The Stainless Steel Round Bar (also known as Stainless Rod or Bar Stock) is the most versatile raw material in the metalworking industry. Available in premium 304 (A2) and 316 (A4) grades, our Stainless Steel Round Bar features a smooth, uniform surface finish and precise dimensional tolerance, making it the ideal starting point for machining shafts, fasteners, fasteners, and architectural structural components.
Product Overview: We supply Stainless Steel Round Bar in two primary finishes: Cold Drawn (for smaller diameters with high precision) and Peeled/Turned (for larger diameters). Whether you are manufacturing automotive axles or welding bespoke kitchen furniture, our solid rods offer exceptional machinability and corrosion resistance.

Engineering Insight: 304 vs 316 Stainless Steel
Choosing the right alloy for your Stainless Steel Round Bar is critical for project longevity:
- Grade 304 (A2): The “workhorse” grade. It offers excellent strength and corrosion resistance for indoor applications, food processing equipment, and general machining. It is more cost-effective.
- Grade 316 (A4): Contains added Molybdenum. This gives the bar superior resistance to chlorides and acids. If your rod will be used on a boat, a seaside balustrade, or in a chemical plant, you must use Grade 316 to prevent pitting corrosion.

Applications
Our bars are widely used in:
- Machining: Production of bolts, nuts, screws, and custom bushings.
- Construction: Concrete reinforcement (Rebar) and architectural handrails.
- Marine: Propeller shafts and rigging fittings.
Frequently Asked Questions (FAQ)
Q: What is the length of the bar?
A: Our standard stock length is 3 meters or 6 meters. However, we offer a free cutting service to supply the exact length your project requires.
Q: Is the surface polished?
A: Cold drawn bars have a naturally smooth, bright grey finish. We can also provide “Centerless Ground” or “Polished” bars (Mirror Finish) for decorative applications upon request.
