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:
These attributes make SHS a preferred choice for engineering consultants, structural designers, and EPC contractors worldwide.

Choosing the right SHS depends on the structural load, environment, and compliance standards.
Here are the six crucial parameters to evaluate:
Load-Bearing Requirement:
Select S355J2H or YSt 310 for medium to heavy structures requiring higher yield strength.
Thickness vs. Structural Span:
Thicker walls improve buckling resistance and structural rigidity across longer spans.
Corner Geometry:
Tighter corners increase weld area and overall strength in precision assemblies.
Surface Condition:
Outdoor structures benefit from GI and painted coatings for long-term corrosion resistance.
Dimensional Precision:
Architectural applications demand high accuracy in width, flatness, and corner radius.
Compliance & Standards:
Ensure region-specific compliance: Europe (EN 10219), India (IS 4923), or Global (ASTM A500).
Inox Steel India supplies SHS globally with documentation and compliance matching project requirements.
Square Hollow Sections (SHS) serve as essential load-bearing members across structural engineering, fabrication, and architectural projects. SHS provide a clean, uniform geometry with equal strength on all four sides, making them ideal for bending, compression, torsion, and aesthetic framing.
