Stainless Steel Octagonal Bar

Stainless steel octagonal bar, also known as octagon stainless rod, is a special solid bar with eight equal sides, normally produced by cold drawing process. It achieves precise across‑flat dimension, high straightness and a smooth uniform surface. Compared with hex bar, octagonal bar offers unique symmetrical geometry for special clamping, connection and decorative mechanical components. Our octagonal stainless bar retains excellent corrosion resistance, ductility and machinability. It can be CNC turned, milled, threaded, welded and polished. We provide a full range of surface options: black pickled, BA bright, polished, No.4 and HL brushed. As a non‑standard shaped bar, it is widely customized for special engineering and decorative projects.
