Steel is the backbone of modern infrastructure, and MS Round Bars (Mild Steel Round Bars) are one of the most reliable structural components used across industries. Whether you’re manufacturing auto components, building agricultural tools, or erecting scaffolding systems, the strength, ductility, and dimensional stability of round bars make them indispensable.
At Surya Steel Industries, we’ve been manufacturing high-quality MS round bars since 2005. Based in Mandi Gobindgarh, Punjab, we serve a broad range of industries including agriculture, scaffolding, forging, automobile, engineering, and cycle manufacturing. Our steel bars are crafted with precision, rigorously tested, and trusted by clients across India.
What is an MS Round Bar?
An MS Round Bar is a solid cylindrical bar made from mild steel, a low-carbon alloy that offers excellent weldability, strength, and machinability. Unlike higher carbon steels, mild steel is easier to cut, bend, and fabricate, making it ideal for structural and industrial use.
MS round bars are commonly used in frameworks, shafts, fasteners, and components that require a combination of strength and flexibility. Their widespread use across core industries is a testament to their reliability and versatility.
Sizes and Grades Available
At Surya Steel Industries, we produce round bars in sizes ranging from 8 mm to 40 mm. Whether you’re looking for lightweight structural bars or thick rods for forging applications, we’ve got you covered.
Our product range includes multiple grades:
- Mild Steel (MS) – IS 2062 E250A & E250 BR
- Low & Medium Carbon Series – C20, C22
- High Carbon Series
- EN Series
- SAE/A ISI 1018
These grades are chosen based on application, offering variations in strength, hardness, and ductility to match specific industry requirements.

Applications Across Key Industries
Our MS round bars are not limited to one field—they power productivity across several sectors:
Agriculture Industry
Agricultural tools demand materials that can handle continuous wear and tear. Our round bars are used in tractor linkages, tillers, implements, irrigation components, and other high-impact tools. Their malleability allows for easy welding and shaping, while their strength ensures long-term performance even in rugged field environments.
Scaffolding Industry
In the scaffolding sector, safety and load-bearing capacity are everything. MS round bars are used to manufacture scaffolding clamps, rods, base plates, and cross-braces. Our bars provide the dimensional accuracy and tensile strength necessary to support large-scale construction activities.
Forging & Engineering Industry
Forging demands defect-free, homogeneous steel with excellent machinability. Our bright bar-approved round bars are ideal for components such as gears, crankshafts, valves, and couplings. With smooth surfaces and uniform grain structure, they perform exceptionally well in high-heat forging environments.
Automobile Industry
Precision, strength, and reliability are crucial in automotive manufacturing. Our round bars are used for axles, shafts, suspension parts, fasteners, and brackets. These bars are manufactured to tight tolerances, ensuring compatibility with high-performance machinery.
Cycle Industry
For cycle manufacturers, materials need to be lightweight yet robust. MS round bars from Surya Steel are used in frame tubes, pedal rods, and structural connectors. Their machinability allows for fine-tuned designs, enhancing performance and durability.
Why Choose Surya Steel Industries?
In a market full of rolling mills, Surya Steel Industries stands apart for its fully integrated, technology-driven approach to steel manufacturing. From raw metal processing to the final rolled product, every stage is managed in-house with an obsession for quality and precision.
1. In-House Furnace & Continuous Casting Machine
Unlike many manufacturers who rely on external suppliers for billets, we have our own melting furnace and CCM (Continuous Casting Machine). This gives us complete control over the composition and purity of the liquid metal. We use only high-grade metal scrap and alloying elements to achieve a superior steel mix, ensuring every bar meets exact specifications.
2. Fully Automatic Rolling Mill
Our mill operates with advanced automation, reducing human error and improving consistency. The result? Round bars with flawless surface finish, accurate diameter, and straightness across the full length. The mill also features a long cooling bed, allowing us to offer customized bar lengths as per client demand.
3. On-Site CNC Roll Turning
Precision starts at the foundation. We use CNC machines to turn our rolling mill rolls, ensuring high accuracy in shape and surface finishing. This step is critical for maintaining tight dimensional tolerances during rolling.
4. Internal Testing Facilities
Quality control is not a checkbox—it’s a core principle. We have in-house labs for:
- Chemical Testing with spectrometers to analyze metal composition
- Mechanical Testing with UTM machines to verify strength and elasticity
- Physical Testing using micrometers for dimensional checks during production
Random sampling and full-batch testing ensure that only top-quality products reach our clients.
5. Defect-Free Material & Consistent Bundling
Every bar that leaves our plant is free of inclusions or internal defects. They are bundled with precision—both small and large bundles—making loading, unloading, and inventory management easier for your team.
We’re also installing advanced processes like Vacuum Degassing and EMS (Electromagnetic Stirring) to improve metal homogeneity and purity in the near future.
