1×37 Galvanized Steel Strand

Galvanized steel strands, also called galvanized stranded wires, which are twisted together by several galvanized steel wires. Among different steel wire strands, 1 × 3, 1 × 7, 1 × 19 galvanized stranded wire are the most popular. Because they are made by means of wire drawing followed by hot-dipped galvanizing or electrical galvanizing, the surface of the strands has a layer of zinc. Therefore, the strands have extremely excellent nature, such as excellent abrasion resistance, high tensile strength and corrosion resistance.

Applications
Galvanized Steel Strand has a long history of service to the power transmission industry, the pre-engineering building industry, the construction industry, fishing industry, municipalities and cable structures, etc.

  • Power transmission industry: messenger wires, guy wires, core wires, earth wires, telecommunication cables, barrier cable, etc.
  • Construction industry: high-rise and other commercial structures, multi-level parking garages, structure cables, etc.
  • Road and bridge structures: highway and railway viaducts, suspension bridges and cable-stayed bridges, express way fencing, etc.

Precautions

  1. Surface protection: no folding marks, no scratches, no defects such as broken, crushed, and hard to bend.
  2. The surface of galvanized steel strand should keep away from oil, dirt, water and other impurities.
  3. The ribs on strand surface should be consecutive, no crack and spalling phenomena.
