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
