What are the anti-corrosion treatments of the poles?

China is a populous country and there is a great need for street lighting. Due to the roads extending in all directions, people invented the street lamps, and the light poles currently used on the market are formed by the disposable roller of Q235 steel. But the long-term use of it is rust, also known as iron oxide, alias iron oxide, reddish brown. Today, Xiaobian explains how to protect the streetlights from corrosion.
First, electroplating

In the outdoor lighting industry, electroplating we call it zinc spray can also be called cold plating.

The process of plating a thin layer of other metals or alloys on certain metal surfaces by electrolysis is a process of attaching a metal film to the surface of a metal or other material by electrolysis to prevent oxidation of the metal (eg, Corrosion), improve wear resistance, electrical conductivity, light reflectivity, corrosion resistance (copper sulfate, etc.) and enhance aesthetics. Electroplating requires acid washing of the surface of the oxide film and impurities, so that the surface can be better adsorbed. However, due to the limited length of the lamp post, the quality of the material, the composition of the plating solution, the temperature, the current density, the energization time, the stirring strength, the precipitated impurities, the power waveform, etc. all affect the quality of the coating. In addition, we found that its anti-corrosion performance is general, but its low price allows some people to use it. The way to distinguish it is to see its color is dark yellow.

Second, hot-dip galvanizing

Everyone should be familiar with this method. Generally speaking, he will talk to him when selling or introducing. Hot-dip galvanizing, also known as hot-dip galvanizing, is a method in which steel members are immersed in molten zinc to obtain a metal coating. In general, the poles will use this anti-corrosion treatment.
