What Are the Key Advantages of Using Rectangular Hollow Sections in Construction?

At Harding Steel, one of the most versatile and in-demand products we supply is the rectangular hollow section (RHS). Known for its uniform strength, clean aesthetic, and excellent weldability, RHS is a go-to option for builders, fabricators, and engineers who require strong, efficient, and adaptable materials.

RHS steel offers a consistent cross-sectional shape, making it perfect for applications where precision and structural integrity are critical. It’s commonly used in frameworks, load-bearing columns, trusses, trailers, gates, and more. Whether for industrial buildings, modern architecture, or custom fabrication, RHS delivers strength without unnecessary weight.

One of the main reasons builders prefer RHS is its excellent strength-to-weight ratio. This allows for lighter structures without sacrificing performance, which not only reduces material cost but also speeds up installation. Its flat surfaces also make it easier to weld, bolt, and join during construction or fabrication.

At Harding Steel, we stock RHS in a wide range of dimensions and thicknesses to suit any structural or decorative need. Whether you're building from the ground up or reinforcing existing structures, our RHS options offer flexibility and confidence. Each piece is manufactured to meet Australian Standards and is available in galvanised or black steel finishes.

If your project demands reliability, clean lines, and efficiency, rectangular hollow section steel from Harding Steel is a smart investment—built strong, built to perform.
