The difference between light, cold galvanized and hot dip galvanized

Many clients ask us questions about the galvanized, cold galvanized and hot dip galvanized how to distinguish, hot dip galvanized, after all, 20 years does not rust, cold galvanizing is only 2 years of time, high lamp factory prepared the difference between the two small make up today for your reference.

high lamp cold galvanizing is the use of electrolytic equipment light pole to be included in the composition of zinc salt solution, and connect the cathode electrolytic equipment, across the tube placed zinco, connected to the anode electrolytic equipment, power supply is connected using current from the positive to the negative directional moving deposits a layer of zinc on the pipe fittings, cold plated pipe is galvanized after processing first, so also known as electric galvanized. Cold galvanized coatings mainly through electrochemical principle for corrosion protection, so must ensure that the full contact of zinc powder and steel electrode potential difference, so it's very important to steel surface treatment.

light, hot dip galvanized is put high lamp in the zinc pool, is the hot zinc liquid, into a liquid, jiang room light pole which drenched, will attach a layer of zinc in the surface of light pole, is a process of room change.
