light pole is the most common anti-rust process is hot rolled steel plate + hot/cold galvanized, plastic spraying. Qualified after galvanized and plastic spraying, the theory of life of the light pole is 15 -- 20 years, that is to say, the surface of street light lacquer for at least 15 years will not fade or rust. After dealing with the cold/hot dip galvanized, lamp posts almost no rust ( In addition to lamps after welding of sand hole) , so the only factors will effect the beauty of the street lamp is external coatings. After to galvanized lamp light pole, the last of the anti-corrosion coating process is using spraying plastic. Spray is used in the plastic powder with high hardness, adhesion in the field of plastic powder. By spraying plastic processing after the appearance of the lamp and anticorrosive effect has been further improved. However, in actual use, found that the service life of plastic powder can't up to 10 years, let alone 15 For 20 years. Field high gloss plastic powder, for example, after spraying the appearance of the lamp is bright and clean, but at the scene to use three years later, the luster of the light pole will gradually dim, and then began to change color and paint. This is a good plastic powder. Inferior plastic powder will completely replace in a year. The biggest defects of plastic powder is its aging resistance is poor. There is a way to extend the service life of coating the surface of the lamp, make its can maintain the original color for long, and will not change color and pulverization. If the galvanized to prevent rust, spraying to beautiful. If the rust, beautiful, should add a layer of protective film to achieve perfect effect. Outdoor weatherability powder is very poor. If you can use a kind of exterior wall coating with excellent weather-resistance for encapsulation, is to be able to maintain its natural color for a long time. But, this kind of exterior wall coating are not hard to find. It is 'fluorocarbon paint'. Fluorocarbon coating has excellent corrosion resistance, maintenance-free, adhesion, long weatherability, etc. In the light pole plastics powder coated with fluorocarbon coating on the outer can play an important role. Very good protection effect, to keep the appearance of the coating more than a decade of gloss is not a problem. The service life of lamp posts are mostly long-term, correct and high-quality technology will make whole life once and for all.
