The Mild Steel Round Bar is a versatile and durable solid cylindrical rod crafted from low-carbon steel, designed to meet varied industrial requirements. Manufactured adhering to international standards such as ASTM, ASME, AISI, EN, and IS, these round bars are available in a wide range of grades including IS 2062 GR.A/B, A/SA105, A/SA 350 GR.LF series, A/SA 516 GR.60/65/70, C 45, EN 8, EN 9, P235GH, ASTM A131 GR.A/B/D/E, and AH/DH/EH series among others. The diameter ranges from 3 mm to 350 mm, offering flexibility for diverse applications. Available finishes include Bright, Polish, and Black, ensuring suitability for visual aesthetics and performance needs. These bars are fabricated in multiple forms – Round, Square, Hexagonal (Across Flats), Rectangular, Wire (Coil Form), Wire-mesh, Billet, Ingot, and Forging, making them adaptable for various fabrication projects. The Mild Steel Round Bars are well-suited for structural frameworks, braces, supports, shafting, axles, and marine applications owing to their excellent weldability, machinability, and ductility. They come in two main types based on manufacturing processes: Hot-rolled with a rough surface ideal for general structural applications, and Cold-drawn (bright) bars with a smooth, precise surface finish tailored for precision engineering, automotive parts, and decorative uses. This extensive specification and grade variety combined with multiple form factors make the Mild Steel Round Bar a reliable material choice in construction, manufacturing, and engineering industries.

Mild steel (MS) round bars are solid, cylindrical rods made from low-carbon steel, a versatile and cost-effective material. They are widely used in construction, manufacturing, and general engineering due to their excellent weldability, machinability, and ductility.
Types of mild steel round bars
Mild steel round bars are available in two primary types, differentiated by their manufacturing process and surface finish.
Hot-rolled mild steel round bars: These are formed by heating steel billets and passing them through rollers at high temperatures.
Surface: Rough, scaly surface.
Best for: Structural applications and general-purpose projects where dimensional accuracy is not critical.
Cold-drawn (bright) mild steel round bars: Produced at room temperature, these bars are pulled through a die to achieve a more precise diameter and smoother surface.
Surface: Smooth, bright finish.
Best for: Precision parts in machinery, automotive components, and decorative applications.
