Inox Steel India is a leading manufacturer and global supplier of Mild Steel Hollow Sections (MS HS) designed for reliable and cost-efficient general fabrication work. Our product range includes Square Hollow Sections (SHS), Rectangular Hollow Sections (RHS), and Circular Hollow Sections (CHS) manufactured as per IS 4923, IS 3601, and IS 1161 standards. These hollow sections are widely used for furniture frames, fabrication assemblies, support structures, machine components, store fixtures, gates, railings, and light engineering work where weldability, machinability, and dimensional accuracy are essential.
Mild Steel Hollow Sections offer smooth surfaces, uniform wall thickness, and excellent forming characteristics that make them easy to cut, bend, drill, weld, and assemble. Their low-carbon composition ensures minimal cracking during welding, while controlled manufacturing processes deliver straightness, squareness, and clean corner geometry required for fabrication workshops and commercial equipment manufacturers.
Inox Steel India produces MS Hollow Sections in a wide range of sizes—from 25×25 mm to 300×300 mm (SHS), 40×20 mm to 400×200 mm (RHS), and 21.3 mm to 508 mm OD (CHS)—to support fabrication companies, engineering contractors, and industrial OEMs. Our facilities include high-frequency induction welding lines, precision roll-forming mills, and ISO-certified testing laboratories, ensuring consistent performance and dependable fabrication quality for every batch we supply.
With exports to the Middle East, Africa, Europe, and South America, we provide MS Hollow Sections that meet project specifications, budget expectations, and delivery deadlines for fabrication and light structural applications.
Mild Steel Hollow Sections follow a controlled roll-forming and welding process that ensures uniformity, straightness, and high fabrication efficiency:
1️⃣ Slit Coil Preparation
Mild steel coils are slit to accurate widths based on SHS, RHS, or CHS dimensions.
2️⃣ Forming via Rolls
The strip passes through forming rolls that gradually shape it into square, rectangular, or circular profiles while maintaining corner accuracy and surface smoothness.
3️⃣ High-Frequency Induction Welding (HFIW)
Edges are welded under high-frequency heat, creating a strong and seamless longitudinal joint.
4️⃣ Sizing & Straightening
Final shaping is done to meet dimensional tolerances for width, height, OD, wall thickness, corner radius, and straightness.
5️⃣ Non-Destructive Testing (UT/EC)
Weld seams undergo inspection for internal defects to ensure safety during fabrication.
6️⃣ Cutting to Length
Sections are cut into standard or customized lengths suitable for workshop operations.
7️⃣ Surface Finishing
Black, oiled, painted, or galvanized finishes added depending on application needs.
This manufacturing sequence ensures that MS Hollow Sections deliver predictable performance in bending, welding, cutting, drilling, and assembly.
