Square Tube

Stainless Steel Square Tube

Aluminum Square Tube is one of the most widely used non-ferrous structural materials in industry. It has been widely used in aviation, aerospace, automobile, machinery manufacturing, shipbuilding and chemical industry. With the rapid development of science and technology and industrial economy in recent years, the demand for aluminum tube and aluminum tube is increasing day by day. The production process of aluminum tube generally adopts the production process of ingot heating - extrusion - finishing. For aluminum alloy materials that can be strengthened by heat treatment, quenching and aging treatment should also be carried out. Hard alloy and high magnesium aluminum alloy pipes generally adopt the production process of cold rolling extruded tube billet first, and then stretching out finished products.

welded pipe and square tube .

Square Tubes:

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.

Square Tube, similar to round tube, has efficient shape for multiple-axis loading as it has uniform geometry along two or more cross-sectional axes, and thus uniform strength characteristics. This makes it good choice for columns. It also has excellent resistance to torsion.
