CNC V-grooving channel milled into stainless steel sheet before bending

The difference is in the edge

Laser → V-groove → bend → weld → finish → inspect. One chain, one workshop, your drawing.

V-grooving vs normal bending

Design samples · panels

Panel samples,
ready to build

Cassettes, perforated tiles and fluted panels folded on four sides. Each one shows the flat pattern with its bend lines, the panel in 3D, the edge details and how it goes up.

Why every sample is V-grooved

An ordinary press brake wraps the sheet round its tool, so the outside corner comes out round. We first cut a V along each bend line, leaving a thin web of metal, then fold: the sheet closes into the V and the corner comes out sharp. Each sample below shows where its V-cuts go.

Every sample has a sample ID to quote, a free PDF datasheet (no registration) and its CAD file on WhatsApp.

Hidden-fix façade cassette

A tray panel with a return and a lip on all four sides: a flat face with no screw in sight.

What makes it different. The four lips meet in mitred corners (cut on the diagonal), so the corners are closed and neat from behind too.

Where it is used

  • Façade and soffit cladding
  • Column and beam wraps
  • Feature walls in lobbies

How it goes up

  1. Fix a sub-frame of rails to the wall.
  2. Fix each cassette to the rails through its returns or lips, so the face stays clean.
  3. Leave the same open joint all round; it becomes the pattern of the façade.

Gradient-perforated cassette

Round holes that grow from small at the bottom to large at the top: the panel fades from solid to open.

What makes it different. Each hole is laser cut at its own size, so the gradient is smooth; a plain border keeps the cassette stiff.

Where it is used

  • Screens in front of services or windows
  • Façade bands and parking fronts
  • Lit feature walls

How it goes up

  1. Fix like the façade cassette: a rail sub-frame, fixings through the returns.
  2. Fit lighting or a backing behind if the gradient is to glow or be read against a colour.
  3. Hang panels in the order shown on the layout drawing so the gradient runs on.

Lift-wall panel with shadow joint

A shallow tray panel in champagne PVD: set side by side, the returns leave a fine shadow joint.

What makes it different. Shallow returns keep the panel light; the V-grooved edges stay sharp in a reflective PVD finish.

Where it is used

  • Lift car and lift lobby walls
  • Reception and counter fronts
  • Feature walls in hotels

How it goes up

  1. Bond the panels to the wall or lift-car board with structural adhesive tape.
  2. Use spacers in the joints while the adhesive sets, then remove them.
  3. Start from the centre line so the joints are even on both sides.

What makes it different. Hexagon holes give a higher open area than round holes at the same bar width, with an unusual look.

Where it is used

  • Ceilings in offices, retail and transit spaces
  • Service ceilings that must stay open to the air
  • Feature ceiling zones

How it goes up

  1. Lay the tiles into a standard 600 × 600 exposed T-grid.
  2. An acoustic fleece or a backing can be laid on top where the design needs it.
  3. Tiles lift out for access to the services above.

What makes it different. Every flute is a V-grooved fold, so the ridges are sharp and the light catches each one.

Where it is used

  • Feature walls and reception backdrops
  • Column cladding
  • Bar fronts and counters

How it goes up

  1. Bond the panels to a plywood or board backing, or screw through the side returns into a frame.
  2. Butt the panels side by side; the returns line up the flutes.
  3. Finish the ends with a matching trim profile.

What makes it different. Deep square flutes with sharp outside corners are hard to fold on a normal press brake; V-grooving makes them crisp.

Where it is used

  • Statement walls in hotels and showrooms
  • Lift lobbies
  • Façade bands at ground level

How it goes up

  1. Screw through the side returns into a timber or steel frame.
  2. Join the next panel so the land widths match and the rhythm runs on.
  3. Close the top and bottom with a flat trim or leave a shadow gap.
