Double Head Cutting
Every profile starts here. Twin saw heads cut both ends at once, to a tenth of a millimetre.
- ±0.1 mm, servo-driven
- Any angle, 45° to 90°
- Cut-lists straight from design software
Manufacturing
Precision set at the profile level.
Our line covers the two construction methods that between them account for almost all aluminium fenestration and curtain wall: mitred corners mechanically crimped, and butt-jointed mullion-to-transom assemblies cut with a notch-and-tenon end mill.
Fenza fabricates from a facility in Gurugram, Haryana, India. We work on one thing — the outside of the building — engineered, made on our own line, and installed by our own teams.
The line runs CNC-grade aluminium machinery for cutting, routing, crimping and end-milling, which lets us hold tolerance at the profile level — the discipline that decides whether a facade stays watertight, square and true once it is up.

From bar to frame, on one line.
Copy Router
Holes, slots and drainage paths, machined into the profile before anything is assembled.
- Drilling, milling and drainage in one set-up
- Pneumatic clamping for repeat accuracy
- High-speed spindle
Corner Crimping
Mitred corners pressed together from both sides at once, so the frame closes square.
- Equal pressure on both sides
- Heads adjustable in three axes
- No profile slip
End Milling
Transom ends shaped to fit the mullion exactly: the joint that keeps a curtain wall tight.
- Notch-and-tenon ends
- Tooling for multiple profile sections
- Quick changeover between sections

Method
Two ways to build a corner.
Our line covers the two construction methods that between them account for almost all aluminium fenestration and curtain wall.
Mitred and crimped
Profiles cut to a 45° mitre, hardware prepped on the copy router, and corners mechanically crimped for a tight, square joint that does not rely on welding.
Mitred, mechanically crimped corner
Butt-jointed, notch-and-tenon
Mullion-to-transom assemblies cut with a notch-and-tenon end mill, so transoms seat square against mullions and the joint stays watertight.

Production house
Where tolerance is set.
Precision at the profile level is what makes a facade watertight, square and durable on site. This is the order the work runs in.
01
Profile cutting
Aluminium is sliced with a non-ferrous circular blade, or a carbide-tipped fine blade, so the cut face stays clean and the section is not dragged out of square.
02
Drilling
The bit is rotated at a set speed and fed at a set rate to open cylindrical holes, with the profile held down in vices and clamps throughout so nothing creeps mid-cut.
03
Assembly & racking
Mullions are cut to length on the double head machine, holding angle and tolerance across the batch; transoms are cut, labelled and stacked to the erection sequence.
04
Visual inspection
The production in-charge inspects against the approved drawing before despatch — the point is to find the problem here rather than on the elevation, where it becomes a programme delay.
Plant capacity and facility area for the Gurugram unit are being confirmed and are deliberately not stated here.
Surface & Finish
Colour consistency, surface durability.
All aluminium is finished to the project specification, applied to extruded 6063-T6 sections before fabrication.
Mill Finish
Untreated extruded aluminium. For concealed sub-structure and carrier framing.
Anodised
Natural silver, champagne, bronze and black. Typical coating class 15–25 microns.
Powder Coated
Full RAL range, matt / satin / textured. Typical film thickness 60–80 microns.
PVDF
Polyvinylidene fluoride for high-UV external exposure. Metallic and solid shades.
Finish ranges, coating thickness and any colour warranty are confirmed with the approved applicator for each project. Wood-grain and stone-effect sublimation finishes are available on request.
