Galvanized steel strand ASTM A 475 BS 183 for Guy wire Stay Wirealvanized steel strand A
Features
1. The galvanized stranded wire offers low rotation.
2. It has flexible construction.
3. It offers excellent spooling.
4. The galvanized stranded wire is recommended for high lift.
Application
We offer 1*19 galvanized stranded wire, which is extensively used as overhead ground wire or static wires. These stranded steel wires are made under various national and international standards and are used in overhead transmission lines, guying wires of poles, earth wires of overhead transmission, etc.
We are an experienced 1*19 galvanized stranded wire manufacturer based in China. Apart from galvanized stranded wire, we offer 15.24mm prestressed concrete strand wire, 17.80mm PC strand, 1.6mm, 2.0mm and 2.64mm galvanized steel wire, and much more.
