Diffraction between HDG and GI
HDG: Also called hot dip galvanized and hot-dip galvanized: is an effective way of metal corrosion, mainly for various sectors of the metal structure facilities. Is immersed steel rust after about 500 ℃ melted liquid zinc, steel member attached to the surface layer of zinc, which serve the purpose of preservation. Cold galvanized: is galvanized, zinc less, only 10-50g / m2, so is the use of electrolysis or other parts of the metal surface of the material attached to a metal film craft. The formation of uniform, dense, good adhesion of the metal layer process can serve to prevent corrosion, improve the wear resistance, electrical conductivity, reflectivity and enhance the aesthetics and so on. HDG and GI diffrence: 1, Different corrosion resistance, hot-dip galvanizing cold galvanizing several times. 2, On the way different jobs: HDG is 450-480 degrees in the molten liquid zinc plated zinc plating is cold at room temperature by plating zinc plating or other methods. ...
