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.
These characteristics make MS Hollow Sections one of the most widely used materials in general fabrication workshops and light engineering industries.

Choosing the right MS hollow section depends on the fabrication workshop’s specific needs and project budget.
Here are the six crucial parameters to evaluate:
Shape Requirement:
Select SHS for symmetrical frames, RHS for directional bending resistance, or CHS for torsional strength and poles.
Size & Wall Thickness:
Determine the thickness based on the load-bearing need and overall structure weight.
Weldability & Machining:
Mild steel ensures ease of welding, cutting, and drilling with standard workshop tools.
Surface Finish:
Decide between Black (raw), GI (galvanized), Painted, or Oiled based on exposure to moisture.
Dimensional Tolerances:
Crucial for furniture assembly and commercial equipment to ensure parts align perfectly.
Compliance:
Ensure sections meet IS fabrication standards for local infrastructure or industrial projects.
Mild Steel Hollow Sections are extensively used for general fabrication due to their excellent weldability, smooth surfaces, and ease of machining. They are ideal for lightweight structural work and furniture production.
