Product Description
The 75 x 50 x 5mm - 7.5m Mild Steel Rectangular Box Hollow Section is a dependable structural steel solution engineered for strength, stability, and efficiency in a variety of applications. Manufactured from S235JR grade mild steel and compliant with BS EN 10219 standards, this rectangular hollow section (RHS) delivers reliable performance in load-bearing environments.
Thanks to its 75mm x 50mm rectangular profile and 5mm wall thickness, this section is ideal for frameworks, construction supports, and general engineering use. Its shape offers enhanced directional strength—particularly suited for vertical or horizontal applications requiring high resistance to bending or buckling. The 7.5m length provides flexibility for long spans or custom fabrication with minimal joins.
Whether you're working on structural frameworks, transport trailers, industrial racking, or architectural metalwork, this RHS delivers practical strength while maintaining manageable weight and machinability.

FAQ
Is this 75 x 50 x 5mm rectangular hollow section suitable for welding?
Yes, this RHS is made from S235JR mild steel, which has excellent weldability. It's compatible with MIG, TIG, and stick welding techniques. Clean the surface of mill scale and contaminants before welding for best results, especially in load-critical structures.
Can I cut this RHS to shorter lengths on-site?
Absolutely. This hollow section can be easily cut using band saws, chop saws, or angle grinders equipped with metal cutting discs. For clean, burr-free cuts, especially for joining or painting, use a saw with a suitable TPI (teeth per inch) blade.
What is the approximate weight of a 7.5m length?
A 75 x 50 x 5mm RHS weighs approximately 10.57 kg per metre. A full 7.5m length would weigh around 79.3 kg. This figure is useful for load planning, handling, and delivery logistics.
Can I drill or tap into the 5mm wall?
Yes, the 5mm thickness offers good material for drilling and light tapping. For tapping threads, use appropriate cutting oil and HSS drill bits to maintain precision and avoid damaging tools or material.
Is this RHS galvanised or bare steel?
This product is supplied in bare mild steel as standard. If your project requires corrosion resistance for external or high-humidity environments, galvanising or powder coating is recommended post-fabrication.
