Q.What is galvanized steel wire used for in cables?
A. Galvanized steel wire provides tensile strength and corrosion resistance, making it ideal for overhead power lines, suspension bridges, and animal fencing.
Q.How does galvanization protect steel wire?
A.The zinc coating acts as a sacrificial layer, preventing rust even when exposed to moisture or harsh environments.
Q.What are the common diameters of galvanized steel wire cables?
A.Standard ranges from 1.2mm to 6mm, with thicker wires used for heavy-duty applications like construction nets.
Q. Is galvanized steel wire suitable for marine environments?
A. Yes, but for saltwater exposure, higher zinc coating (e.g., 275g/m²) is recommended to prevent premature corrosion.
Q.Can galvanized steel wire be welded?
A. Yes, but the zinc coating must be removed first to avoid toxic fumes and weak joints.
Q.What’s the difference between electro-galvanized and hot-dipped galvanized wire?
A.Hot-dipped offers thicker zinc layers (better durability), while electro-galvanized provides a smoother finish for finer cables.
Q.Does galvanized wire conduct electricity?
A. Yes, but it’s primarily used as structural support in composite cables, not as the primary conductor.
Q.How long does galvanized steel wire last outdoors?
A.Typically 20-50 years, depending on coating thickness and environmental conditions (e.g., industrial pollution reduces lifespan).
Q. Is galvanized wire recyclable?
A. Absolutely—both steel and zinc are recyclable materials, often reused in new metal products.
