High Quality Street Light Housing Supplier Introduces Finish Paint Details For Street Light Poles

Posted by ninghai on December 1st, 2022

The commonly used anti-rust process for street lamp poles is hot-rolled steel plate + hot/cold galvanized + sprayed plastic. The theoretical life of the lamp pole after qualified galvanized sprayed plastic processing is 15-20 years, which means that the street lamp will be at least 15 years old. The surface paint will not fade or rust. The theory is the theory after all. Can this effect be achieved in actual use? The following High Quality Street Light Housing Supplier introduces the advantages of topcoats for street light poles.

Street light poles will hardly rust after being cold/hot galvanized (except for trachoma during lamp pole welding), then the only factor that affects the appearance of street lights is exterior paint. Street light poles will be processed after galvanizing. The last anti-corrosion coating process is plastic spraying. The plastic powder used in spraying is outdoor plastic powder. The outdoor plastic powder has the characteristics of high hardness and strong adhesion. The effect has been further improved, but after actual use, it is found that the service life of the plastic powder cannot reach 10 years, let alone 15-20 years. Take a better outdoor high-gloss plastic powder for example, after spraying The surface of the latter pole is bright and smooth, but after three years of outdoor use, the luster of the pole surface will gradually dim and then begin to change color and peel off the paint. This is a good plastic powder, and poor-quality plastic powder will change completely within a year. The biggest disadvantage of outdoor plastic powder is its poor aging resistance.

There is a way to extend the life of street lamp surface paint so that it can maintain the original color for a long time without changing color and chalking. If galvanizing is for rust prevention, then plastic spraying is for aesthetics. If the rust prevention is done, the aesthetics is achieved, then adding a layer of the protective film is perfect. The weather resistance of outdoor powder is very poor. If it can be encapsulated with outer paint with super weather resistance, it can keep its original color for a long time. However, this kind of outer paint is not difficult to find, it is "fluorocarbon paint", Fluorocarbon paint has excellent anti-corrosion performance, maintenance-free, strong adhesion, long weather resistance, etc., coating the fluorocarbon paint on the plastic powder outer layer of the light pole can play a very good protective effect, making it It is not a problem to maintain the gloss of the exterior paint on the surface for more than ten years.
