In structural fabrication, commercial transportation, cleanroom partitions, and fluid conveying, Jindal Aluminium extruded tubes and pipesrepresent the industry standard in India. Extruded with micro-millimeter precision at Jindal's state-of-the-art Bangalore and Dhoot extrusion plants, these hollow sections combine high structural stiffness with an extraordinary strength-to-weight ratio.
However, mechanical engineers, industrial fabricators, and procurement officers frequently face estimating challenges: What is the exact theoretical weight per foot? What is the standard outer diameter tolerance conforming to IS 733 and IS 1285? Which alloy temper should be selected between 6063-T6 and 6082-T6?
As Delhi NCR's premier authorized stockist, Imperial Metal Mart maintains comprehensive ready inventories of round, square, and rectangular hollow sections. In this practical engineering guide, we provide complete dimensional references, theoretical weight formulas, and procurement checklists.
The 3 Core Tubing Geometries in the Jindal Extrusion Catalog
Jindal Aluminium manufactures hollow profiles across three geometric configurations, each tailored to specific mechanical load orientations:
1. Extruded Round Pipes & Tubes
Features completely uniform radial moment of inertia. Delivers optimal torsional rigidity and smooth aerodynamic or hydrodynamic fluid flow with minimal friction head loss.
Primary Uses:Architectural stair balustrades, industrial scaffolding uprights, pneumatic piping lines, heat exchanger sleeves, automotive drive shafts. Available from 9.5mm (3/8") OD up to 200mm+ OD.
2. Square Hollow Sections (SHS)
Engineered with equal moments of inertia along both principal axes (Ix = Iy). Outstanding resistance to column buckling under axial compressive loads.
Primary Uses:Cleanroom wall framework, pergola support posts, machine guards, modular conveyor framing. Standard sizes: 12.7x12.7mm (1/2") up to 100x100mm (4").
3. Rectangular Hollow Sections (RHS / Box Tubes)
Possesses an asymmetric cross-section with an enlarged primary vertical axis (Ix > Iy). Provides extreme resistance against downward deflection when spanning horizontal distances.
Primary Uses:Roof purlins, bus and truck body floor beams, architectural louvers, signboard frameworks. Standard sizes: 25.4x12.7mm (1"x0.5") up to 150x50mm (6"x2").
Theoretical Weight Calculation Formulas
When calculating bills of materials (BOM), engineers calculate theoretical weights using the standardized density of aluminium (ρ = 2.70 g/cm³ = 2,700 kg/m³):
Where OD = Outer Diameter in mm, t = Wall Thickness in mm.
Where W_outer = Width in mm, H_outer = Height in mm, t = Wall Thickness in mm.

Alloy Selection: When to Choose 6063-T6 vs. 6082-T6
Selecting the correct alloy ensures both structural safety and cost optimization:
- Specify Alloy 6063-T6 (Architectural Temper): Chosen for 90% of commercial framing, railings, display fixtures, and decorative applications. Features mirror-smooth extrusion surfaces that take crisp anodizing and powder coating without blemishes. Yield strength ≈ 214 MPa.
- Specify Alloy 6082-T6 (Structural Temper): High-strength structural alloy enriched with manganese and silicon. Mandatory for transport vehicles, military scaffolding, overhead truss systems, and marine structures subject to cyclic dynamic loading. Yield strength ≈ 260 to 280 MPa (almost 30% higher load capacity than 6063).
Frequently Asked Questions
What is the standard piece length of Jindal aluminium tubes?
Jindal Aluminium pipes and tubes are manufactured in standard lengths of 3.66 meters (12 feet) and 4.88 meters (16 feet). Custom extrusions up to 6.0 meters can also be ordered for large volume industrial applications through Imperial Metal Mart.
How can I confirm that my tubes are genuine Jindal Aluminium?
Authentic Jindal tubes carry continuous computerized inkjet printing along the length of each tube displaying the official "JINDAL" trademark, manufacturing plant code, extrusion die number, and alloy temper (e.g., 6063 T6). Furthermore, Imperial Metal Mart provides original factory Mill Test Certificates (MTC) verifying chemical and physical batch tests.
Can Jindal aluminium tubes be bent without crushing or kinking?
Yes. When bending thin-walled tubes for circular handrails or canopy arches, use rotary draw bending equipment with an internal steel mandrel or pack the pipe cavity with compacted dry silica sand. For extreme tight-radius bends, tubes in 6063-O (annealed temper) can be bent effortlessly and later heat-treated if required.
