Porphyry stairs

We provide our customers with customized elements to create porphyry stairs of different types and sizes, for both exterior and interior. A porphyry staircase excellently resists over time without wearing out and, if done in a workmanlike manner, can become a valuable decorative element.
We offer the customer numerous processes to ensure an exclusive final realization, as well as personalized support from our Sales Department.

External porphyry stairs: aesthetics, resistance and anti-slip effect

Each natural stone staircase is unique, in fact it can be made with different processes depending on the structural and aesthetic needs. This is why we offer our customers:

  • surfaces with natural, flamed, brushed top
  • special processing of the sides, such as sawn, flamed or split
  • different sizes of the various elements, to run, single pieces, goose or massive
  • different colors of the material thanks to our extraction fields

The result will be a unique and personal realization.
Precisely because of the uniqueness of each creation, we recommend that you contact our Technical Department directly for all the information and advice relating to the staircase to be built.

Furthermore, one of the main characteristics of Trentino porphyry, if kept natural, is the rough surface. The anti-slip effect makes this material ideal for the construction of steeply sloping roads, even subject to frosts. This also happens for the external porphyry stairs: the rough steps reduce the risk of falls in case of rain, but also of ice or snow.

Installation and construction of the external porphyry stairs

The installation of external stairs with porphyry steps depends mainly on the type chosen and the correct construction of the rough concrete staircase. It is of fundamental importance the correct measurement of the steps and any shapes, recommended in particular for out-of-square or gooseneck steps.

The installation generally takes place with cement mortar, “dirtying” the lower part of the steps with cement grout which acts as an adhesion between the step and the mortar. Then we move on to grouting with professional grout or putty.

Maintenance and cleaning

Cleaning the porphyry stairs is simple, in fact only water or the use of a pressure washer is required to clean the stone. Instead, we do not recommend the use of detergents or acids.
