Delta Wing Stone Panel
Flutes with a cut across them. Every rib is split by a shallow diagonal, so the wall reads as grey fluting from the door and as a field of small chevrons once you are close.

The pattern is a broad vertical flute, about 22 mm on centres, with a single angled cut taken across each rib at a repeating height. In the grey it looks like a machined panel; in the cream it looks like cast plaster. The cut is shallow, maybe 1.5 mm, but it is enough to break the vertical line at close range.
Six millimetres, 7 kg, and a 1200 × 3000 sheet. The relief is regular enough to run across a long wall without the pattern drifting, which is more than can be said for most hand-carved fluting, and the joints can be set on the flute lines so a 6 m wall shows two. It goes out as faux stone panels for shopfronts and hotel corridors, the places where real stone gets quarried and then value-engineered out.
One cut, repeating
The diagonal is the whole idea, and it is easy to get wrong: cut it too deep and the flute reads as broken, too shallow and it disappears under raking light. In the texture shot the break is just visible at a metre and obvious at 300 mm.
Grey for the bar
The bar is the grey, run vertically behind a back bar with the shelves cutting across it, so the chevrons line up with the bottle rows by accident rather than design. The boardroom is the same sheet in cream, quieter, and it is the version that gets specified twice.
Installed, delta wing stone
Good for
- Bar fronts and back bars
- Boardrooms and reception walls that need texture without a pattern
- Long corridors, where the chevron cut stops the flute reading as a stripe
- Columns, if the flute lines are set out to the joint
Not for
- Small rooms; the chevron needs two metres to resolve
- Bathrooms with a hand shower aimed at the wall
- Anywhere the wall will be seen only in silhouette
Four greys and a cream
The card is mostly grey: a warm grey, a cool grey, a graphite and a near-black, plus the cream in the main shot. On a wall with no direct light the graphite reads almost flat; under a downlight it is the most dramatic thing in the range.

Questions we get asked
What does “delta wing” refer to?
The shape of the cut across each rib. It looks like the underside of a delta wing, and the name stuck in the factory before anyone thought of a better one.
Can the sheets be joined invisibly?
No, and they should not be. Set the joint on a flute line and keep a 2 mm shadow; a butt joint in a fluted face always telegraphs.
Is the grey a painted finish?
It is cast through the sheet, not painted on top, so a scratch shows the same grey.
How deep is the relief?
About 4 mm from the top of a rib to the valley, plus the 1.5 mm chevron cut.
