Rectangular Hollow Sections (RHS) Manufacturer, Supplier & Exporter – IS 4923 / EN 10219
Inox Steel India is a trusted manufacturer, stockist, and global exporter of Rectangular Hollow Sections (RHS) engineered for high-performance structural, architectural, and fabrication applications. Manufactured according to IS 4923 and EN 10219, our RHS products deliver exceptional strength, dimensional accuracy, flat-sided uniformity, and superior weldability for modern construction and engineering requirements.
RHS is widely preferred for structures that demand strong axial load capacity, excellent bending resistance, and easy integration into fabricated assemblies. The flat surfaces and optimized corner radii of RHS make it particularly suitable for PEB structures, solar mounting systems, heavy industrial frameworks, and civil infrastructure.
With advanced ERW/HFIW forming lines and cold-forming capabilities, Inox Steel India produces RHS in sizes ranging from 40×20 mm to 500×300 mm with wall thicknesses up to 20 mm. Our ISO-certified production, strict testing protocols, and comprehensive traceability ensure consistent quality for domestic and international customers across the Middle East, Africa, Europe, and the Americas.
Rectangular Hollow Sections are produced through a precise shaping and welding process that ensures strength, stability, and uniformity.
These properties make RHS the backbone of many engineering, solar, and civil projects worldwide.

Choosing the right RHS depends on the structural load orientation, environment, and compliance standards.
Here are the five crucial parameters to evaluate:
Load Orientation:
Choose RHS where one direction requires higher bending resistance and deflection control.
Corner Profile & Flatness:
Flat surfaces are critical for precision bolting, welding, and aesthetic finishing in exposed designs.
Thickness vs. Span Length:
Thicker RHS performs better for long-span or high-moment structures to prevent buckling.
Service Environment:
GI and Painted RHS are recommended for outdoor installations and corrosive industrial atmospheres.
Regional Compliance:
Middle East and EU projects typically prefer EN 10219, while Indian projects utilize IS 4923.
Rectangular Hollow Sections (RHS) are widely used across industrial, civil, and architectural projects due to their strong directional load capacity, flat-sided geometry, and structural efficiency. Each grade and standard delivers unique performance benefits depending on the application environment.
