The service life of welded wire mesh is a constant concern of everyone, then what kind of welded wire mesh is selected to meet our requirements? As to this problem we need to analyze from two aspects, the service life, and the price. Electro-Galvanized Welded wire mesh is divided into two types: Galvanized before welded and Galvanized after welded.
Galvanized before welded the metal wire used for as re-drawn wire. This wire is electroplated by electroplating. After many drawing, the zinc content on the surface of the wire is little, and the wire welding points are not treated with corrosion, so the service life of the wire is relatively short, and it is generally 3-5 years under outdoor conditions.
After welding, the wire used by the welding wire is a black wire, and the wire mesh is placed in the galvanizing equipment for galvanizing corrosion treatment. The amount of zinc in the galvanizing process is obviously better than that in the first plating and after welding, and the welding points are also well protected against corrosion. It’s better to use life, usually in 6-7 years.
The above information about the service life of the galvanized welded wire mesh is expected to help everyone. If you have any questions, please feel free to contact us.
