High Tensile Galvanized Steel Wire, Hot Dip Galvanizing

Everbright Industrial offers high tensile engineering wire material for the telecommunication industries where high tensile strength is needed. The high tensile wire is used as core wire in manufacture of reinforcement of overhead Aluminum Conductors, and making overhead steel conductors. Major wire sizes: 1.9mm, 2.68mm, 3.20mm and 3.60mm for export.
