CNC jaali cutting in Delhi

Anyone can cut a nice pattern. What separates a jaali screen that survives ten years from one that sags in six months is how much board is left behind after the pattern is removed, and where that remaining material runs.

CNC jaali cutting in Delhi mostly gets specified for three jobs: a partition that separates without closing, a screen over a window or a duct that lets air and light through, and a decorative face over a solid wall. The first two carry themselves; the third does not have to. We ask which one it is before quoting, because the answer changes the minimum web width, the board and sometimes the pattern itself.

The rule we work to is that no unsupported web should be thinner than about 8mm in 12mm MDF, and continuous material has to run corner to corner in at least one direction — a pattern made only of isolated islands linked by thin bridges will rack. Where a client's chosen motif does not meet that, we thicken the webs by a millimetre or two rather than change the design; at normal viewing distance nobody sees the difference, and the screen stops flexing when a door slams.

Sized to the opening, not to the sheet

Screens get cut to the measured opening. That sounds obvious and it is where most jaali jobs go wrong: a pattern designed for a 1200mm width and then squeezed into 1140mm on site has a visibly compressed column at one end. We draft the motif to your dimension so it lands on a full repeat, or so the part-repeat falls behind the frame where nobody reads it. Openings taller than 3050mm are split, with the break placed along a structural line of the pattern and a horizontal rail hiding the joint.

The frame comes off the same file — MDF or ply frames for internal partitions, and a routed rebate that lets the screen sit flush rather than proud. Hinges, floor channels, cut-outs for a handle or a track: all machined, none drilled on site into a thin web.

Room dividers and free-standing partitions

A full-height divider that is not fixed to a wall at one edge needs more than a jaali panel. Practically, that means either a substantial frame around all four sides, a floor channel, or a heavier board — usually 18mm HDHMR rather than 12mm MDF, because HDHMR holds a screw right at the edge and stays flat over a 2.4m span where MDF would bow. Where the divider has to be movable, we build it as framed leaves rather than one panel.

Outdoors, on a balcony or in a wet area, the answer is waterproof WPC. It will not chip, it does not care about rain, and it holds a jaali pattern well as long as the webs are kept slightly wider than they would be in MDF.

Signage runs on the same beds and comes up in the same conversations, so it belongs here rather than on a page of its own.

Cut lettering, logo panels and backlit signage in board — routed out of MDF or HDHMR for anything over 10mm or anything structural, and laser cut where the letterform has fine serifs, tight counters or small internal detail that a 3mm router bit cannot reach. Letters can be surface-mounted on stand-offs, recessed into a carved field, or backed with acrylic and lit from behind by your electrician; we cut the board and the mounting holes, we do not do the wiring.

Send the logo as vector artwork — AI, PDF, DXF or CDR with the type converted to outlines. A raster logo can be traced but the curve quality depends entirely on the resolution you send, and we will tell you before cutting if it will not hold up at size.

• Wordmarks and logos cut in 6mm–25mm board, painted, laminated or PU finished
• Signage raised out of a ribbed or parametric field, cut as one piece
• Backlit letter boxes and channel returns, cut and assembled ready for your LED
• Reception and directory panels, engraved rather than cut through
