The Galvanizing of cold and hot difference

July 31, 2018

The galvanized chain link network is divided into a hot-dip galvanized chain link network and a cold galvanized chain link network. The difference between the two is: hot-dip galvanizing is the immersion of zinc in hot liquids, production speed, coating thickness, but Not uniform, the market allows a minimum thickness of 45 microns to 300 microns.
Hot-dip galvanized chain linking nets are placed in liquid zinc in a manner of high-temperature heating. A series of chemical reactions take place at high temperatures and with the action of catalysts. Finally, a thick zinc layer is attached to the surface of the hook gauzes. The hook chain net obtained by the hot-dip galvanizing method is bright, very beautiful, and highly corrosion-resistant.
Cold galvanized chain hook net is to put the workpiece directly into the zinc liquid, and then use the principle of the electrolyte to make zinc adhere to the surface of the hook chain net. The zinc layer on the surface of the cold galvanized chain link net is relatively thin, compared with the hot dip galvanizing. The color is brighter, but over time it may get rusty.
The surface color of cold galvanized hook chain net and hot galvanized hook chain net is silver white, which is almost indistinguishable, but if you look closely you will find that the galvanized chain link net is brighter in color and the hot galvanized hook chain net is darker in color. Hot-dip galvanized chain link network is thicker than the zinc layer of galvanized hook chain network. The difference is in product characteristics. The corrosion resistance of galvanized chain link network is relatively poor. Generally, after 5-7 months, the surface will have rust. trace. Hot-dip galvanized chain link net is used for 10 years without rust on the surface. The difference in the price of hook flower network, from the price of factory chain flowers can be seen, the general hot-dip galvanized hook chain network than the price of zinc plated hook flower network is higher.
