Rectangular hollow sections are among the strongest hollow steel sections and have the widest range of applications. They are one of the basic building blocks of structural engineering and construction. Durable, strong, and versatile, these sections’ unique shape offers excellent load-bearing capabilities while maintaining a sleek appearance.
Find high-quality steel rectangular sections for every application at Steel Plate & Sections.
Find Out MoreRectangular hollow sections (RHS) are a type of steel section that is rectangular in cross-section but with a hollow center. They are available in a variety of sizes and are made by rolling a steel plate into a rectangular shape and then welding the edges together. This process produces a strong and lightweight section that is also relatively easy to work with.

Key features including high structural strength and load distribution, efficient design and easy fabrication, and corrosion resistance and durability make rectangular hollow sections suitable, if not ideal for, an incredible range of applications.
High strength & load distribution
Superior structural strength is a stand-out feature of rectangular hollow sections. They offer uniform load distribution to improve overall stability and reduce stress concentrations, due to their closed-profile design. These properties make these steel sections ideal for applications in which high resistance to bending and torsion are required, such as bridges, load-bearing frameworks, and support columns.
Efficient design & easy fabrication
Designed for efficiency, these hollow steel sections have a good strength-to-weight ratio that allows for maximum material usage without compromising structural integrity. Fabrication processes such as bolting, cutting, and welding are easier, due to these sections’ consistent geometry. This property makes rectangular hollow sections a popular choice among engineers and manufacturers. These sections can be adapted seamlessly to modular construction or custom frameworks.
Corrosion resistance & durability
Manufactured from high-quality steel alloys, rectangular hollow sections are designed to withstand harsh environmental conditions. Some sections may be treated with galvanisation, power coatings, or other protective coatings to improve their corrosion resistance and increase their lifespan. This durability makes these sections a cost-effective solution for long-term structural applications.
