What is the difference between hot dip galvanizing and cold galvanizing?

As the price of solar street lights continues to drop, customers pay more attention to quality when purchasing. Many light pole manufacturers claim that the solar street light poles they produce are processed by galvanizing process, so what is the difference between hot-dip galvanizing and cold galvanizing of solar street light poles? Among them, cold galvanizing is also called electro-galvanizing, and Jindou Lighting, a street light pole manufacturer, will analyze it for everyone.

First of all, let’s take a look at the difference between the finished solar street light poles produced by hot-dip galvanizing and cold-galvanizing. The hot-dip galvanized layer is thicker and the thickness is not uniform; although the electroplating layer is uniform, the thickness is very thin. The thickness of the hot-dip galvanized layer is dozens of times that of the cold-dip galvanized layer. This is why more and more street light pole manufacturers choose hot-dip galvanizing.

Secondly, from the perspective of function, the cold galvanizing process is used for the anti-corrosion of various steel products and structures. However, the amount of galvanizing is very small, only 10-50g/m2, and its corrosion resistance is much different than that of hot-dip galvanizing. Of course, in terms of price, it is also much different from the street light poles produced by hot-dip galvanizing, which is why some customers can buy galvanized light poles at ultra-low prices.

In addition, the street light pole manufacturer Qinggu Company reminds everyone that although they are all galvanized, the effect of cold galvanizing is at most similar to that of anti-rust coating. The light poles produced by this process are easy to rust and fall off. Although the hot-dip galvanized pipe is also rusted, it can meet the technical and hygienic requirements in a long period of time.

After understanding the difference between hot-dip galvanizing and cold-galvanizing of solar street light poles, everyone needs to pay more attention when purchasing and buy more high-quality street light poles.
