CHS Steel FAQs

Below are the most common questions sent to our team about CHS steel.

What is CHS in Steel?

CHS stands for Circular Hollow Section, a type of structural steel characterised by its circular cross-section. Known for its strength, aesthetic appeal, and versatility, CHS steel is widely used in construction for applications such as columns, trusses, and architectural features.

Its uniform shape offers excellent resistance to torsion and bending, making it ideal for projects where strength and durability are critical. Whether for structural use or design elements, CHS steel provides a reliable and efficient solution for modern construction needs.
How are circular hollow sections made?

Circular Hollow Sections (CHS) are manufactured through a process called hot rolling or cold forming.

Hot rolled: Steel is heated to a high temperature and then passed through rollers to create a tubular shape. Hot-rolled CHS steel is smooth and features no join marks.
Cold forming: Steel plates are heated and bent into a cylindrical shape then joined shut via welding. Cold-formed CHS steel cools at room temperature, allowing for tighter tolerances and smoother finishes.
How to measure the diameter of a CHS Steel?

To measure the diameter of a Circular Hollow Section (CHS), use a tape measure or calliper to determine the outer diameter (OD) of the pipe. Place the measuring tool across the widest part of the section, ensuring it spans the circular cross-section fully for an accurate result.

Accurate measurement of the diameter is essential in construction to ensure the CHS meets project specifications and fits seamlessly into the structural design. For precise results, especially on large-scale projects, consider using specialist tools or consulting a structural professional.
What Are The Benefits of CHS Steel?
There are some core benefits you will find when choosing CHS steel over other types of structural steel, including:
- Excellent load-bearing capabilities
- Unique shape is aesthetically pleasing
- Easier to bend than other cold-formed hollow sections
- High torsion resistance
- Suitable for exposure to high wind and water currents due to smooth shape
What is the Difference Between CHS and RHS Steel?
CHS steel and RHS (Rectangular Hollow Sections) steel are both types of ‘hollow section’ steel beam, used in structural construction. There are some further differences between the two, including:
- RHS: Rectangular shape that is flexible across projects. Commonly used as posts with plates at either end, or with beams coming into either side.
- CHS: Cylindrical shape that is commonly used as columns. Smaller CHS steel sections can be used as spacers between beams or as bracing for larger structures.
