What is 304 Stainless Steel Round Bar?
304 grade stainless steel round bar (or stainless steel rods) is a solid bar with a circular cross-section and one of the most widely stocked grades of stainless steel in general metalwork and commercial construction.
The material offers excellent corrosion resistance and holds up reliably in environments that involve moisture, chemical exposure, and general wear. It is a practical choice across various applications in construction, fabrication, and general metalwork.
Stainless steel bar in this grade is supplied in a mill finish as standard. It is available in diameters from 3mm to 15mm, and stock lengths run to 1m and 3m. If the dimensions you need fall outside the standard range, contact our team directly to discuss what we can supply.

Common Applications
Stainless steel round bar is widely used across construction, fabrication, and general metalwork. Common uses include gates, railings, and fencing, as well as bolts, nuts, screws, and machined components where corrosion resistance and durability are priorities.
The material also performs well in marine environments, as the grade carries strong resistance to moisture and corrosion, and holds up in demanding conditions.
The bar responds well to welding and machining, so it works across a broad range of project types, from small components to larger fabrication work.
