Are You Using the Right Lashing Wire for the Job?

Stay Informed

Lashing wire is stainless steel wire commonly used in the utility and telecommunications industries to bring and support aerial cables or a combination of cables to a supporting strand. It is produced by a specially controlled annealing process which yields a uniform fine-grain structure throughout wire length and cross section for best results. When selecting a lashing wire, it’s important to consider the application’s weather conditions and other environmental factors to ensure a successful and long-lasting installation.

In this article, we summarize each lashing wire type to help you select the optimal wire for your project needs.

Type 316 Stainless, 1,200’ Coil

Developed specifically for use in coastal regions, Type 316 stainless steel wire is the most resistant to corrosion from most chemicals, including chlorides and sulfides. It is particularly resistant to pitting and pin-hole corrosion commonly associated with the salt and humidity in oceanside atmospheres. Type 316 wire is ideal for use in areas near saltwater or in areas with high levels of industrial pollutants.

It is considered the best choice and go-to-wire for most lashing jobs where corrosive failure and atmospheric conditions are a concern. It contains 10% nickel content and 2.5-3.0% molybdenum.

(Superlash) Type 302 Stainless, 1,600’ Coil and Type 302 Stainless, 1,200’ Coil

Type 302 stainless steel wire comes in two diameter sizes: .045” and .038”. Even at the smaller diameter of .038”, the wire is equal in strength to a .045” Type 430 wire, while providing more flexibility (easier bending and unwinding) and better elongation (less chance of breakage from stress).

It is considered the preferred selection between the Type 430 and the Type 316 stainless steel wire under normal atmospheric conditions. The Type 302 provides a good compromise option between the two, because it offers better corrosion resistance than the Type 430 stainless steel and is not as expensive as the Type 316 stainless steel. The Type 302 contains 18-20% chromium content and a minimum of 8% nickel.

Type 430 Stainless, 1,200’ Coil

Type 430 stainless steel wire is recommended for general use and in ordinary atmospheric conditions. It is not recommended for use within 25 miles of saltwater or industrial operations that emit pollutants. It is low carbon and contains 17% chromium wire content.

Specifications

Now that you understand the general differences between lashing wire types and know which type would best meet your project needs, it’s time to select a supplier. Marathon stainless steel lashing wire is coiled to fit all standard lashers, including the C, J2 and Apollo lasher machines. It is manufactured in lengths of 1,200’ or 1,600’ coils and packaged in cartons of six coils. Other sizes are available upon request.
