Home > Hollow Sections > Construction & Building Frames
Inox Steel India supplies a complete range of structural hollow sections (SHS, RHS, CHS) engineered for modern construction and building frame systems, where strength, rigidity, durability, and clean architectural aesthetics are essential. Hollow structural sections are now the preferred choice for engineers and architects because they offer superior load-bearing capacity, excellent torsional strength, uniform stress distribution, and enhanced design flexibility compared to traditional open sections.
Building frames require structural members capable of handling vertical, horizontal, and dynamic loads without compromising stability or safety. The closed geometry of hollow sections makes them inherently resistant to bending, buckling, and torsional deformation—making them ideal for columns, beams, trusses, façades, mezzanines, staircases, walkways, rafters, pylons, and industrial building frameworks.
Inox Steel India provides construction-grade hollow sections in multiple global standards:
These sections are widely used in commercial buildings, PEB structures, industrial plants, high-rise projects, infrastructure, stadiums, airports, and architectural steel frameworks across India, GCC, Africa, Europe, and Southeast Asia.
Hollow sections not only offer structural superiority but also enable lightweight, economical, and aesthetically refined designs—reducing fabrication time, improving joint efficiency, and increasing the lifespan of building frameworks.
Hollow sections are fundamental to modern structural engineering due to their high stiffness, predictable bending behavior, and superior load-carrying capacity. Below is the structured application breakdown for construction and building frames.
🔹 1. Column & Vertical Load Members
Hollow sections are ideal for building columns because of their excellent compression resistance and uniform load distribution.
Preferred Sections:
Suitable Standards:
EN 10210 (S355J2H) • ASTM A500 Grade C/D • IS 4923 YSt 310/355
🔹 2. Beams, Rafters & Girders
Used for primary and secondary framing in PEBs, warehouses, malls, and factories.
Benefits:
High bending strength • Excellent torsional resistance • Clean architectural lines
Preferred Sections:
RHS/SHS (medium to heavy thickness)
🔹 3. Trusses & Space Frames
Lightweight yet strong, hollow sections offer optimum tension–compression performance.
Used in:
Preferred Sections: CHS / RHS
🔹 4. Staircase, Mezzanine & Platform Frames
Hollow sections provide mechanical stability and aesthetic appeal for:
🔹 5. Façade Frames & Architectural Steel
Hollow sections create sleek, minimalistic, and strong support systems for:
Preferred Sections: RHS (due to flat surfaces for cladding attachment)
🔹 6. PEB (Pre-Engineered Building) Frame Systems
Used for columns, rafters, bracings, tie beams, and connections.
Why HSS?
🔹 7. Outdoor Structures & Industrial Utilities
Hollow sections are used for:
GI / HDG hollow sections recommended for corrosion-prone zones.
