Fence mesh is welded with metal mesh to support

The fence net is a grid gate welded to a supporting structure with a metal mesh to prevent people and animals from entering the alert area. Fences and barriers should be provided at both ends of the expressway and the first-class passenger-only highways. To avoid illegal annexation of road land.

One of the anti-corrosion methods of fence nets by manufacturers: zinc steel fence dip plastic is a plastic coating process, which is a method of coating plastic with powder on the base metal, which originates from the vulcanized bed method. The vulcanization bed was first used in the Winkler gas-fired furnace for the decomposition of petroleum touch, thereby developing a solid-gas two-phase touch process, and then gradually used in metal coating.

Dip molding is to uniformly spray plastic powder on the metal by heating the metal to form a plastic film, or heat the dipping solution into the metal parts to cool the plastic and cover the metal surface. This process is widely used because it does not require molds, low processing costs, simple molding, and can process various shapes.
