Characteristics include high strength,strong guidance,and good protective performance.Made from high-density granite,it can withstand occasional vehicle impacts.Its vertical face and top usually form a distinct angle,both guiding rainwater runoff and serving as a visual warning to drivers.The simple design allows for easy construction and low maintenance costs.
Height ranges between 300mm and 500mm,much lower than pedestrian railings.The cross-section is often L-shaped or inverted T-shaped,with a buried base ensuring stability.Length is usually standard(e.g.,1 meter per piece),installed with tight joints.The surface is often flamed or axed to increase friction and weather resistance.
Widely used on curves and intersections of urban roads,toll plaza areas of highways,parking lot boundaries,and areas within parks requiring vehicle-pedestrian separation.It effectively enhances road safety and protects pedestrians from vehicles.In landscape design,it can also clearly demarcate different functional paved areas.
