Mild Steel (MS) Square Bars are among the most versatile, reliable, and in-demand structural steel products available today. These bars are an essential choice for engineers, designers, fabricators, and construction professionals across a wide spectrum of industries. At Surya Steel Industries, we manufacture premium-quality MS Square Bars in sizes ranging from 8 mm to 40 mm, all while adhering to strict quality standards and leveraging state-of-the-art rolling technology. Our commitment to precision, performance, and customer satisfaction has helped us become a trusted name across India.

What is an MS Square Bar?

An MS Square Bar is a solid section steel bar with a uniform square cross-section, manufactured using mild steel. It features flat faces and perfectly symmetrical right angles, making it ideal for a wide range of structural and fabrication purposes. These bars are appreciated for their excellent ductility, high tensile strength, easy machinability, and superior weldability.

Unlike round or hexagonal bars, square bars are particularly useful when symmetry and angular precision are required. Their flat surfaces and consistent dimensions help create precise joints, enable better stress distribution, and simplify alignment during fabrication and assembly work. They are highly favored in applications where structural stability, reliable mounting, and solid support are crucial.

At Surya Steel Industries, every square bar is manufactured to meet demanding industry specifications, ensuring top-notch performance, reliability, and ease of use in real-world working conditions.

Applications of MS Square Bars

MS Square Bars are extensively utilized across several industries due to their unique shape and material properties. These applications include but are not limited to:

  • Agricultural Industry: Used in the manufacture of implements, chassis frames, pump housing, and rotating equipment arms.
  • Forging & Engineering: Commonly forged into precision components like U-bolts, flanges, connecting pins, clamps, and threaded fittings.
  • Construction & Scaffolding: Ideal for bracing supports, temporary structural beams, leveling components, couplers, and tension brackets.
  • Automobile & Cycle Units: Extensively used in making suspension mounts, sub-assemblies, seat frames, brackets, and pedal systems.
  • General & Light Fabrication: Used in customized machinery, storage frames, workbenches, platforms, furniture fixtures, modular racks, and PEB structures.

Their unmatched geometry allows for secure placement, straightforward clamping, and a cleaner finish during welding and fabrication. These characteristics make them an optimal choice for high-vibration, load-bearing, or repetitive mechanical motion environments.

MS Square Bar Grades We Offer
