Messenger Wire Manufacturer and Supplier

Our telecom wire, including steel messenger wire, meets the strict specifications set by ASTM International, a global leader in establishing material standards to ensure consistent performance. These standards outline the ideal characteristics and testing methods for various materials, including steel messenger wire.

Our specifications include ASTM 475, which covers metallic-coated steel wire strands, and ASTM A228 (music wire) for optical cables. We also offer customized specifications upon request to meet specific needs.

Messenger wire is used exclusively in telecommunications, typically for aerial fiber optic cable installations on telephone poles. It prevents sagging from the cable's weight, extending its lifespan.

Messenger strands are not suitable for ground wire applications, as they aren't designed to carry electrical current. Ground wire requires specialized materials, and messenger wire is not typically used with short cables where extra support isn't needed.

Using Messenger Wire With Aerial Messenger Cable

Messenger strand structurally supports aerial fiber optic cables in above-ground installations. To provide this rigidity, the cables must be tethered with lashing wire. The lashing process involves spiral wrapping the messenger wire and fiber optic cable using a lasher machine.

Lashing the messenger wire and fiber optic cable offers these benefits:

• Holds the cables in place
• Reduces stress on the cable and its fibers
• Enhances the life span of the cables
• Decreases hardware costs
• Simplifies the installation process
• Reduces maintenance requirements for cable setup

Bekaert offers stainless steel lashing wire coils in three grades, all meeting ASTM A580 specifications. We sell this product in bulk sizes of six coils per box for convenient ordering.

Even the strongest steel wires are vulnerable to degradation. Corrosion is the leading cause of messenger cable deterioration and breakage. To prevent damage, Bekaert offers various coating options for your steel messenger strand. When you work with Bekaert for messenger wire, you can be confident in the durability of the finished product.

Galvanized-Zinc Coatings 

Quality coatings enable our drop cable wires to perform well in harsh conditions and provide the necessary support for telecom cables. Galvanized zinc-coated wires have excellent corrosion resistance. We offer messenger wire with three classes of galvanized zinc coatings, including:

• Class A: Class A zinc galvanized wire has the thinnest coating weight of all three classes and is ideal in less corrosive environments. 
• Class B: Class B wire has double the weight of a Class A coating, which makes it more resistant to corrosion.
• Class C: Class C zinc galvanized wire has the heaviest coating of all three at triple times the weight of Class A coating. This coating is well-suited for high-corrosion areas. 

Our Bezinal® Coating 

In addition to our three classes of zinc-coated wires, we offer Bezinal®, a zinc-aluminum alloy coating that provides superior corrosion resistance. Bezinal® outperforms hot-dip and electro-galvanized coatings in various corrosive environments, lasting two to six times longer than other materials. This extended durability reduces repair costs and minimizes the need for cable replacements, saving time and money.

All Bekaert coatings, including non-zinc galvanized options, meet industry standards. Bezinal® meets ASTM A855/856 and ASTM 640 classifications.

Our messenger wires are safer and more reliable due to their standardized strength. The steel cores enhance their durability, making drop cables with Bezinal® coatings ideal for challenging conditions. These wires offer excellent weather resistance, protecting against rust, sagging, or breakage caused by harsh weather, such as high winds and ice loading.
