Round bars are integral to modern engineering and construction projects. From shafts to support structures, round bars bring strength, versatility, and efficiency. In this guide, we break down everything you need to know about round bars — their types, uses, and technical specs — with insights from a leading round bars manufacturer in India.

What Are Round Bars?

Round bars are long cylindrical metal rods commonly used in fabrication and industrial applications. Manufactured using various metals such as mild steel, stainless steel, carbon steel, and alloy steel, these bars offer high strength and machinability.

Common Specifications of Round Bars

Property	Specification
Diameter Range	6 mm – 200 mm
Length	6 meters (standard) or customized
Tolerance	h9 to h11 (varies by grade & application)
Finish	Black, Bright, Peeled, Ground
Standards	ASTM A276, AISI, EN8, IS 2062, DIN, JIS

Applications of Round Bars

Round bars are used across industries due to their adaptability and mechanical strength. Common applications include:

• Construction: Reinforcements, balustrades, railings
• Automotive: Shafts, gears, axles, fasteners
• Machinery: Bearings, pins, rollers, flanges
• Oil & Gas: Pipelines, structural supports
• Fabrication: Frames, tool handles, brackets

Types of Round Bars

Type	Description
Mild Steel (MS)	Economical, ductile, and easy to weld; used in general fabrication
Stainless Steel	Corrosion-resistant; used in medical, food, and marine industries
Carbon Steel	High strength and hardness; suitable for mechanical parts
Alloy Steel	Enhanced wear, corrosion, and heat resistance
Bright Bars	Precisely drawn with a smooth surface; used in precision engineering
