Rectangular Hollow Sections - FAQs

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

What does RHS stand for in steel?

RHS stands for Rectangular Hollow Section, a type of structural steel with a rectangular cross-section. This design offers greater flexibility for load distribution, making it suitable for beams, columns, and bracing applications.

RHS steel is widely used in construction due to its excellent strength-to-weight ratio and ease of fabrication. Its rectangular profile is particularly advantageous for structures requiring high stability and efficient space utilisation.
What is RHS steel used for?

RHS steel is widely used in construction for its strength, versatility, and efficient design. Common applications include beams, columns, and bracing in structural frameworks, where its rectangular shape provides excellent load distribution and stability.
How are RHS sections measured?

Rectangular Hollow Sections are measured by their external width, height, wall thickness, and length. The rectangular profile requires precise measurement of both width and height, recorded in millimetres, along with wall thickness for accurate specifications. Tools like callipers or tape measures are commonly used to ensure precision.

For a comprehensive overview of sizes and weights, refer to the RHS dimension table available on this page. This resource provides detailed insights to help you select the right specifications for your construction project.
How to calculate the rectangular hollow section?

To calculate a Rectangular Hollow Section (RHS), measure its external width, height, and wall thickness, all in millimetres. These values are essential for determining the cross-sectional area and weight, which are critical for structural analysis in construction projects.

For precise calculations, you can apply standard formulas to assess additional properties such as bending strength or moment of inertia. These measurements ensure the RHS meets the specific demands of your project and supports accurate planning.
