• High strength
• Sturdy construction
• Durability

• Lightweight yet Strong: Aluminium tubing is about one-third the weight of steel tubing of the same size, making it easier to transport and install, but still offers impressive durability.
• Corrosion Resistance: Aluminium naturally forms a protective oxide layer when exposed to air, which makes it highly resistant to corrosion in various environments, including marine and outdoor applications.
• Thermal and Electrical Conductivity: It has excellent thermal and electrical conductivity, making it suitable for heat exchange systems and electrical components.
• Workability: Aluminium is easy to cut, drill, bend, and weld using common tools and techniques, which is why it's a favorite for DIY projects and fabrication.
• Recyclability: Aluminium is 100% recyclable without losing its natural properties, making it an environmentally friendly choice. 

• High Precision: The drawing process allows for very tight tolerances, ensuring highly accurate outside diameters, inside diameters, and wall thicknesses.
• Superior Surface Finish: It offers a smoother surface finish compared to extruded tubes, often requiring less secondary machining or treatment for aesthetic or functional requirements.
• Enhanced Strength: The cold working process increases the material's tensile strength and hardness (work hardening), making it more durable and resistant to fatigue.
• Uniformity: Drawn tubes exhibit superior wall consistency (concentricity) along their length, which is crucial for high-pressure applications like hydraulic systems. 

• Aerospace: High-precision fuel lines, hydraulic systems, and structural components.
• Medical Equipment: Surgical instruments and hospital devices.
• Industrial Machinery: Precision tools, instrumentation, and robotics.
• Heat Exchangers/HVAC: Condensers, evaporators, and refrigeration systems.

• Durability & Weather Resistance: Aluminium will not rust, withstands moisture & weather better than many metals.

• Low Maintenance: Sliding mechanism simple; regular cleaning and occasional lubrication is usually enough.

• Aesthetic & Slim Profiles: Aluminium sections allow slim frames, more glass-to-frame ratio, better views/light.

• Flexibility: Many designs, finishes, glass options, tracks etc.

• Space-Efficient: Sliding doesn’t need swing room, good for tight spaces.

• Thermal Conductivity: Aluminium is a good conductor — without thermal break or good glazing, it can make interiors hotter or colder.

• Noise / Sealing: Poorly fitted or lower quality hardware may allow air leakage, noise, or water seepage. The quality of seals / weather-beading matters.

• Operation Smoothness: Rollers & tracks must be good quality; cheap ones wear quickly or jam.

• Cost Variation: Premium finishes / thicker glass / more elaborate frames can go up in cost quickly.

• Installation Quality: Even the best window performs poorly if badly installed (alignment, sealing, drainage etc).

If you’re considering one, here are checklist items:

1. Profile Section Details: what “Jindal series” is it? Dimensions, wall thickness, visible face.

2. Glass Spec: thickness, clear/tinted/toughened/double glazed etc.

3. Finish & Coating: powder coat / anodized / wood-look etc; check durability of coating.

4. Track / Roller System: type and load capacity of rollers; number of tracks; ease of replacement.

5. Locking & Seal: how many locks; whether weather sealing/gasket is provided/quality.

6. Drainage / Weep holes: check design for rainwater drainage.

7. Warranty / After Sales: for the frame finish, hardware, and glass.

8. Price Breakdown: quoted per sq ft or per unit; ask whether installation, transport etc included.

• Lightweight & Strong: Aluminium is about one-third the weight of steel, yet certain alloys and extrusion designs (e.g., with internal reinforcements) provide comparable or superior strength for specific applications.
• Corrosion Resistance: Aluminium naturally forms a protective oxide layer that makes it highly resistant to rust and degradation, a quality that can be further enhanced by finishes like anodizing or powder coating.
• Design Flexibility: The process allows for the creation of intricate and complex shapes, including hollow, semi-hollow, and various multi-chambered profiles (e.g., T-slots), which simplify assembly and reduce the need for mechanical joints.
• Thermal & Electrical Conductivity: Extruded aluminium is an excellent conductor of heat and electricity, making it suitable for applications such as heat sinks and electrical grounding systems.
• Cost-Effectiveness: The extrusion process is relatively inexpensive for tooling and production compared to other metal forming methods, with minimal material waste due to high recyclability. 

• 6061 Aluminum: Known as "structural aluminum," this alloy provides a great balance of strength (especially after T6 heat treatment), machinability, and weldability. It is widely used in aerospace components, heavy-duty machinery, and high-performance sporting equipment. An example product is the NUFIT Aluminium 6061 T6 Round Pipe.
• 6063 Aluminum: Often called "architectural aluminum," this grade is optimized for extrudability and a superior surface finish, making it ideal for visible architectural elements, window/door frames, and decorative trim. An example product is JINDAL make MILL FINISH Aluminium Round Pipe, Grade Aa 6063 T6.

Also, some channel section examples:

• Jindal aluminium channels 55 × 3500 × 2.1 mm, approx 2.8 kg/m L&T-SuFin

• Jindal channel 62 × 31.8 mm, also ~ 2.5 kg/m L&T-SuFin

• Many sections are alloy 6063 (or equivalent) — common in window/door extrusions for its good strength + good extrudability.

• Some are marked “E350” etc in listings. L&T-SuFin+1

• Standards: IS (Bureau of Indian Standards) for extruded aluminium shapes, e.g. “IS 733” for channels etc. L&T-SuFin

From the Jindal catalogue:

• Section number (each unique design has its number)

• Shape type (bar / tube / channel / angle / handle / sliding track / window frame etc.)

• Dimensions of critical faces, wall thicknesses or multiple faces for complex profiles.

• Weight per meter (important for load bearing, cost estimation). Scribd

• Finishing / grooves etc (can include grooves for glass beads, gaskets, sealing etc.) — the more complex, the more machining, cost etc.

If you’re specifying or buying, these are useful details to request:

1. Section number — that identifies exact profile.

2. Overall dimension (height, width of visible face, depth etc.).

3. Wall thickness (solid/hollow parts).

Here are some typical section types used, with use case:

• Outer frame section — large profile, solid or hollow back, supports weight, interface with wall.

• Shutter vertical & horizontal members — smaller sections that form door/window sash or sliding shutter.

• Sliding tracks — special “track” sections, usually with grooves / rails, hollow gutters, etc.

• Weather beads / interlocks — small profiles used to interlock shutter & frame to avoid water ingress.

• Casement / Hinged sections — profiles that allow hinges and sealing on openable windows.

• Heat Exchangers/HVAC: Condensers, evaporators, and refrigeration systems.

• Construction: Framework for doors, windows, and curtain walls; handrails, fencing, and staircases.
• Manufacturing: Construction of machinery, equipment, and modular assembly systems (e.g., T-slot profiles).
• Automotive/Aerospace: Vehicle frames, trailer components, suspension systems, and aircraft structures where a high strength-to-weight ratio is crucial.
• General Fabrication & DIY: Workstations, shelving, display fixtures, and various home improvement projects.
