Cold galvanizing and hot-dip galvanizing are two common anti-corrosion treatment methods used to protect street light poles from oxidation and corrosion. Both cold galvanizing and hot-dip galvanizing can be used to increase the durability and service life of galvanized street light pole. The difference between cold galvanized street light poles and hot-dip galvanized street light poles will be introduced below.
1. Technological process:
-Cold galvanizing: Cold galvanizing is the process of immersing metal materials in a solution containing zinc, and attaching a zinc layer to the metal surface through electrochemical reactions. This process does not require heating, therefore it is called cold galvanizing.
-Hot dip galvanizing: Hot dip galvanizing is the process of immersing a metal material in molten zinc and attaching a zinc layer to the metal surface through a chemical reaction. This process requires heating, hence it is called hot-dip galvanizing.
2. Coating thickness:
-Cold dip galvanizing: The coating thickness of cold dip galvanizing is usually thin, usually between 5-15 microns. This is because the process of cold galvanizing is relatively simple and cannot form a thick zinc layer on the metal surface.
-Hot dip galvanizing: The coating thickness of hot-dip galvanizing is usually thick, generally between 45-100 microns. This is because the process of hot-dip galvanizing is relatively complex and can form a thick zinc layer on the metal surface.
3. Anti corrosion performance:
-Cold galvanizing: Cold galvanizing has relatively poor anti-corrosion performance, thin coating, and is easily affected by mechanical wear and chemical corrosion. Therefore, the service life of cold galvanized street light poles is relatively short.
-Hot dip galvanizing: Hot dip galvanizing has good anti-corrosion performance and a thick coating, which can effectively prevent metal materials from being affected by oxidation and corrosion. Therefore, the service life of hot-dip galvanized street light poles is relatively long.
4. Appearance effect:
-Cold galvanizing: The appearance of cold galvanizing is relatively bright, and the metal surface is smooth and uniform. This makes cold galvanizing suitable for some occasions with high appearance requirements.
-Hot dip galvanizing: The appearance of hot-dip galvanizing is relatively dark, and the metal surface has a certain degree of roughness. This makes hot-dip galvanizing suitable for some occasions that do not require high appearance but require high anti-corrosion performance.
In summary, there are certain differences between cold galvanizing and hot-dip galvanizing in terms of process, coating thickness, anti-corrosion performance, and appearance effect. When selecting street lamp posts, suitable anti-corrosion treatment methods can be chosen based on specific usage environments and requirem
