In modern industrial automation, robotics, conveyor manufacturing, and CNC machine building across Delhi NCR, traditional welded mild steel frames have been almost entirely replaced by modular T-slot extruded aluminium profiles.
Welded steel frames demand tedious fabrication, welding jigs, stress-relieving, grinding, and repainting. If design specifications shift, modifying a welded structure requires destructive angle grinding.
In contrast, modular Jindal Aluminium T-slot profiles offer a 100% bolt-together solution. Using drop-in roll-in T-nuts, corner gusset brackets, and socket cap screws, automation engineers can build rigid, square machine frames in a fraction of the time—and reconfigure them effortlessly whenever production layouts evolve.
How T-Slot Profiles Work: Grooves & Fastening Mechanics
Every T-slot profile features continuous longitudinal grooves along its faces. These grooves are standardized into three primary slot width families:
6mm Slot (20 Series)
Designed for 20×20mm and 20×40mm profiles. Uses M4 and M5 T-nuts. Ideal for 3D printer chassis, electronic test benches, and lightweight camera sliders.
8mm Slot (30 & 40 Series)
Designed for 30×30mm, 40×40mm, and 40×80mm extrusions. Uses M6 and M8 T-nuts. The industry standard workhorse for factory workstations, conveyor frames, and machine safety guards.
10mm Slot (45 & 50 Series)
Designed for heavy-gauge 45×45mm, 45×90mm, and 90×90mm profiles. Uses M8 and M10 high-torque fasteners. Handles heavy robotic arm gantry loads and industrial CNC beds.

| 4040 Profile | 40.0 × 40.0 mm | 8.0 mm (Slot 8) | 6.8 mm (Tap M8) | Assembly workstations, machine perimeter guarding, safety fencing |
| 4080 Profile | 40.0 × 80.0 mm | 8.0 mm (Slot 8) | Two 6.8 mm bores | Conveyor side rails, linear actuator gantry beams, table legs |
| 4545 Heavy | 45.0 × 45.0 mm | 10.0 mm (Slot 10) | 10.0 mm (Tap M12) | Heavy-duty automation enclosures, robotic cell pillars |
| 8080 Heavy | 80.0 × 80.0 mm | 8.0 mm (Dual Slots) | Four 6.8 mm bores | Heavy CNC router chassis, automotive pallet transfer lines |
4 Key Fastening Accessories for Modular Framing
1. Drop-In Roll-In Spring T-Nuts
Feature an integrated spring ball that holds the nut in place vertically inside the slot. They can be inserted anywhere into an already-assembled frame without disassembling the ends.
2. Die-Cast Aluminium Corner Brackets
Heavy-duty 90-degree gussets featuring alignment tabs that slot directly into profile grooves, ensuring automatic squareness without squaring tools.
3. Hidden Internal Joint Connectors
Blind connectors and central screw fasteners that sit completely concealed inside the profile slot, leaving exterior faces flush for mounting clear acrylic or polycarbonate safety panels.
4. Black PVC Slot Cover Strips & End Caps
Snap-in flexible PVC cover strips seal unused T-slots, preventing dirt and metal swarf accumulation in cleanroom and food-processing environments while routing sensor wires cleanly.
Frequently Asked Questions
What is the difference between T-Slot and V-Slot profiles?
Standard T-slot profiles feature flat 90-degree internal groove lips designed for maximum clamping torque with T-nuts and corner brackets. V-slot profiles have 45-degree chamfered outer lips that allow dual V-wheels to ride directly inside the groove as a linear motion slide guide.
What standard lengths are T-slot extrusions supplied in?
Jindal modular T-slot profiles are supplied in standard mill lengths of 3.0 meters, 3.66 meters (12 feet), and 6.0 meters. Imperial Metal Mart can precision saw-cut profiles to your exact CAD bill-of-materials with tapped end bores.
