The importance and technology of "galvanization" to prolong the life of lighting poles.
Lighting poles installed on roads and in parks are exposed to rain, wind, and ultraviolet rays for long periods, making surface treatment essential to prevent rust. A representative method for this is "galvanization," which involves covering the surface of the metal with a zinc coating.
Galvanization not only protects iron from air and moisture but also ensures that if the surface gets scratched, the zinc will corrode before the iron, thereby protecting the steel. This treatment is crucial for enhancing the durability of lighting poles and reducing maintenance burdens.
However, to achieve sufficient rust prevention, proper surface preparation before galvanization is also necessary. If burrs, oil, or dirt from processing remain, it can lead to uneven coating or peeling. Additionally, measuring the film thickness and conducting visual inspections after treatment are important for confirming quality.
