Galvanized Steel Strand
Zinc-coated steel strands provide mechanical support strength for overhead line and guy wire applications.
GSW – Galvanized Steel Wire Strand
Galvanized steel wire strand for guying, messenger and mechanical support applications.
GSW is selected where high tensile strength and galvanized surface protection are required for support, guy, messenger or overhead infrastructure routes.
Product Overview
GSW is a galvanized steel wire strand used mainly for mechanical support rather than power conduction. It is commonly reviewed for guying, messenger and overhead support applications where strand grade, breaking strength and galvanizing requirements control product selection.
Applications
- guy wire and stay wire applications
- messenger strand for overhead infrastructure
- support strand for utility and communication routes
- mechanical reinforcement or tensioning applications where specified
Construction
Concentric stranded galvanized steel wires. Final diameter, strand construction, steel grade, galvanizing class and minimum breaking strength should follow the required standard.
Standards
- ASTM A475
- BS 183
- project-specific galvanized steel strand requirements
Main Features
Support and Messenger Use
Suitable for stay wire, guy strand, messenger and mechanical support routes where conductivity is not the main function.
Strength-Class Review
For GSW - Galvanized Steel Wire Strand, nominal diameter, strand construction, zinc coating and minimum breaking load should match the required standard.
Comparison Table
| Product / Route | Main Use | Selection Guidance |
| GSW | Galvanized mechanical support | Guy, stay and messenger applications. |
| ACS | Aluminum-clad steel strand | Support or shield applications requiring aluminum-clad surface. |
| CCS | Copper-clad steel strand | Grounding or bonding support routes requiring copper surface conductivity. |
Product Selection Guide
Standard & Size Route
Confirm whether the project uses IEC, ASTM, BS, DIN, GB, AS or NFC conductor tables before selecting size.
Electrical Requirement
Compare nominal area, DC resistance and current requirement against the line design and utility specification.
Mechanical Loading
Check rated strength, span length, sag requirement and wind/ice conditions before confirming conductor family.
Alternative Conductors
For higher tension or corrosion performance, compare AAC, AAAC, ACSR, ACAR, AACSR or ACSR/AW as applicable.
