How do I use Coffee Wood Marble for a staircase?

On full-thickness treads with a nosing that is cut as one piece, not applied. A stair is the hardest-wearing horizontal surface in a building and the part that is most often cut from a thin piece with a nosing added to it.
A finished interior with dark wood-grain stone cladding on the walls, a matching stone floor, dark doors and a black sculpture on a plinth
Wall cladding in a room, the panels running the full height of the wall.
Hands holding a rectangular cut stone sample with a finished edge against the face of a large polished marble slab
The edge of a cut-to-size piece, which is what a wall panel is before it is fixed.

Reference photographs. They show the material and the finish; they are not photographs of goods we made, and the colour on screen is not a colour-match.

The figures, and where each one comes from

The element What it needs
The tread Cut in one piece, with the nosing part of the same slab
The thickness 30 mm where the edge is seen, and 20 mm where it is not
The figure The lines running with the travel of the stair
The substrate Level, and it carries the load

Why it behaves the way it does

The nosing is the part that wears first and the part that shows a joint if it is made in two pieces. On a straight figure the nosing joint is a horizontal line across a surface whose lines all run the other way, and it is the first thing anyone looks at.

What these figures are, and what they are not

We supply the treads and the risers cut to size. The structure, the support and the installation are the fabricator's and the builder's.

If you are specifying this

We have not published products against this question yet. Send us the process, thickness and quantity and we will quote it against what we can actually form, rather than against a catalogue.
