Home > Hollow Sections > Square Hollow Sections (SHS)
Inox Steel India is a leading manufacturer, supplier, and global exporter of Square Hollow Sections (SHS) conforming to IS 4923 and EN 10219 standards. Our SHS products are trusted by construction companies, fabrication contractors, PEB manufacturers, solar EPC developers, and infrastructure firms for their exceptional strength, dimensional accuracy, durability, and weldability.
Square Hollow Sections are structural tubes with a uniform square profile offering excellent load distribution, high torsional resistance, and superior compression performance. Their clean edges, uniform strength, and aesthetic geometry make SHS an ideal choice for both heavy structural engineering and architectural applications.
At Inox Steel India, we produce SHS in sizes ranging from 25×25 mm to 400×400 mm with wall thicknesses up to 20 mm, using advanced ERW/HFIW and cold-formed technology to ensure consistent structural performance across every batch. All products are made in accordance with IS 4923, EN 10219 S235JRH / S355J2H, ensuring full international compliance.
Backed by ISO-certified processes, strict testing protocols, and high-precision forming lines, we supply SHS to clients across India, UAE, Saudi Arabia, Qatar, Oman, Kenya, South Africa, Germany, UK, USA, and South America with reliable lead times and export-grade packaging.
Square Hollow Sections are produced through a precise forming and welding process designed to deliver accurate dimensions and high strength. Using premium structural-grade steel strips:
1️⃣ Slitting & Strip Preparation – Steel coils are slit to required widths for SHS sizes.
2️⃣ Forming – Rolls shape the strip into a square tube with controlled corner radii.
3️⃣ Welding (ERW/HFIW) – The edges are fused using high-frequency induction, forming a strong weld.
4️⃣ Cold-Forming (EN 10219) – For higher-strength SHS, the tube is precision formed under cold conditions for uniform mechanical properties.
5️⃣ Sizing & Calibration – Achieves exact corner sharpness, width, and thickness tolerances.
6️⃣ Non-Destructive Testing (UT/EC) – Ensures weld soundness and structural integrity.
7️⃣ Cutting & End Finishing – Plain or bevelled ends provided as per customer requirements.
8️⃣ Surface Finish Application – Black, GI, painted, or oiled finish for corrosion resistance.
This controlled manufacturing sequence ensures high-performance SHS suited for demanding structural requirements.
These attributes make SHS a preferred choice for engineering consultants, structural designers, and EPC contractors worldwide.
Grades & Standards (Technical Comparison)
👉 Insert Master Technical Datasheet table here (generated above)
The table gives engineers a clear comparison between IS 4923 SHS and EN 10219 SHS for selecting the right grade based on strength, application, and regional compliance.
1️⃣ Load-Bearing Requirement
Choose S355J2H or YSt 310 for medium to heavy structures requiring higher yield strength.
2️⃣ Thickness vs. Structural Span
Thicker walls improve buckling resistance and structural rigidity.
3️⃣ Corner Geometry
Tighter corners increase weld area and overall strength.
4️⃣ Surface Condition (Black/GI/Painted)
Outdoor structures benefit from GI and painted coatings.
5️⃣ Dimensional Precision Requirements
Architectural applications demand high accuracy in width and flatness.
6️⃣ Compliance with Regional Standards
Europe → EN 10219
India → IS 4923
Africa/Middle East → EN/IS accepted
