Steps and copings

The porphyry steps with natural quarry surface are used for the formation and dressing of steps.The coping are elements wich border, cover and protect building parts such as walls, terraces, balconies etc.
The block steps made of solid single blocks of porphyry create a stunning effect.They are used for exteriors, the natural or flamed surface represent a trad surface which is one of the most no-slip and safe

2) Sawn and processed edges
Petrographic name Rhyolitic ignimbrite
Colour Non-dominant variable-colour grades: grey, red, red-violet, rust or mixed colours
Main processing 1) Obtained by mechanical splitting from stratified material with natural plane, variable thickness; selection of tendentially homogeneous thickness;
2) obtained by sawing fron stratified material with natural plane in calibrated thickness
