After PVC coat process, black or galvanized welded mesh can be with high corrosion resistance. Especially , the galvanized welded mesh is coated with two layers of PVC and Zinc which is tightly bonded to the wire by a heat process. They are double protection. Ne samo, da vinilni prevlečni tesnilo ščiti žico pred vodo in drugimi jedkimi elementi, ampak je tudi osnovna mreža zaščitena tudi z dobrim cinkovim premazom. PVC coat make the welded mesh longer working life, and more beautiful with different colors.
Weld mesh gabion are manufactured from cold drawn steel wire and strictly conform to BS1052:1986 for tensile strength. It is then electrically welded together and Hot Dip Galvanised or Alu-Zinc coated to BS443/EN10244-2, ensuring a longer life. Mreže so lahko nato organski polimer, prevlečen tako, da varuje proti koroziji in drugim vremenskim učinkom, še posebej, če se gabije uporabljajo v slanih in zelo onesnaženih okoljih.
