We offer the best product range of Hot Dip Galvanizing.
Because the new coating can be dissolved in acid and strong alkali environment, the hot galvanizing layer is only suitable for atmospheric and natural water environment. The galvanized layer is prone to slight electrochemical corrosion when it comes into contact with air and who. Where the air is relatively clean, the life of the galvanized layer will increase, while in coastal areas and industrial pollution areas, the life of the galvanized layer is relatively short. In addition, there have been a lot of data on the durability test of hot galvanizing layer. The data show that the thicker the galvanized layer, the longer the durability, and the durability is proportional to the thickness of the galvanized layer. Of course, according to the test environment, there are some differences in data.
I don't know how many people know abouthot dip galvanizing. This is actually a more complicated change, and it refers specifically to the reaction of molten metal with iron, its basic body, into an alloy layer. Then the basic body and the coating are combined.
The reason for such a complex change is that hot dip galvanizing has obvious advantages. It is not just the plating is very pure and fresh, and its adhesion is very strong, can use for many years without too big change, also is that so many people willing to pay for such a big cost to make him and the reason why spend high price to buy it.
Under normal circumstances, we used in the industry that some steel material, if put them in the sea, or in the atmosphere, due to the high salinity of the water or some other factors, they generally relatively large degree of corrosion, and corrosion for these is greatly harm the service life of steel materials, so in order to change this phenomenon, hot dip galvanized just arises at the historic moment. His presence can greatly ensure the steel will not corrode, can significantly extend the service life of common steel material, so that the continuing people attach importance to this technology in recent years.
hot dip galvanizingis what we now know, can be as much as possible, one of the best ways to delay the service life of steel materials, only surface after cleaning of steel material, and then, after activation is in liquid zinc, happy and let them between reaction and diffusion, form a more perfect material.
