Product description
Curved stairs need every piece cut to its own geometry. The photo shows finished curved blocks on a pallet, each marked with its position so the installer can set them in order without measuring on site.
We work from your plan and section drawings — radius, rise, going and nosing — and can return shop drawings for approval before cutting. Tops are usually flamed; fronts flamed or sawn.
