Applications & Usage
Typical uses for this flat bar: base plates, brackets, stiffeners, frames, railings and general fabrication. Section 25 mm: a solid section that can be cut, drilled, machined and welded. Supplied in the bare mill finish, without coating, which keeps cost down where appearance is secondary. Standard lengths: 6m.

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.
