The key and importance of solar street lights as lighting equipment for public facilities and traffic roads is to ensure driving safety. The topcoat on the solar light pole can ensure that the solar street light maintains its color in different environments and prevents rust. Ash content is an important factor in choosing the top coat of solar light poles, so what kind of coating is used for solar light poles? Here is Sallen Lebekan's sharing:

The commonly used anti-rust technology for solar street light poles is hot-rolled steel sheet + hot/cold galvanized + spraying + protective film: After cold/hot galvanizing treatment, the solar street light pole will hardly rust (unless there is trachoma welded on the pole), so the only factor that affects the appearance of the street light is the exterior wall paint. After the solar light pole is galvanized, the last layer of anti-corrosion coating will be sprayed. Outdoor plastic powder or outdoor glitter plastic for spraying is better, but after actual use, it is found that the service life of outdoor plastic powder cannot reach 10 or even 20 years. Outdoor bright powder plastic powder can be used outdoors for 3 years, after which the luster of the surface of the solar light pole will gradually darken, then change color and start to color. This is a good plastic powder, but the biggest disadvantage of outdoor plastic powder is resistance Poor aging. Therefore, it is necessary to add a protective film on the surface at this time. Galvanizing is to prevent rust. Plastic sandblasting is for aesthetics, rust prevention and improved appearance, but adding a protective film is perfect. Outdoor powders have poor weather resistance, and if they can be packaged with super weather resistant coatings, they can maintain their original color for a long time. However, this paint is not difficult to find, it is a "fluorocarbon paint". Fluorocarbon coatings have excellent corrosion resistance, maintenance-free, strong adhesion and good weather resistance. Fluorocarbon coatings can be applied to the plastic powder outer layer of solar street light poles to provide good protection. It is not a problem to maintain the surface gloss for more than ten years.
