Welded steel pipe & tube

Square hollow section

Square hollow section

Square hollow section comes in different sizes, specifications and wall thicknesses.

Its uniformity makes it predictable to use and visually appealing.

It has a high weight-to-strength ratio. It’s easy to bend, and because square steel tubing is inexpensive, it’s cost-effective- even for large projects.

Steel tube is easily recyclable. Many projects take advantage of square steel tubing, including all types of buildings, highway guardrails and signage, support columns, trusses, bridges, heavy equipment, storage systems, and exercise equipment.

A wide range of dimensions, when combined with the appropriate steel grade, ensure that the functionality and cost-efficiency of your structure can be optimised.
