Round stainless steel rod

Round Stainless Steel Rod

Stainless steel rods come in various shapes, including flat, hexagonal, square, and round. Each shape is chosen based on the application requirements and mechanical properties needed. When it comes to surface finish, hot-rolled stainless steel round bars tend to have a higher absolute roughness compared to cold-drawn ones. While this isn’t an issue for applications that rely primarily on strength and corrosion resistance, it can be a concern for aesthetic or outdoor uses where a smooth finish is essential. For such cases, cold-drawn stainless steel round bars are preferred due to their improved surface quality and lower roughness.

These bars are available in a wide range of sizes, typically from 5mm to 450mm in radius. Whether you need them for industrial, architectural, or mechanical purposes, we offer a comprehensive selection.
