Stainless Steel Round Bar
Stainless Steel Round Bars are precision-engineered cylindrical bars used in structural, mechanical, and industrial applications. Known for their exceptional strength, corrosion resistance, and machinability, SS round bars are ideal for demanding environments, including marine, food processing, chemical, and construction sectors.
What is a Stainless Steel Round Bar?
An SS Round Bar is a solid, circular section made from stainless steel alloy. It is known for high tensile strength, excellent resistance to rust and oxidation, and ease of fabrication. These bars can be cold drawn, peeled, polished, centerless ground, or bright finished based on end-use requirements.
At Stellanox, we supply stainless steel round bars in a wide range of grades, sizes, and finishes to meet global engineering and fabrication standards.
