Our S235 mild steel rectangular hollow section (RHS) is supplied in full 7.5m lengths, in sizes from 50x25mm up to 200x100mm and wall thicknesses from 2mm to 6mm. With unequal sides giving greater strength in one direction, RHS is ideal for beams, lintels, load-bearing frames, trailers and structural fabrication, with a 3-5 working day lead time to mainland UK.

Technical Specification

Common Uses

Rectangular hollow section is widely used for structural beams and lintels, load-bearing frames, trailer chassis, gates, railings, support posts, agricultural buildings, workshop fabrication and general construction. Its unequal sides make it the preferred profile where greater strength is needed across one axis.

Rectangular vs Square Box Section

Rectangular hollow section (RHS) has unequal sides and offers greater bending strength in one direction, making it ideal for beams and load-bearing spans. Square box section (SHS) has equal sides and is preferred for general frames, gates and fabrication. Choose RHS where directional strength matters most.

Finish and Protection

Supplied in standard mill finish. The surface may show normal mill scale, handling marks or light surface oxidation, typical for untreated steel. For outdoor or moisture-exposed use, clean, prime and protect with a suitable paint or coating system.

Cutting and Fabrication

S235 rectangular hollow section can be cut, drilled, welded and fabricated using suitable metalworking tools. Cut ends and drilled holes should be protected if used outside or in damp conditions. Always use suitable protective equipment when working steel.

Delivery Information

Lead times are currently 3-5 working days. Delivery is kerbside only and our vehicles do not carry HIAB or lifting equipment - steel must be safely offloaded by the customer on arrival. Sections are supplied in full 7.5m lengths, so suitable delivery access is required.
