Round Bar

Neptune Alloys is a Leading Round Bar Manufacturer specializing in high performance metal bars for machining, structural and load bearing applications across industrial sectors. We used across industries like automotive, construction and machinery. We produce round bars in various grades including stainless steel, carbon steel, alloy steel, tool steel and aluminum. These bars come in a wide diameter range from 3 mm to 300 mm and can be delivered in standard or custom lengths up to 6 meters. Surface finishes like bright, black, peeled and ground are available to suit specific applications such as shafts, pins, axles and machine parts. Each variant, whether hot rolled or cold drawn, is designed to meet different strength, tolerance and finish requirements. Round bars are widely chosen for their machinability, strength and uniform cross section that simplifies part design and performance in load bearing systems. Our manufacturing process involves hot rolling or cold drawing followed by straightening, polishing, heat treatment or centerless grinding based on customer needs. We ensure every round bar is tested for dimensional accuracy, tensile strength and surface quality in compliance with global standards like ASTM A276, EN 10060 and ISO 286. For high performance uses, we recommend grades like EN24 or 316 stainless steel that offer excellent resistance to fatigue and corrosion.
