GSW Stay Wire Guy Wire Standard Galvanized Steel Wire Strand ASTM A475 Standard
Applications
Galvanized steel wire strands (Stay Wire) are used for sustaining mechanical load. Generally they are made up of 6 wires stranded around 1 wire, twisting 7 wires together. A common use for stay wires is in the electricity industry, using the wire to stay power poles and tower structures.
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
Galvanized Steel Wire, Stay wire, Messenger Wire, Overhead Ground,Static Wire, Guy Wire.
Grade: Utilities, Common, Siemens-Martin, High Strength and Extra High Strength.
Finish Coatings: Class A, B and C and Bezinal, a superior corrosive coating of 5% Aluminum and 95% Zinc.
Standard
ASTM A475, ASTM A363, BS183:1972 and Other International Standard.
Specification
ASTM A363: This specification covers concentric lay stranded steel wire composed of three or seven wires with a Class A coating specifically intended for use as overhead ground/shield wires for transmission lines.
ASTM A475: This specification covers the five grades of class A zinc-coated steel wire strand, Utilities, Common, Siemens-Martin, High-Strength, and Extra High-Strength, suitable for use as guy and messenger wires.
