Galvanized Strand

Combine the strength of high carbon steel wire with the excellent corrosion resistance of Class A, ASTM B6 High Grade, hot-dip zinc coating. Add a long history of service to the transmission industry, the pre-engineered building industry, the construction industry, and municipalities and you get strand that you can count on year after year.

  • Meets or exceeds ASTM Specifications A475 or ASTM A363
  • Excellent corrosion resistance

Typical applications:

  • Overhead ground wire strand for power transmission lines
  • Messenger strand for telephone and CATV lines
  • Guy strand for power distribution poles, telephone poles and microwave and radio towers
  • Wind bracing in pre-engineered buildings
  • Barrier cable and guard rail strand
  • Other guying applications where small size, high strength and corrosion resistance are necessary

Our Galvanized Steel Strand meets or exceeds ASTM Specifications A475 or ASTM A363. Each manufacturing run tests the following:

  • Minimum Breaking Force (see chart)
  • Ultimate Elongation (High Strength 5%--Extra High Strength and Utilities Grade 4%)
  • Individual wire tolerances
  • Wire Coating weight—ASTM Method A90
  • Wire wrap test for coating adherence
  • Wire wrap test for steel ductility
  • Preforming check
