PRODUCT DETAILS
Description
Square tube is formed from coil and then ran through a series of dies. It’s welded from the inside to form its shape. Square tubes are generally used for maintenance and structural purposes.
Some examples of square tubing applications would be building construction, railings, and sign posts. They are measured by their outside dimensions and their wall thickness.
Square Tube is available in the following metal types:
Alloy Steel
Mild Stee
Carbon Steel
Stainless Steel
Square tube has similar uses to RHS and is used for both industrial and construction applications. Square section RHS is available in the same thicknesses as RHS and dimensions range from 20 mm x 20 mm to 400 mm x 400 mm.

Application Areas
Steel is widely used in steel structure workshops, bridge frames, main structures of high-rise buildings, and infrastructure construction (such as highways, oil and gas pipelines). Its high strength properties ensure load-bearing stability and seismic performance. In ship manufacturing, steel is used to build hull structures, decks, and internal components. Hot-rolled coils rely on their load-bearing capacity to adapt to harsh environments.
