Round Line Stone Panel
Convex ribs, not concave. The light sits on top of each one and the shadow falls in the gap between, which is the opposite of a groove and reads warmer at eye level.

Each rib is a half-round about 20 mm wide, standing proud of the sheet with a gap of 6. This is the profile a plasterer would have run with a mould in a 1930s flat, and it has the same effect now: it makes a flat wall feel like it has thickness.
Eight millimetres, 9 kg, in 600 and 1200 widths. The round rib is the most forgiving of the linear group on a curved wall, because a convex form compresses into a radius without the valleys closing up. That is why it turns up on columns and on the inside of a curved reception desk. This is the flexible stone panel that gets specified for columns, because the ribs are convex and a column has no corner to hide a joint in.
Light on top, not inside
The texture shot is taken with the light coming from the left at about 30 degrees, which is how a wall is usually lit. Every rib has a bright top, a mid-tone shoulder and a dark gap, and that three-tone reading is what a groove cannot do: a groove is dark, and stays dark.
Boutique, then lobby
The boutique is the 600 width in a pale clay, run full height with the shelves cutting across the ribs. The lobby is the 1200 in the same colour, and the change in width changes the scale of the room more than the colour does.
Installed, round line stone
Good for
- Boutique retail and small hotels
- Curved reception desks and columns
- Period refurbishment, where a run plaster profile is being copied
- Wall panels behind a bed or a banquette
Not for
- Exterior walls; the convex rib holds rain
- Kitchens, for the same reason
- Anywhere a hard directional light will graze the wall from below
Convex ribs into a curve
The bend shot is a 600 sheet at a 250 mm radius, which is tighter than any of the grooved profiles will go. The ribs compress on the inside of the curve and the gaps close slightly, which on a convex profile looks deliberate.
Bent by hand, no heat
Clay, chalk, grey
Three colours: a pale clay that is almost pink in warm light, a chalk white, and a mid grey. The clay is the one that sells, because a round rib in a warm colour looks like plaster and a round rib in white looks like plastic.

Fitting it
Four steps, and the third one is the one that goes wrong.
Questions we get asked
Round or square rib — how do I choose?
Round if the room is warm, period or residential. Square if it is commercial and lit from the side. Round hides a bad substrate better; square shows it.
What is the gap between ribs?
Six millimetres, which is wide enough to dust with a brush and narrow enough not to read as a channel.
Can it wrap a column?
A 600 mm column takes four sheets with the joints in the gaps. Down to about 250 mm radius.
Does the colour change with the light?
The clay does, noticeably. Under a warm downlight it goes pink; under daylight it is closer to oat. Order a sample and look at it in the room.
