Our 40mm x 40mm square box sections are fabricated from high-strength cold-reduced mild steel conforming to EN10219 standards, delivered in a mill finish. These hollow structural sections (HSS) offer outstanding load-bearing capabilities in a square tubular profile. Available in stock lengths up to 4m with free custom cutting to your specified size.

The unfinished mill surface may have some surface oxidation, while cut ends can exhibit minor burrs. However, these robust and economical 40x40mm square steel box sections provide excellent rigidity and are ideal for construction, manufacturing, and demanding DIY projects requiring durable square hollow section tubing.
