Application
Messenger Wire, Overhead Ground or Static Wire, Guy Wire
Galvanized steel strand wire can be used as ground wire of overhead line, but also can be used as structural cable, supporting cable, cable, block cable and cable reinforcement core. It is made of wire twisted together. There are mainly ASTM standards, BS standards, IEC standards and other production standards. It is widely used in energy, construction, bridge, water conservancy and geotechnical engineering.
Standard
ASTM A-475 , CSA G12-92 , BS183
Construction
Concentrically stranded
Common, High Strength and Extra High Strength
