1*7 Galvanized Stranded Wire
Description
Our galvanized stranded wires provide a combination of superior
properties compared to conventional six strand ropes. With
compacted structure and smooth face, this 1*7 galvanized stranded
wire provides enhanced durability and resistance to abrasion and
crushing, and improves the service life.
Construction & Diameter: 1*7/4.8-12.7 mm
Features
1. The galvanized stranded wire offers a smooth and polished
surface.
2. It offers excellent antirust performance.
3. It is adhesive and flexible.
Application
Our 1*7 galvanized stranded wire can be used as messenger wires,
guy wires, core wires or strength members, earth wires/ground
wires, barrier cables, structure cables, messenger wires for
optical fiber cable, etc.
As a professional 1*7 galvanized stranded wire manufacturer and supplier based in China, We also offers1*3, 1*19 galvanized stranded wire, 12.70mm PC strand, 2.0mm and 2.64mm galvanized steel wire, among others.
