· ​Superior Galfan (95/5 Zn-Al) Defense: The Eutectic 95% zinc and 5% aluminum alloy coating provides up to 3 times the corrosion resistance of standard hot-dip galvanization, actively inhibiting white and red rust in marine or industrial atmospheres.
· ​Enhanced Coating Ductility & Adhesion: The alloy microstructure offers exceptional bendability and impact resistance, ensuring the protective barrier remains completely intact during winding, pulling, and pole-line hardware installation.
· ​High-Modulus Span & Sag Control: Built from high-carbon steel wire rods, delivering minimal structural elongation and superior stability to support heavy bundle-wrapped fiber optic cables across long pole spans.
· ​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 suspension and support systems across modern telecommunication and broadband networks:
· ​Fiber Optic & FTTH Networks: Aerial ADSS/Figure-8 fiber optic cable suspension, drop wire support, and long-span rural broadband installations.
· ​Coastal & Marine Telecommunications: Coastal telecommunication lines, island-connecting overhead cables, and port infrastructure networks exposed to salt spray.
· ​Harsh Industrial Atmospheres: Communication and signal messenger wires running through chemical plants, railway corridors, and high-pollution urban zones.
​Q: Why choose 95/5 Zn-Al (Galfan) coated messenger wire over traditional galvanized wire?
A: Galfan coating offers significantly higher corrosion resistance (typically 2 to 3 times longer lifespan) due to the dense aluminum-rich oxide layer, making it the ideal choice for high-corrosion coastal or industrial fiber projects where maintenance access is difficult.
​Q: Do these Galfan messenger cables comply with international standards?
A: Yes. Our 95% zinc 5% aluminum coated strands are produced and tested in strict accordance with recognized specifications such as ASTM A855 and EN 10244, ensuring seamless acceptance by major telecom operators.
​Q: What is the standard export packaging and transport safety?
A: Coils are securely wound on robust wooden reels or packed in durable weatherproof pails, wrapped in heavy-duty moisture-proof materials to prevent any mechanical abrasion or damage during international transit.
