With the construction of roads, the demand for signposts is constantly increasing, and there are more and more traffic signpost manufacturers. However, many people still have many blind spots regarding signs and signposts. Today, Qixiang Traffic Signpost Manufacturer will talk to you about double-column and single-column signposts.
Ⅰ. Manufacturing Process of Single-Column and Double-Column Signposts
The steel poles are treated with internal and external hot-dip galvanizing for corrosion protection. The galvanizing process involves pickling, hot-dip galvanizing, water washing, phosphating, passivation, etc. The galvanized layer has a smooth and beautiful surface, and the zinc layer thickness reaches more than 86μm, which meets the national standard GB/T13912-92. The adhesion of the galvanized layer meets the requirements of GB2694-88, and the corrosion protection life is greater than 20 years.
Ⅱ. Significance of Single-Column and Double-Column Signposts
1. Load-bearing and Fixing Function:
As the direct support structure for signs, warning lights, and directional signs, the signpost must stably bear the weight of the sign and resist erosion from natural forces such as wind, rain, snow, and sandstorms.
2. Ensuring Clear Information Transmission:
The height and installation angle of the signpost are determined by design specifications, placing the sign at the optimal visual height (usually matching eye level or slightly higher), ensuring that pedestrians and vehicles can clearly identify the information from a distance and avoiding blind spots caused by improper installation.
3. Enhancing Scene Order:
Standardized signposts make the signage system more organized, avoiding haphazard installation methods.
Ⅲ. Materials of Single-Column and Double-Column Sign Poles
Highway sign poles utilize a single-bending or flange-jointing technique, making installation more convenient and flexible. The pole surface undergoes degreasing, phosphating, and hot-dip galvanizing, ensuring a service life of over 20 years. Outdoor electrostatic powder coating is used for the pole’s appearance, ensuring color harmony with the surrounding environment. Both the inner and outer surfaces of the pole are hot-dip galvanized for corrosion protection. If needed, surface finishing can be achieved using spray painting techniques depending on the actual application environment.
