Galvanized Clad steel wire earth wire/stay wire/guy wire/spacer cable (GSW)

Applications
The galvanized steel wire strand is used for overhead ground lines or electrical power transmission lines. Stay wire or guy wire strands are produced for use with poles, towers, or any other form of guying.
Grades
Utilities, Common, Siemens-Martin, High Strength and Extra High Strength. S1A or S1B; S2A or S2B; S3A or S3A.
Finish Coatings
Class A, B and C D E and Bezinal, a superior corrosive coating of 5% Aluminum and 95% Zinc.
