The porphyry steps are cladding elements of stairs used mostly for external environments: formed by a tread (horizontal walkway element) and by a riser (vertical element that determines the height of the step).
The porphyry steps in addition to the beauty given by the colors of natural stone are above all a functional and lasting solution for external stairs. The treading surface has a natural quarry surface: non-slip and guarantees excellent adhesion and safety to the flooring, even when wet.
