The anti-corrosion of the traffic sign pole is hot-dip galvanized, galvanized and then sprayed with plastic. The service life of the galvanized sign pole can reach more than 20 years. The sprayed sign pole has a beautiful appearance and a variety of colors to choose from.
In densely populated and complex places, prosperous commercial and trade areas, and security checkpoints in and out of the city, it is often seen that the high-speed ball video surveillance pole adopts the cone tube pole process structure. Let’s talk about the advantages of using the tapered tube vertical rod process for high-speed ball installation.
The advantages of adopting the tapered tube vertical rod process for high-speed ball installation are simply summarized in three points: simple production process, high strength, and relatively beautiful appearance.
1. The production process is simple.
Taper tube vertical rods are often produced by rolling steel plates and then directly to the welding process. There is almost no requirement for welding accuracy, and the welding is beautiful and reliable. At the same time, the welding seam is not directly stressed, and the durability and reliability are high. However, the two-stage column pipe vertical rod needs to weld an adapter between the two-stage straight pipes with different thicknesses, which requires high welding technology. In addition, the welding seam directly bears the gravity of the upper straight pipe, and the welding quality is not high and it is easy to cause hidden dangers.
2. High strength.
Because the tapered tube vertical rod adopts an integrated process, the axial and lateral forces are relatively uniform, while the two-stage column tube vertical rod requires at least three parts to be welded. The force is not uniform, so the strength is not as good as the former.
3. Relatively beautiful.
The top-thin and bottom-thick shape is more in line with the aesthetics of most people, and the straight tube standing too high can easily make people feel top-heavy and unstable, resulting in the illusion of insecurity.
2. Introduction to the production materials of traffic sign poles:
At present, the bottom plate of traffic sign poles on expressways is generally spliced with aluminum plates, and the reflective film is of high-strength grade (that is, the third grade in “Technical Conditions for Highway Signposts for Highway Traffic” JTJ279-1995).
