MS Round Bars: Types, Sizes & Key Industrial Applications

21st Mar 2025

In the world of construction and manufacturing, materials play a crucial role—and MS round bars are among the most relied-upon components. Known for their strength, reliability, and versatility, mild steel round bars are commonly used in fabricating machinery, reinforcing structures, and supporting various industrial applications. Their consistent performance has made them a preferred choice for engineers, builders, and fabricators across India.

Introduction to MS Round Bars

MS round bars are long, cylindrical bars made of mild steel, a low-carbon alloy known for its strength and flexibility. These bars are widely used across industries—from construction and automotive to manufacturing and fabrication—because of their ease of machining, weldability, and cost-effectiveness.

Kesar Steel supplies IS-standard MS round bars in a variety of sizes and thicknesses, suitable for fabrication, industrial machinery, and construction work.

Properties of Mild Steel Round Bars

Mild steel round bars are valued not just for their affordability but for a balanced mix of properties that make them ideal for structural and industrial use:

High Ductility: MS bars can bend without breaking, which is vital in earthquake zones or applications needing flexibility.
Good Weldability: These bars are easy to weld, cut, or bend into different shapes—making fabrication smooth and efficient.
Strength & Toughness: Despite being low-carbon, mild steel offers great tensile strength for moderate to heavy-duty applications.
Corrosion Resistance: While mild steel itself isn’t stainless, coatings or paints can significantly increase its durability in outdoor use.

Common Types of MS Round Bars

Different projects require different types of round bars. At Kesar Steel, we offer a variety of options, including:

Hot Rolled MS Round Bars: These are manufactured at high temperatures and have a rougher surface, perfect for structural applications.
Cold Drawn or Bright Bars: These offer better dimensional accuracy and surface finish—ideal for automotive parts and precision components.

Choosing the right type depends on whether you're using the bar for strength, surface finish, or fabrication ease.

MS Round Bar Sizes & Weight Chart

MS round bars come in a range of diameters and lengths to suit different construction and fabrication needs. Common diameters range from 6mm to 80mm, though custom sizes are available upon request.

Knowing the MS round bar weight is important for design and procurement. While many use a standard chart, engineers often refer to the mild steel round bar weight calculation formula:

Weight (kg) = (π/4 × D²) × L × 0.00785,
where D = diameter in mm, L = length in meters, and 0.00785 is the density of mild steel.

Having access to a mild steel round bar weight chart ensures accurate estimation and efficient material handling.

Industrial Applications of MS Round Bars

The flexibility of MS round bars means they’re used in almost every industry. Some key applications include:

Construction: Reinforcement in RCC, columns, or steel frames.
Fabrication: Ideal for gates, grills, and fencing structures.
Machinery: Used in shafts, axles, and mechanical components.
Automotive: Bright MS bars are perfect for gear shafts, bolts, and bushings.
Furniture Manufacturing: Offers a sturdy yet affordable framework solution.

If you’re looking to build something that lasts, mild steel round bars provide a balance of strength, affordability, and workability.

How to Choose the Right MS Round Bar

Choosing the right bar isn't just about diameter. You should also consider:

Purpose of Use: Structural use may need thicker bars, while fabrication needs precision.
Standard or Custom Sizes: Refer to MS round bar standard sizes or request a custom order from Kesar Steel.
Location: If you’re working in a coastal or humid region, consider protective coatings for better corrosion resistance.
Supplier Reliability: Always buy from a reputed MS round bar manufacturer to ensure consistent quality.

A reliable supplier also helps you understand MS round bar price per kg and offers transparent pricing.
