Galfan (high vanadium) cable and the difference between the PE cable

With the continuous emergence of new building forms, exposed to the natural environment of steel or cable structure is growing, so the market needs a high degree of corrosion resistance, to overcome the adverse effects of the external environment on the building, relatively beautiful appearance of the new coating materials, So Galfan coating came into being. Foreign research and development of 95% ZN, 5% AL, mixed rare earth alloy as a new coating of steel corrosion. Its characteristic is superior to the galvanized layer. Corrosion capacity is 2-3 times the ordinary hot-dip galvanizing, it is widely used in steel curtain wall and other fields, to achieve the use of life after the surface of green gray.


PE cable (HDPE) using high-density high-density polyethylene material, with excellent anti-corrosion properties. Generally use parallel wire or stranded wire PE cable, mainly for the bridge or steel curtain wall. This process needs to be coiled in the factory after the disk, and then the use of large-scale transport equipment will be transported into the cable tray to the construction site.


For the two cable, the advantages and disadvantages. High vanadium cable production process relative to the PE cable is simple, but the appearance of anti-corrosion life is slightly lower than the PE cable, PE cable production is slightly more complex, especially the need to install the cable clip PE cable sometimes need to peel, such as surface water treatment shall not cause Internal oxidation, transport cable around the need to protect the package to prevent human damage. PE will reach the service life after the surface will crack aging.


Based on the above characteristics, the user can choose the application based on the actual site conditions!
