When architects, structural engineers, or fenestration fabricators open the official Jindal Aluminium Section Catalogue, they are presented with hundreds of pages featuring thousands of engineering profile drawings, dimensional callouts, and numeric die codes.
To newcomers, deciphering 4-digit and 5-digit section numbers, reading cross-sectional millimeter callouts, and differentiating between architectural and industrial geometries can seem daunting. Yet, the Jindal catalogue is organized with engineering precision.
Mastering how to navigate this document enables fabricators to accurately quote projects, eliminate on-site fitting errors, prevent costly ordering mistakes, and request exact dies from authorised stockists like Imperial Metal Mart in Delhi NCR.

The Anatomy of a Jindal Catalogue Entry
Every page in the Jindal Aluminium Catalogue displays multiple extruded profile blocks. Each block contains five standardized technical elements:
Section / Die Number (e.g., Sec. 1012, Sec. 3254)
This is the unique master tooling number assigned to that exact die by Jindal Aluminium. When ordering from stockists or distributors, quoting this number guarantees you receive the precise die silhouette, snap-fit grooves, screw bosses, and wall profile.
2D CAD Cross-Section Drawing
A true-to-scale transverse cross-section illustrating the geometry of the profile. It reveals whether the section is a solid bar, semi-hollow channel, or fully enclosed multi-chamber hollow box, along with internal screw ports, weatherstrip gasket tracks, and interlocking tongue-and-groove joints.
Dimension Callouts (Width × Height × Thickness in mm)
Detailed engineering callouts in millimeters (mm):
- A & B: External primary dimensions (e.g., Width × Height or Outer Diameter).
- T or t: Nominal wall thickness of the outer webs and internal ribs.
- R or r: Fillet or corner radii, showing whether edges are crisp 90-degree square corners or radiused stress-relief curves.
Perimeter / Girth Measurement
The total outer exposed surface perimeter measured in millimeters. This metric is used by powder coating applicators and anodizing plants to calculate surface area for chemical pre-treatment and electro-deposition coating pricing.
Category Classification Group
Indicates the functional engineering family: Architectural (windows, doors, curtain walls), Structural (angles, channels, beams), Industrial (tubes, rods, flats, busbars), or Transport (commercial vehicle bodies, flooring, cant rails).

How to Read Dimension Symbols in Section Drawings
When examining section drawings inside the catalogue, keep these universal conventions in mind:
- Outer Dimensions vs Inner Dimensions: Outer boundaries are always prioritized in catalogue callouts because they define frame fitment inside rough wall openings. Internal chamber dimensions define glass pocket depth and glazing gasket clearance.
- Web vs Flange Thickness: In open sections like U-channels and L-angles, the horizontal base is designated as the web, and the vertical legs are flanges. In heavy-duty architectural profiles, the web thickness may be thicker than the flanges to handle screw holding forces.
- Corner Fillets & Radii (R): Fillet radii rounded inside internal corners prevent stress concentration and profile cracking under mechanical bending or wind vibration.
- Dimensional Tolerances: All Jindal Aluminium extrusions conform to Indian Standards (IS:3965 / IS:2673) for dimensional, angularity, straightness, and twist tolerances, ensuring straight lengths for smooth mitering.
Specifying Surface Finishes in Jindal Orders
Extruded aluminium leaves the die in raw silver form. Depending on your project requirements, specify one of three standard surface treatments:
1. Mill Finish
Natural silvery finish straight off the extrusion press. Ideal for concealed internal frameworks, CNC machining, or workshops planning in-house powder coating.
2. Anodized Finish
Electro-chemically grown protective aluminium oxide layer (15 to 25 microns). Available in Natural Matt Silver, Champagne, Bronze, and Deep Black. Extremely scratch and corrosion resistant.
3. Powder Coated
Thermoset polyester architectural powder coating (60 to 80 microns). Available in any standard RAL shade (e.g., Pure White RAL 9016, Anthracite Grey RAL 7016, Charcoal, or Wood Grain).

Frequently Asked Questions
How do I match an existing aluminium section if I don't know the die number?
Cut a small 2-inch clean cross-sectional slice of your physical profile and bring it to Imperial Metal Mart in Paharganj, New Delhi, or send a calibrated digital photo with vernier calliper measurements of Width, Height, and Thickness. Our technical team can cross-reference it against our die index in minutes.
Does the section number change when ordering powder-coated or anodized finishes?
No. The Jindal section die number identifies the extruded geometric shape and tooling die. When ordering, the die number stays identical (e.g., Sec. 1012), and surface finish codes (such as MF for Mill Finish, NA for Natural Anodized, or PC with RAL number for Powder Coated) are added to the line item.
Where can I download the complete Jindal Aluminium Section Catalogue?
