Constructed from high-tensile cold-reduced mild steel meeting EN10219 standards, our 50mm x 50mm square box sections deliver exceptional strength in a hollow structural section (HSS) profile. These square steel tubing sections come with a mill finish and are stocked in lengths up to 4m.

While the raw mill finish means some minor surface imperfections, these square box sections offer outstanding load-bearing capabilities combined with lightweight rigidity. They are perfect for construction projects, manufacturing applications, and heavy-duty DIY work requiring durable square steel tubing.
