How to choose galvanized or PVC razor wire from QUNKUN METAL?

Razor wire is widely used in many fields all the world. After a series of process, the razor wire will have the function of corrosion and rust prevention. The most common type of razor wire in the market is the galvanized razor wire and PVC coated razor wire.

The chemical property of zinc is more active than iron. Therefore, when electrochemical corrosion occurs, zinc is more active than iron. The oxide of zinc is denser. Therefore, in order to further prevent oxidation, galvanized blades have better corrosion resistance to prevent to get rust. Galvanized razor wire generally refers to hot-dip galvanizing.

 

PVC is a layer of polymer plastic protective film formed on the outer surface of the raw wire of razor wire. Since the razor wire is made after over molding, the cross section of the blade will expose the wire, which will be exposed during actual use. After being washed by rain, the cross-section will corrode, so the service life of the PVC barbed wire will be shortened.
