The column outline mark is composed of a column and reflective material. The column has a triangular cross-section with rounded corners, and the top is diagonally facing the traffic lane. The column of the outline mark is white, and there should be a long black mark on the upper part of the column. There is a retroreflective material in the middle of the black mark. The retroreflective material should not fall off. In recent years, the development of column outlines has changed greatly. Cement columns
. The early column base material was cement prefabricated parts, which was cheap but had two major shortcomings. When the vehicle hits, there will be greater secondary damage to the vehicle. (b) The color is not obvious, and the reflector is not easy to adhere to the cement surface.
