Is divided into hot-dipped galvanized welded wire mesh and electric galvanized welded wire mesh
Characteristics of hot dip galvanized welded wire mesh
Hot dip galvanized welded wire mesh is also known as hot-dip galvanized welded wire mesh, hot dip galvanized welded wire mesh for chemical treatment of the welded wire mesh, belongs to the electrochemical reaction. He is the zinc ingots melted at high temperatures, in put some auxiliary materials, and then dipped galvanized metal structure slot, so that a layer of zinc metal components attached layer. Hot-dip galvanizing of welded wire mesh under the conditions of the hot-dip galvanized on the surface, hot-dip galvanizing the advantage of his strong anti-corrosion, galvanized layer adhesion and hardness of better is not easy to come off, use a long time.
Hot dip galvanized welded wire mesh process
→ → Roberts deal with low-carbon steel wire welded into a network → heating → cooling to the required temperature of hot-dip galvanizing → → cooling → storage
Electro-galvanized welded wire mesh
Electro-galvanized welded wire mesh to implement the working principle of:
Also known as electro-galvanized cold galvanizing is the use of electrolysis equipment will work piece through the degreasing, pickling ingredients post-zinc salt into the solution, and connect the negative terminal of electrolytic device; in the workpiece opposite the place of zinc plate connected to the electrolysis device cathode, connected to power, the use of current from the cathode to the anode of the directional move will be a layer of zinc deposited on the workpiece.

The characteristics of electro-galvanized welded wire mesh
Electro-galvanized welded wire mesh, that is, the zinc salt solution through electrolysis, to the plating on the coating, in general do not have heating, a very small number of zinc encountered humid environment is very easy to fall off.
Cold galvanizing is the physical address, only brush the surface layer of zinc, zinc coating so easy to fall off.
Cold galvanizing is the electro-galvanized, only 10-50g/m2, its own resistance to corrosion than hot-dip galvanized far too small.
Use of zinc prices is relatively cheaper.
