What is Delineator
The column contour mark is composed of a column and a reflective material. The column is a triangular section with rounded corners, and the top is oblique to the traffic lane. In recent years, the development and changes of column outline markers are very large. It is a traffic safety facility set along the edges of both sides of the road, used to display the outline of the road boundary, guide vehicles to drive normally, and have retroreflective performance. In terms of function, the delineator is a line of sight guidance facility. Contour markers can reflect the lights of the car to enable the driver to understand the road conditions ahead; the contour markers set on both sides of the road serve as warning signs for the boundary of the road and can also play a role in guiding and warning the driver at night, which is very good The ground ensures the safety of passing vehicles.
Classification of Delineator
Cement column
Early column base materials were cement prefabricated parts, which were cheap in cost, but had two major disadvantages: (a) When the vehicle hits, it will cause a greater secondary damage to the vehicle; (b) the color is not obvious, and the reflector is not easy to adhere to the cement surface .
Steel plate
The column is made of steel plate, and the surface is galvanized and painted. In this case, the reflector can be easily connected to the surface of the column, but there are three disadvantages: high cost, greater secondary damage, and easy to rust.
PVC engineering plastics
PVC engineering plastic substrate is formed by mechanical mold, with stable formula, uniform wall thickness, smooth surface, not easy to age, and no secondary damage. The production speed is fast and the cost is low.
Flexible column outline mark
The elastic material is applied to the column contour mark to solve the situation that the column contour mark is damaged or crashed. The base material of the elastic warning column is made of engineering plastics with high elasticity and weather resistance.
