In the planning of urban roads, landscape gardens, or residential communities, kerbstones play a crucial role—not only do they separate roadways from sidewalks and green spaces, but they also enhance the overall cityscape and elevate the urban aesthetic. Serving as the silent sculptors of modern urban order and beauty, kerbstones are indispensable in city construction.
Types of Kerbstone Materials
The most common kerbstone materials available on the market today include natural stone, concrete, and engineered stone. Among these, natural stone is the most widely used, with popular choices such as granite, marble, limestone, and bluestone.
Granite kerbstones are particularly favored for their natural textures and colors, which offer a visually appealing and elegant look. They are also known for their high hardness, wear resistance, and excellent compressive strength, making them capable of withstanding heavy vehicle traffic and pedestrian use. Granite is especially suitable for areas with high traffic volume and provides excellent weather resistance and corrosion durability, maintaining performance even under harsh environmental conditions. These properties make it ideal for various applications such as road projects, bridges, and landscaping.
Kerbstone Cutting and Chamfering
Freshly processed kerbstones typically start as rectangular blocks with four sharp edges. However, many kerbstones seen in urban settings have slanted or rounded edges—this modification is what’s known as chamfering.
Traditional kerbstone cutting and chamfering methods include semi-automatic machines and manual processing. The semi-automatic process uses infrared cutting machines. First, rough stone blocks are sliced into the required thickness. Then, they are cut into the desired dimensions. By adjusting the tilt of the saw blade, a slanted edge (chamfer) can be made. However, this method is only suitable for angled chamfers—not rounded ones—and the overall efficiency is low. During the process, operators must frequently stop the machine to adjust parameters, load/unload materials, or use forklifts for handling. Additionally, the cutting heads experience significant wear and tear, which increases production costs.
Manual chamfering is most commonly used for rounded edges. Small 1-2 cm quarter-round edges can be made using a handheld grinder with repeated polishing. For larger 5 cm+ round edges, workers must grind them slowly and carefully by hand while maintaining a consistent arc to ensure uniform alignment. This process is both labor-intensive and time-consuming, and prone to inconsistencies.
