Processing Mode:加工方式

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 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 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.
7.The zine layer of hot galvanizing can keep long than cold galvanizing.


Hot galvanized highway guardrail. 热镀锌护栏
Normally, hot dip galvanization is the present widespread application used in anti-corrosion for zinc coating W-beams barriers. SHITENG hot galvanized highway guardrail are widely use for expressway, Parking lot, Scenic area and countryside safety system. The surface is hot galvanized and have the feature of anti-corrosion, anti-aging and durable. That
