Delgorsa Porphyry Stair Treads

The Delgorsa Porphyry Stair Treads with natural surface is obtained from raw quarry slabs of different thicknesses and dimensions.

They can have split ends or sawn sides: The former are obtained through a mechanical cutting and selecting the different thicknesses. The latter are obtained sawing the slabs and then calibrating the visible sides in order to obtain a more uniform thickness.

General evaluation of the product. The natural surface products are more rustic and are advisable for external stairs, gardens and small walls, where the aspect is quite rustic and there are acceptable tolerances. The natural surface products, whose measures are modified with machines, can be effectively used outdoor installations highlighting the physical features of the material, without altering the original composition.
