GSW Stay Wire Guy Wire Standard Galvanized Steel Wire Strand BS183 1972 Standard

Galvanized steel wire also names GSW Wire, Messenger Wire, Overhead Ground or Stay Wire, Guy Wire, GI Wire. Galvanized Steel Wire Strand, Galvanized steel strands, galvanized stranded wires, and GSW wires, which are twisted together by several galvanized steel wires.

Applications

Galvanized steel strand wires can be used as ground wire of overhead line, supporting cable, cable, block cable and cable reinforcement core. GSW widely used in energy, construction, bridge, water conservancy and geotechnical engineering,also used for overhead ground/shield wire, guys and messengers, and for steel core in ACSR conductors.

Construction

1. The single wires are concentrically stranded and wrapped helically around a central wire.

2. Zinc-coated grade of steel strand wire /guy wire: Class A ,Class B and class C.

Concentrically stranded Galvanized steel wire strand available in class “A”, “B” and “C” galvanizing, “A” being the least heavy and “C” being the most heavy.

Feature

Environmental protection zinc coating.Thick and firm zinc coating.Good corrosion resistance of Class A.Unique anti-rust process on joints.Toughness maintains a long time.Good stability and reliability.

Standard

ASTM A475, ASTM A363, IEC 61089 BS183:1972 and Other International Standard.

Specification

BS 183: 1972 Specification for general purpose galvanized steel wire strand.
