Square Steel Tube
Hollow square tubing in materials like carbon steel, aluminum, or stainless — available in a range of wall thicknesses and square cross-section sizes so you can get exactly the dimensions your project requires. Square tubing is a versatile structural element, ideal for fabrication, framing, support structures, enclosures, racks, furniture, trailers, and general metal-working projects where strength and rigidity are needed while minimizing weight. Cut-to-size service with no minimum order lets contractors, fabricators, hobbyists, and small shops order just what they need — with local pickup or delivery from their Janesville, WI facility.
