hot-dip galvanized and cold galvanized

February 28, 2019

The galvanizing pole divided into hot-dip galvanizing and cold galvanizing. The hot-dip galvanizing melts the zinc, and then the pole passes through the zinc liquid to form a galvanized layer on the surface. The cold galvanizing is that the plating is the steel. Put into the electrolyte containing zinc, electrify and electroplating, so that zinc is deposited on the surface of the plating layer, its zinc content is very low.

Firstly, from the appearance of the pole the surface of the hot-dip galvanized pole is shiny and silver-white, and the surface of the cold galvanized pole is black and white.
Second, through professional instrument testing, the thickness of the zinc layer is generally measured by a layer thickness gage. The zinc layer thickness of the galvanized pole is less than 10 microns, and the hot-dip galvanized steel grid plate is above 70 microns.
Thirdly, judging from the price of steel pole, hot-dip galvanized steel gratings of the same steel grating size are higher than cold galvanized gratings because of its high zinc content and high prices.

Fourth, see the weight, or the principle of the amount of zinc, hot-dip galvanizing than the amount of zinc on the cold galvanized steel corresponding to the same size of the size of the weight is also high
