Home > Round Bars
Round Bars are among the most widely used raw materials in engineering, fabrication, machining, and industrial manufacturing. Produced in stainless steel, carbon steel, alloy steel, tool steel, duplex, nickel alloys, copper alloys and titanium, round bars provide stable mechanical strength, excellent machinability, and uniform grain structure.
Unlike flat or square bars, round bars deliver:
Industries rely on round bars for machined components, valves, fasteners, shafts, pump parts, aerospace hardware, oil & gas components, and marine-grade equipment due to their strength, dimensional accuracy, and consistent metallurgical properties.
Round Bars are produced through three main processes, selected based on end-use requirement:
Manufactured by hot rolling billets at high temperature.
Advantages:
Produced via cold drawing and centreless grinding.
Benefits:
Manufactured from forged billets or ingots.
Why engineers choose forged bars:
Machined to remove scale and surface imperfections.
Applications:
With over a decade of experience and multi-material capability — from Stainless Steel to Carbon, Alloy, Duplex, and Nickel Alloys with Product Pipes, Tubes, Bars we serve the world’s most demanding industries with trust, traceability, and timely delivery.
