Why do street light poles need to be painted?

After the street lamp pole is treated by cold/hot galvanizing, it will hardly rust (except for the sand hole in the street lamp after welding), so the factor that affects the appearance of the street lamp is the outer paint. After the street light pole is galvanized, spray plastic is used in the subsequent anti-corrosion coating process. The plastic powder used for spraying is on-site plastic powder with high hardness and strong adhesion. The appearance and anti-corrosion effect of the plastic-sprayed lamp poles are further improved, but after actual use, it is found that the service life of the plastic-sprayed powder is less than 10 years, let alone 15-20 years. Taking the high-gloss plastic powder on site as an example, the light pole looks smooth after spraying, but after three years of on-site use, the gloss of the light pole will gradually darken, and then begin to change color and discoloration. painting. This is a good plastic powder. Inferior plastic powder will be completely replaced within one year. The biggest defect of on-site plastic powder is poor aging resistance.

There is a way to prolong the service life of street lamp surface paint, so that it can keep its original color for a long time without discoloration and chalking. If galvanizing is to prevent rust, the spray should be aesthetically pleasing. If the effect of rust prevention and beauty is achieved, a protective film should be added to achieve a better effect. Outdoor powder has poor weather resistance. If it can be encapsulated with an ultra-weather-resistant exterior paint, it can maintain its true color for a long time. This exterior paint isn't hard to find, though. It is "fluorocarbon paint". Fluorocarbon paint has the characteristics of excellent corrosion resistance, maintenance-free, strong adhesion, and long weather resistance. The application of fluorocarbon coating can play an important role in the outer layer of the plastic powder of the lamp pole. It has a good protective effect, and it is not a problem to maintain the appearance of the coating for more than ten years.
street light pole problem

Street light poles and traffic light pole products are used to support signal lights. It is made of steel. After manufacture, it is hot dip galvanized. The manufacture of traffic light poles must comply with national standards and should be manufactured according to the actual conditions of the environment and roads. Signal lights and light poles guide traffic and avoid traffic hazards.

The shape of common parts: round rod, cone rod, octagonal rod, etc. The appearance of all components must be beautiful, concise and harmonious.

1. All welding is required, and the whole electrode is manufactured according to the standard;

2. The bar is made of high-quality steel, and the bar body is made of a large CNC bending machine;

3. The main body of the steel bar should be free of lack of welding and projection welding;

4. The appearance of the main body and the cross arm must be sprayed;

5. The normal color is white, which can be customized according to customer requirements;

6. Suitable for weak current engineering, monitoring engineering, municipal and road monitoring;
