Home > Hollow Sections > Automotive & Transport
Inox Steel India supplies precision-engineered hollow sections (SHS, RHS, CHS) designed for the demanding requirements of the automotive, commercial vehicle, transport infrastructure, logistics equipment, and mobility engineering sectors. These industries require structural members that offer high strength-to-weight ratio, predictable impact behaviour, resistance to dynamic loading, and easy fabrication—making hollow sections the preferred choice for vehicle frames and transport structures.
Automotive and transport applications operate under continuous vibration, varying load cycles, torsional stress, and exposure to environmental conditions. Hollow structural sections provide superior mechanical stability, low weight, weldability, and dimensional uniformity, enabling manufacturers to produce strong yet lightweight designs that improve efficiency, safety, and operational performance.
Inox Steel India supports OEMs, auto body builders, transport equipment manufacturers, trailer fabricators, agricultural vehicle makers, and mobility infrastructure developers with hollow sections manufactured in:
These sections are widely used across the automotive and transport industry in applications such as:
Hollow sections improve design flexibility, reduce overall weight, enhance crashworthiness, and increase durability—making them indispensable in modern mobility and transport engineering.
Inox Steel India reliably supplies auto-grade and transport-grade hollow structural sections to manufacturers across India, GCC, Africa, Europe & Southeast Asia with precise tolerances, strict mechanical properties, and superior weld seam integrity.
| Application | Recommended Standard | Strength Level | Benefit |
|---|---|---|---|
| Vehicle chassis | ASTM A500 Grade C/D | High | Strong, consistent, dimensionally precise |
| Bus body fabrication | IS 4923 / EN 10219 | Medium–High | Lightweight + weld-friendly |
| Trailers & cargo structures | EN 10210 / EN 10219 | High | Good bending/torsion resistance |
| Interior seating frames | IS 4923 (thin gauge) | Medium | Lightweight + formable |
| ROPS / safety frames | IS 1161 CHS | High | Uniform stress distribution |
| Outdoor transport frames | GI / HDG HSS | Medium–High | Corrosion protection |
Automotive and transport structures require materials that combine lightweight performance, high strength, vibration resistance, impact stability, and fabrication efficiency. Hollow sections (SHS, RHS, CHS) offer all these properties, making them a backbone material for vehicle frames, transport equipment, and mobility systems.
🔹 Vehicle Chassis & Body Frames
Hollow sections are ideal for building rigid, lightweight, and impact-resistant vehicle frames.
Applications:
Preferred Sections: SHS / RHS (medium gauge). CHS for curved or roll-over protection structures (ROPS).
🔹 Bus Body & Coach Building
Hollow sections are widely used by bus body fabricators for:
Why HSS? Lightweight • High dimensional accuracy • Strong weld joints
🔹 Truck, Trailer & Cargo Transport Structures
HSS provide superior strength for load-bearing transport frames.
Applications:
Preferred Sections: RHS (for beams), SHS (for load posts)
🔹 Automotive Seating & Interior Components
Hollow sections ensure rigidity while keeping vehicles lightweight.
Applications:
Note: Thin-gauge RHS/SHS commonly used.
🔹 Material Handling Vehicles & Logistics Equipment
HSS are ideal for industrial mobility and transport systems:
🔹 Transport Infrastructure & Access Systems
Used in mobility engineering for:
| Section | Typical Size Range | Applications |
|---|---|---|
| SHS | 25×25 to 120×120 mm | Seat frames, cabin structures, chassis members |
| RHS | 40×20 to 200×100 mm | Bus & truck body frames, trailer beams |
| CHS | 19 to 76.1 mm OD | ROPS, curved sections, railing & supports |
Full automotive size chart available upon request.
