CHS was the first and still the most common form of hollow section. It is used in a multitude of applications including building construction and other structural and mechanical areas. CHS possess inherent traits such as aesthetics, functionality and engineering efficiencies which have been embraced for decades.

From an architectural perspective the constant clean lines provide a very smooth surface appearance which is expressly exploited in many high-profile applications. The lack of protruding edges on these fully closed sections assists in reduced exposure effects to any environment and also in increased cleanliness from dust and other material build-up.

Application areas:

• Structural and foundation uses in residential, commercial and industrial construction,
  signage, leisure equipment, road furniture, transport industries, mechanical, heavy engineering, mining and resources, process engineering, materials handling, agricultural, fencing and some limited low pressure fluid conveyancing applications.

Structural CHS is manufactured and tested to meet the requirements of the following specifications:

• AS 1163 – Structural steel hollow sections.
