· ​Superior Galfan (95/5 Zn-Al) Defense: The eutectic 95% zinc and 5% aluminum-mischmetal alloy coating provides up to 3 times the corrosion protection of standard hot-dip galvanizing, actively preventing white rust and red rust in aggressive atmospheres.
· ​Flexible Structural Options (1x7 & 1x19): Available in 1x7 configurations for standard utility guy lines and 1x19 constructions for high-modulus architectural or heavy tower rigging requiring minimal stretch and high stiffness.
· ​High Ultimate Breaking Load: Built from high-carbon steel wire rods, delivering exceptional mechanical safety factors to safely anchor tall telecom structures against extreme cyclic wind loads and seismic forces.
· ​Full Metallurgical Traceability: Manufactured under strict ISO 9001 protocols. Each commercial shipment includes a comprehensive Mill Test Certificate (MTC) verifying tensile strength, breaking load, and alloy coating mass.
​Engineered for heavy-duty structural anchoring across telecommunication and broadcast networks:
· ​Telecommunication & Cellular Towers: Self-supporting and guyed communication masts, cellular base station towers, and repeater stations.
· ​Broadcast & Radar Infrastructure: TV and radio transmission towers, radar station rigging, and weather observation masts.
· ​Coastal & Offshore Utility Anchors: Guy lines and structural support tethers deployed in high-salinity marine air or heavy industrial pollution zones.
​Q: What is the difference between 1x7 and 1x19 Galfan guy wire structures?
A: 1x7 features 7 thicker wires, offering great flexibility and utility-grade strength for standard guy lines. 1x19 features 19 wires, providing a higher metallic cross-sectional area, greater structural stiffness, lower stretch, and a smoother surface profile for specialized tower rigging.
​Q: Why choose Galfan coating over traditional galvanization for telecom towers?
A: Galfan alloy coating offers significantly extended service life (typically 2 to 3 times longer than standard galvanization), drastically reducing costly maintenance and re-tensioning cycles on remote or tall communication towers.
​Q: What is the standard export packaging and transport safety?
A: Coils or wooden reels are securely wrapped in heavy-duty moisture-proof materials, strapped with high-tensile steel, and palletized to prevent any mechanical damage or surface abrasion during international tran
