Aluminium Extrusions for Commercial Vehicles Truck Bodies and Bus Body Profiles

In India's rapidly growing commercial logistics, cold-chain transport, and electric mobility (EV) sectors, vehicle body builders are undergoing an irreversible shift away from heavy mild steel to precision extruded aluminium commercial vehicle profiles.

Traditionally, bus bodies and truck cargo boxes fabricated from carbon steel suffered from rapid rust corrosion under monsoon rains, heavy deadweight that wasted diesel fuel, and restricted legal payload capacity.

By switching to high-strength Jindal Aluminium transport sections, fleet builders slash vehicle body tare weight by 35% to 45%. This dramatic weight reduction allows logistics operators to carry significantly more commercial freight per trip, cuts tyre wear, improves diesel mileage, and extends the driving range of electric buses per battery charge.

The 5 Essential Extrusion Profiles in Commercial Vehicle Building

Building an aerodynamic, high-strength commercial vehicle body requires specialized interlocking extruded shapes from the Jindal Aluminium Catalogue:

Heavy Duty Flooring

1. Interlocking T-Fluted Flooring Planks

Extruded hollow floor planks featuring tongue-and-groove side locks and raised non-slip top ridges.

Primary Uses: Cargo truck floors and refrigerated (reefer) container decks. The raised T-slots allow cold air to circulate beneath stacked vegetable, dairy, or pharmaceutical pallets while enabling easy water wash-downs.

Wall Framework

2. Vertical Side Pillars & Cant Rails

Heavy-duty structural vertical uprights and horizontal upper cant rails forming the skeletal perimeter cage of bus and truck bodies.

Primary Uses: Commercial bus side walls, delivery van side frames, and modular shipping containers.

Roof Engineering

3. Curved Roof Bows & Ceiling Trusses

Curved structural rafters that span across the ceiling width, supporting exterior aluminium roof sheets and interior passenger ceiling panels.

Primary Uses: City transit buses, luxury tourist coaches, and airport tarmac shuttle buses.

Impact Protection

4. Exterior Rub-Rails & Side Under-Run Bars (SUPD)

Heavy extruded protective bumpers mounted along the lower exterior perimeter of trucks and trailers.

Primary Uses: Protects vehicle bodywork from loading dock scrapes and satisfies mandatory road safety regulations (Side Under-Run Protection Devices).

Safety Steps & Ramps

5. Aluminium Chequered Plate Profiles

Extruded and rolled plates featuring embossed 5-bar slip-resistant tread patterns.

Primary Uses: Bus entry footsteps, tail-lift loading ramps, ambulance interior walkways, and fire engine decks.

Why Aluminium Trumps Steel for Commercial Vehicles

  • Increased Revenue per Trip: Because an aluminium truck container weighs hundreds of kilograms less than a mild steel body, transport companies can legally carry additional cargo payload on every single highway run without exceeding RTO gross vehicle weight (GVW) limits.
  • 100% Rust Immunity: Cold-chain reefer trucks carry ice and frozen foods that cause steel floorboards to rust out in 3 to 4 years. Aluminium never rusts, lasting over 15+ years in wet refrigerated conditions.
  • High Scrap Salvage Value:At the end of a commercial vehicle's 15-year lifecycle, mild steel bodies have virtually zero salvage value due to rust flakes. In contrast, an aluminium vehicle body retains over 75% to 85% of its raw metal market value when recycled.

Frequently Asked Questions

What standard lengths are vehicle body extrusions supplied in?

Jindal transport sections are manufactured in standard lengths of 3.66 meters (12 feet), 4.88 meters (16 feet), and 6.0 meters (20 feet) to match standard truck chassis wheelbases across India.

How are aluminium bus body sections joined together?

Commercial vehicle body builders assemble aluminium sections using high-shear structural blind rivets (Huck bolts or Avdel fasteners) and TIG/MIG welding. Structural polyurethane (PU) adhesives are also used to bond exterior aluminium skin sheets to the internal frame, eliminating visible exterior rivet heads.

Can Imperial Metal Mart supply transport profiles in Delhi NCR?

Yes. Imperial Metal Mart stocks genuine Jindal Aluminium tubes, corner angles, floor planks, and structural transport profiles in Paharganj, New Delhi, serving vehicle body builders and fabrication workshops across North India.
