  • Hot dip galvanizing, also known as hot dip zinc, is the method of forming a layer of zinc coating on the surface of the workpiece after oil removal and rust removal, showing a clean and infiltrating surface, immediately immersed in the plating tank of zinc melting in advance. Cold galvanizing is the same after the removal of oil, in addition to lure, showing no pollution, infiltration of the workpiece hung into a special electroplating tank on the cathode, the anode with zinc. Switch on the DC power supply, zinc ions on the anode migrate to the cathode, and discharge on the cathode, so that the workpiece is coated with a layer of zinc layer hot dip galvanizing method.

  • Six features of spray blade stabbing rope

  • It is best to use special columns to fix the barbed rope installation, because the standard column is not only beautiful shape and better protection effect.

  • Both sides of the galvanized welding net exposed can not be more than 2mm, so as to be qualified. And in the welding mesh of each warp and weft wire cross place, must be welded very firm, and if you want to welding very firm, both sides must have some warp and weft wire out, and the length must be controlled within two millimeters. From the mesh distribution is not uniform, galvanized is not uniform, but also to see whether the welding mesh is qualified standards.
