Galvanized Steel Wire Strand for cable,messenger ,guy wire,stay wire
1. Application
The galvanized steel wire strand is used for overhead ground lines or electrical power transmission lines. Stay or guy wire strands are produced for use with poles, towers, or any other form of guying.
Galvanized steel wire strand refers to any steel wire product that has subjected to a galvanizing process to improve its resistance to corrosion. This process typically involves dipping the finished wire product into a bath of heated zinc compound to form a scratch and corrosion resistant coating across the entire surface of the wire. Galvanized steel wire strand in multi-core electrical cables. Its low cost and ease of production makes galvanized steel wire ideal for mass produced corrosion resistant wire products. It is an indispensable industrial, agricultural, and DIY fastening and reinforcement standard.
