Mild Steel Square Bar

Grade: s275 JR

Mild steel square bars, also known as steel squares, box bars, and solid squares are high-strength steel bars used in a variety of construction applications. They have a square cross-section and are made from low-carbon steel. They are the perfect solution for the construction of frames, machinery, fencing applications, and structural steelworks. We offer our steel squares in a wide range of measurements from 10-50mm widths, and a cut to size to your exact required measurements for the length. Mild steel square bars have incredible strength and durability, great practical properties and are very workable, malleable and pliable due to their low carbon content. Mild steel has many attractive properties which make it perfect for construction such as its recyclability, cost-effectiveness, ease of fabrication and capacity to withstand substantial loads. We stock a range of measurements for your mild steel square bars ranging from 10mm, 20mm, 30mm, 40mm, and 50mm in width. We understand that you may require specific length measurements for your steel squares, which is why we offer a cut-to-size for the length of your steel. Simply input the length required when checking out, and we will cut your steel squares to length in-house.
