Natural stone kerbs
Natural stone kerbs were usually quarried during the last century and worked by hand or machine. While most coping stones are made of bluestone or granite, smaller specimens made of porphyry or vitrified clay are also available on the reclamation market. Different traders cut the coping stones to a certain length and others conduct certain surface treatments.
Concrete coping stones are very rare on the reclamation market because their cheap price makes them very difficult to compete with.
