Jindal Aluminium Section Weight Chart: Complete Dimensions & Weight Per Meter Guide

In architectural engineering, structural glazing, facade fabrication, and industrial manufacturing, precise material estimation is the foundational pillar of budget control, structural safety, and project success. Aluminium is traded, billed, and structurally engineered on the basis of unit weight (kilograms per meter or metric tonnes) rather than linear length alone. Sourcing authentic extruded profiles from Jindal Aluminium Limited (JAL)—India's premier and largest aluminium extruder—requires structural consultants, facade fabricators, procurement managers, and civil contractors to have immediate access to standardized, mathematically verified weight metrics.

This authoritative engineering manual and technical guide, curated by the metallurgical engineering team at Premier Aluminium Traders (Paharganj, New Delhi), delivers the universal mathematical formulas, verified section weight charts, alloy temper comparisons, Indian Standard (IS) tolerances, and commercial costing frameworks required to accurately engineer, specify, and procure Jindal Aluminium sections across India.

1. Key Takeaways & Executive Summary

Section weight calculation is the critical variable that directly governs raw material procurement costs, dead-load calculations for high-rise building facades, container payload logistics, and structural compliance. Standard commercial aluminium alloys (predominantly 6063, 6061, 6082, and 6101) exhibit a nominal metallurgical density of 2.70 g/cm³ (2700 kg/m³ or 0.0000027 kg/mm³). Standard commercial stock lengths supplied by Jindal Aluminium Limited range from 12 feet (3.657 meters) to 16 feet (4.876 meters), with custom architectural lengths up to 24 feet (7.315 meters) available for continuous curtain wall mullions.

2. The Universal Aluminium Weight Calculation Formula

Aluminium profile weights are fundamentally derived from the cross-sectional area of the profile multiplied by the alloy's volumetric density and the total length of the section. Understanding these formulas allows engineering teams to calculate theoretical section weights directly from CAD fabrication blueprints before physical dies are extruded.

The Fundamental Mathematical Relationship

Weight (kg) = Cross-Sectional Area (mm²) × Length (m) × Density (kg/mm³)

For standard commercial aluminium alloys with a density of 2.70 g/cm³:

Weight per Meter (kg/m) = Cross-Sectional Area (mm²) × 0.0027

Formula Breakdown by Cross-Sectional Profile Geometry

a) Solid Square & Rectangular Flat Bars

For solid architectural flat bars and electrical busbars:

Weight per Meter (kg/m) = Width (W in mm) × Thickness (T in mm) × 0.0027
Total Section Weight (kg) = Width (mm) × Thickness (mm) × Length (m) × 0.0027

Example Calculation: Calculate the weight of a Jindal 50 mm × 6 mm solid flat bar of 12-foot length (3.657 meters):

• Cross-Sectional Area = 50 × 6 = 300 mm²
• Weight per Meter = 300 × 0.0027 = 0.810 kg/m
• 12 ft Weight = 0.810 × 3.657 = 2.962 kg per bar

b) Solid Round Rods

For solid machining rods and structural pins:

Weight per Meter (kg/m) = π × (Radius in mm)² × 0.0027
Simplified Formula: Diameter (D in mm)² × 0.0021206
Total Rod Weight (kg) = D² (mm) × 0.0021206 × Length (m)

Example Calculation: Calculate the weight of a 25 mm diameter Jindal solid round rod of 12-foot length:

• Weight per Meter = 25² × 0.0021206 = 625 × 0.0021206 = 1.325 kg/m
• 12 ft Weight = 1.325 × 3.657 = 4.845 kg per rod

c) Hollow Square Tubes / Box Sections

For equal hollow box profiles used in interior partitions and framework:

Weight per Meter (kg/m) = [Outer Width² - Inner Width²] × 0.0027
Alternative Formula: 4 × Wall Thickness (T) × [Outer Width (W) - Wall Thickness (T)] × 0.0027

Example Calculation: Calculate the weight of a 50 mm × 50 mm square tube with a 2.0 mm wall thickness:

• Outer Width = 50 mm, Inner Width = 50 - (2 × 2) = 46 mm
• Area = (50² - 46²) = (2500 - 2116) = 384 mm²
• Weight per Meter = 384 × 0.0027 = 1.037 kg/m
• 12 ft Weight = 1.037 × 3.657 = 3.792 kg per pipe

d) Hollow Rectangular Tubes

For unequal rectangular hollow sections utilized in framing and structural transoms:

Weight per Meter (kg/m) = [(Outer W × Outer H) - (Inner W × Inner H)] × 0.0027
Alternative Formula: 2 × Wall Thickness (T) × [(Outer W + Outer H) - (2 × T)] × 0.0027

Example Calculation: Calculate the weight of a 100 mm × 50 mm hollow section with a 2.5 mm wall thickness:

• Outer Area = 100 × 50 = 5000 mm²
• Inner Width = 100 - 5 = 95 mm, Inner Height = 50 - 5 = 45 mm
• Inner Area = 95 × 45 = 4275 mm²
• Net Metal Area = 5000 - 4275 = 725 mm²
• Weight per Meter = 725 × 0.0027 = 1.9575 kg/m
• 12 ft Weight = 1.9575 × 3.657 = 7.158 kg per section

e) Hollow Round Pipes / Tubes

For circular architectural railings, conduits, and fluid transport lines:

Weight per Meter (kg/m) = (Outer Diameter - Wall Thickness) × Wall Thickness × 0.0215
Alternative Formula: π × (Outer Radius² - Inner Radius²) × 0.0027

Example Calculation: Calculate the weight of a 50.8 mm (2.0 inch) OD Jindal pipe with a 1.5 mm wall thickness:

• Weight per Meter = (50.8 - 1.5) × 1.5 × 0.0215 = 49.3 × 1.5 × 0.0215 = 1.590 kg/m
• 12 ft Weight = 1.590 × 3.657 = 5.815 kg per pipe

f) Equal & Unequal Angles (L-Sections) and Channels (U-Sections)

For structural L-angles and perimeter glazing channels:

Angle Weight (kg/m) = [Leg 1 (mm) + Leg 2 (mm) - Thickness (mm)] × Thickness (mm) × 0.0027
Channel Weight (kg/m) = [Base (mm) + 2 × Flange Height (mm) - 2 × Thickness (mm)] × Thickness (mm) × 0.0027

6. Practical Tips to Calculate Material Costs from Weight

In the commercial B2B metal trade across India, aluminium extrusions are priced based on the following comprehensive cost formula. Knowing your exact theoretical or actual weight allows you to calculate final project billing with precision.

Total B2B Billing = [Total Weight (kg) × (Base Metal Rate/kg + Extrusion Premium/kg + Surface Treatment/kg)] + GST (18%)

Breakdown of Cost Components:

1. Base Metal Rate (NALCO / MCX Linked):
   • The primary raw material cost fluctuates with global LME and domestic NALCO primary aluminium ingot pricing benchmarks.
2. Extrusion Conversion Premium:
   • The manufacturing cost charged by the extrusion press based on section complexity, wall thickness, and die difficulty. Solid sections have lower extrusion conversion premiums than complex multi-cavity hollow curtain wall profiles.
3. Surface Treatment Add-ons:
   • Mill Finish: Raw extruded surface (No added finishing cost).
   • Anodizing: Chemical electrolytic treatment (Natural Silver, Champagne, Bronze, Black). Priced per kg or per sq. meter based on micron rating (typically 15 to 25 microns for architectural outdoor exposure).
   • Powder Coating: Electrostatic thermoset polymer application (RAL shades). Adds approximately ₹25 to ₹45 per kg depending on coating warranty (10-year, 15-year, or 25-year PVDF).
4. Statutory Goods & Services Tax (GST):
   • Aluminium profiles and extrusions fall under HSN Code 7604 with a statutory GST rate of 18%.
