Porphyry kerbs are parallelepiped-shaped elements with a side height of between 20 and 30 cm. They are used for the formation of pavements, flowerbeds, steps and for the delimitation of pavements.
KERBS
It is possible to order both natural plane and beads with sawn head and/or side (machined with diamond saws to obtain precise geometric shapes).
