Hot dip galvanized steel tube packaging and cold galvanizing packaged with distinction

Hot dip galvanized steel tube packaging and cold galvanizing packaged with what's the difference? A lot of friends in the choose and buy when all points not clear, today we give you detailed descriptions: 1, also called hot dip galvanizing zinc, is the workpiece after oil removal, rust removal, no pollution, infiltration of surface, immediately immersed to heat the zinc in advance to melt the plating tank, the workpiece surface to form a layer of zinc plating method. Cold galvanizing is the same after oil removal, in addition to lure, dirt, infiltrates the artifacts that hangs in special on the cathode in the plating bath, use zinc anode. Connected to a dc power supply, zinc ions on the anode to cathode migration, and on the cathode discharge, make the artifacts on a layer of zinc plating layer method of hot dip galvanized steel strand. 2, hot dip galvanized coating thicker, generally is 30 - 60 micrometers, coating anticorrosion ability is higher. Cold galvanized tension by electrochemically anticorrosive coating, so to ensure good contact with zinc powder and steel, electrode potential difference is produced. In general galvanized pack with the method of hot galvanizing is more, of course, there are some choose cold galvanizing, choice of zinc in a different way, the usage of natural packaging tapes nature will also be a slight difference, so we also need to pay attention to when the choose and buy galvanized prices cheaper than electric galvanized. Electric galvanized surface coating adhesion is better than galvanized. Of hot dip galvanized coating is higher than the galvanized. Normal galvanized is 20 g single. Hot dip galvanized is 30 - less - - - - - - 40g。 Small make up: G
