Curbstone machines are machines used in the construction industry to produce curbstones or concrete borders. These machines are designed to make the process of producing curbstones faster and more efficient. They can be used to produce different shapes and sizes of curbstones depending on the requirement of the project. Curbstone machines are operated by either hydraulic or pneumatic systems and can be fully automated or semi-automated. The raw materials used in producing the curbstones include concrete, cement, water, and aggregates. Curbstone machines are available in a range of models and sizes to cater to the varying needs of customers and their projects.
