
Rectangular Tubes are commonly used in welded steel frames where members experience loading in multiple directions.

It is widely used in aviation, automobile, shipbuilding, mining machinery, agricultural machinery, construction, textile and boiler manufacturing. Cold drawing, welding, extrusion and hot rolling are the methods of producing special-shaped tubes. Compared with the circular tube, the special-shaped tube generally has larger moment of inertia and section modulus, and has greater bending and torsion resistance, which can greatly reduce the weight of the structure and save steel. 1 ASTM A500 Cold Formed Welded and Seamless Carbon Steel Structural Tubing in Rounds and Shapes 2 ASTM A501 Hot-Formed Welded and Seamless Carbon Steel Structural Tubing 3 ASTM A511 Seamless Staniless Steel Mechanical Tubing 4 ASTM A513 Electric-Resistance-Welded Carbon and Alloy Steel Mechanical Tubing 5 ASTM A554 Welded Stainless Steel Mechanical Tubing 6 ASTM A618 Hot-Formed Welded and Seamless High-Strength Low-Alloy Structural Tubing 7 EN 10210 Hot Finished Structural Hollow Section of Non-alloy and Fine Grain Structural Steels 8 EN 10219 Cold Formed Welded Structural Hollow Sections of Non-alloy and Fine Grain Steel 9 EN 10305-5 Steel Tubes for Precision Applications-Welded and Cold Sized Square and Rectangular Tubes 10 GB/T 3094 Cold Drawn Shaped Steel Tubes 11 GB/T 34201 Seamless Hot-Rolled Square and Rectangular Steel Tubes for Structure 12 JIS G3446 Stainless Steel Pipe for Machine and Structural Purposes
They offer strength and are used in construction and engineering applications for their load-bearing capacity and resistance to bending and torsion force.
