FAQ

What is Circular Hollow Section?

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.

In hot rolling, steel is heated to a high temperature before being passed through rollers to create a tubular shape with precise dimensions. On the other hand, cold forming shapes the steel at room temperature, allowing for tighter tolerances and smoother finishes.

Both methods ensure that CHS steel meets the demands of construction applications, offering exceptional structural integrity and durability. These processes enhance its strength, uniformity, and resistance to external forces, making CHS sections a popular choice for load-bearing elements and architectural designs.

How to measure the diameter of a circular hollow section?

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.

Do you deliver CHS across the UK?

Yes. We provide reliable nationwide delivery for both individual steel sections and bulk project orders.
