Lashing wire

Aerial lashing wire acts as a support structure for other types of wire, making it an essential element in many wiring applications. Often, technicians will use a specialized machine — a lasher — to form these critical connections.

Cable lashing wire, in conjunction with a lasher, can facilitate easier installations, drive lower hardware costs, reduce maintenance requirements for a cable setup and increase the overall lifespan. 

Bekaert offers a range of lashing wire grades with varying specifications to suit your project needs. Understanding our available options can help you find the right product for your cabling applications. Our team is prepared to assist you if you need guidance for your lashing electric wire.

Each selection of lashing wire meets ASTM A580 specifications. We provide three grades of stainless steel lashing wire — Type 430, Type 316 and Type 302. Both Type 430 and Type 316 have a 0.045-inch diameter. Type 302 lashing wire comes in two diameters — 0.045 inches and 0.038 inches.

Type 430 (S43000) lashing wire is a low-carbon stainless steel wire with 17% chromium. Though certain conditions can cause dark surface staining, this alloy's characteristics make it ideal for general use applications. Its tensile strength ranges from 70k to 95k psi, and it has an average break load of 125 pounds. Each coil is 1,200 feet long and weighs 6.5 pounds. 

Type 430 is suitable for ordinary atmospheric exposure. This lashing wire performs best away from industrial applications involving pollutant emissions and in conditions farther than 25 miles from saltwater.

Type 316 (S31600) lashing wire provides the best corrosion resistance in coastal areas. This modified 18-10 stainless steel alloy contains 2.5% molybdenum. Type 316 boasts good corrosion resistance against most chemicals, including sulfides and chlorides. In other grades, salt spray causes pinhole corrosion and pitting. Type 316 stainless resists these reactions.

Type 316 has a tensile strength ranging from 95k to 125k psi, and its average break load is 145 pounds. Each 1,200-foot coil weighs 6.5 pounds. 

Annealing is a heat treatment method that alters the mechanical properties of metals. The annealing process has three steps — recovery, recrystallization and grain growth. During this process, controlled heating and cooling relieves internal stresses and encourages the growth of new grains without pre-existing flaws. Once the annealing process is complete, the metal has uniform grains and a range of beneficial properties.

Processes such as bending, drawing and cold forming can lead to work hardening that makes metals more challenging to work with and susceptible to cracking. Annealing reverses the effects of work hardening to make metal products more workable and precise.

Some advantages of controlled annealing are:

• Reduced hardness and increased ductility for better formability.
• Minimized brittleness for reduced risk of failure.
• Improved machinability from lower hardness. 
• Elimination of mechanical complications like cracking from residual stresses. 

At Bekaert, we consider multiple factors when determining the price of our lashing wire. Some of these factors include:

• Wire diameter
• Steel grade
• Coil length

Our goal is to create lasting products at competitive prices. While we have to consider material usage and labor in our product development, we can work with you to identify the best option for your budget.
