Most granite road edge stone processing will be near the top corner of the road cut a small corner, so that the top corner will not be too sharp, to avoid injury to pedestrians or traffic safety. Engineering design is different, chamfering size is not the same, generally the conventional 1 cm angle, there are also 2 cm, 3 cm and other different sizes of angle.
In addition to the right angle cutting described above, it can also be processed into rounded curbstones. As shown in the figure below, it is a circular chamfer, which can be seen as a quarter arc from the side.
We are committed to providing high quality granite stone for real estate, garden, curtain wall, municipal engineering projects.
