According to the difference of the processing mode, the galvanized fall into cold galvanized and hot galvanized. Normally, the highway guardrail is hot galvanized products.The difference between hot galvanizing and cold galvanizing:

1. The corrosion resistance of the hot galvanizing is dozens of times of cold galvanizing.
2. The method of operation is the difference: which the hot galvanizing means bathed the steel into 480-500 degree zine liquid, but the cold is zinc plated through electroplating or other methods at normal temperature.
3. The thickness of the galvanized layer is different, the thickness of hot galvanizing is much greater than that of cold galvanizing.
4. The surface is different, cold galvanizing appearance is more smooth than hot galvanizing.
5. Price is different, hot galvanizing is more expensive than cold galvanizing.
6. Cold galvanizing just be plated only one side, but hot galvanizing is all plated.
