Applications & Usage

This medium-duty Steel round bar is commonly specified for furniture manufacturing, enclosures, brackets, and general fabrication. The 12mm diameter provides excellent strength-to-weight ratio while maintaining workability. The natural mill finish provides a cost-effective solution for applications where aesthetics are secondary. Available in standard lengths of 6m, this profile can be easily cut, drilled, and welded to suit your specific requirements.

SAE 1010–1060 and the ST 37-2 to ST 60 designations are supplied to chemical composition; their mechanical properties depend on the delivery condition and are confirmed per order. ASTM A615 is a reinforcing-bar standard, quoted on request. Impact values apply from 6 mm; for thin sections (EN below 3 mm, ASTM below 8 mm) the elongation requirement follows separate rules and is given in the test certificate. ASTM A572 values are for Grade 50; please confirm the grade in your enquiry.
