Following the introduction of CHS, RHS have also become very popular in many forms of engineering solutions and other structural and mechanical applications. This has been greatly assisted by the sections’ inherent flat surfaces making it more economical for joining and other fabrication processes. In this instance, and unlike CHS, the sections only need to be straight-cut (when joining to other flat surfaces) instead of profile cut. Minimal edge preparation is required for joining and welding RHS.

Like CHS, RHS are also aesthetic, possess clean lines, functional, interact less with external environmental effects and are highly desired from an architectural perspective.

Application areas:

• Structural and aesthetic uses in residential construction, commercial and industrial construction, signage, leisure equipment, road furniture, automotive, mechanical, process engineering, materials handling and agricultural.

Precision tube RHS is manufactured and tested to meet the requirements of the following specifications:

• TS21 – Low Carbon ERW Steel Tubing for General Applications
• TS22 – ERW Steel Tubing with Specified Mechanical Properties
• TS30 – Low Carbon ERW Galvatube Steel Tubing for General Applications
• AS1450 – Steel Tubes for Mechanical Purposes
