After being corroded by external factors, the lifespan of street light poles is significantly reduced, seriously affecting their aesthetics and posing safety hazards. So, in order to ensure the service life of various street light poles, what method should be used for surface treatment of street light poles to achieve better antioxidant capacity? Actually, rust prevention measures need to be taken:
The first step is to carry out galvanizing treatment.
Galvanization is also divided into hot-dip galvanizing and cold dip galvanizing. First of all, let’s talk about cold plating. Cold plating is a simple treatment through electroplating, with very little zinc, as if a film is attached. On the other hand, hot-dip galvanizing involves acid washing and 500 degree high-temperature galvanizing, and passivation if necessary. From the perspective of the washing degree of the process, hot-dip galvanizing is better, and the adhesion ability of the zinc layer is stronger, which can ensure the rust prevention period.
The second is electrostatic spraying forming.
Using polyester plastic powder with a thickness greater than 85 microns ensures a flat plastic layer, high adhesion, and UV protection. After these two treatment methods, street light poles usually do not rust for 10 years, ensuring a corrosion resistance life of over 30 years. But if cold galvanizing is used, it cannot be well expressed. In areas with high and frequent rainfall, rusting begins like it cannot even be used for years. Therefore, the main antioxidant methods for street light poles are hot-dip galvanizing and electrostatic spraying.
In summary, only by performing these two rust removal steps well can we ensure the lifespan of our various street lights. Not for making money, but to use oil lamp sticks cold galvanized, galvanized sheets, etc. This harmful practice is not advisable
