What Types of Structures Use Guy Wires?

There are many applications for guy wires. The strength, size and coating required for guy wires depend on their application and location. For example, guy wires used to support heavier towers must have additional strength compared to guy wires for supporting lightweight tents. Additionally, opposing forces will dictate the wire's strength. For instance, heavy winds increase the force on a tower or pole, which requires stronger guy wires or more wires to ensure long-term support. 

Below, you'll find various types of structures that use guy wires.

Guy wires are commonly used to support utility poles for telephone, cable, and power lines. Utility poles are buried in the ground and can stand on their own before being connected to utility lines. Once connected, the lines create pulling forces on the poles, requiring additional support to keep them upright. This is why utility poles, especially dead-end poles, are often referred to as "guyed poles."

In populated areas, there’s a concern that guy wires may become electrified. To protect the public, insulators are placed near the top of the wires to prevent electricity from traveling along the strands. Reflective covers are also added near the anchor points to improve visibility and reduce the risk of accidents.

Exceptionally tall light towers may need guy wires to prevent them from swinging due to high winds or the weight of the lights on top. While not all light towers need guy wires, local codes may require extra support for structures over 10 feet tall. In certain cases, guy strands may not be a requirement but offer benefits for the light tower, such as securing the tower to ensure a safe work environment.

While guy wires may not be required for installing light towers, they can provide necessary stabilization and support, especially in locations with high winds.

Using guy wires has enabled television and radio antennas to become some of the tallest structures in the world. In fact, one of the world’s tallest structures for decades was the KVLY-TV antenna in North Dakota. This guyed mast, built in 1963, measured 2,063 feet tall. Currently, it remains the second-tallest broadcasting mast. This tower has guy wires to support it through heavy winds and inclement weather.

Note that taller antennas have advantages over shorter alternatives. These towers can send out signals to a wider area, increasing the broadcasting range for radio or television stations. In rural areas, such broadcasting can increase the number of people connected to local news. As a result, guy wires play a crucial role in ensuring people have access to news, entertainment and more.

The guy strands used for broadcasting antennas need to support the structure and avoid interfering with radio or television signals. As with cell towers, antennas may need insulation to prevent problems with the signals sent from the tower.

Flare stacks can experience vortex shedding problems when wind causes vibrational forces to add stress to the structure. While flare stacks can stand on their own in calmer conditions, using guy wires can enhance their stability in the wind and mitigate the impact of vortex shedding. When choosing support for flare stacks, consider the additional ground space required for anchoring the guy strands needed for stability.

Many tents used for outdoor events need stability to stay upright and protect the people inside of them from the elements. For large tents used for outdoor catered events, both pole and frame styles use guy wires for support. These guy wires ensure proper tension of the covering and a way to keep the tent upright during high winds. Companies that rent such structures rely on using strong guy lines to keep their large tents secured from collapse or blowing away in heavy wind conditions.

Some trees may also benefit from using guy wires. For instance, newly planted trees usually require extra support because the top of the tree may be heavier than the roots can hold. When a young tree needs support and has a diameter of four inches or wider, guy wires may be a solution. Depending on their application and the spacing of trees in the area, guy wires may stretch from a tree to the ground or go between two or more trees.

Those who frequently plant young trees along often use guy wires instead of staking to keep trees stable until their roots grow properly to support the tree. Additionally, arborists implement guy strands to support damaged trees until the plant can heal itself and use its natural support system.

For decades, Bekaert has manufactured steel wires for multiple industrial and commercial applications. Among the types of wires we produce are guy wires for the power and communications industries. How does our expertise make a difference in our products?

First, we heavily invest in research and development. This prioritization leads to innovations such as our zinc-aluminum alloy coating, Bezinal®. This coating differs from the industry standard of galvanized zinc coating by providing better protection against the elements. It's one of the ways our R&D investment ultimately benefits our customers, giving them a connection to truly unique products.

Second, we put quality control first in our manufacturing processes. Bekaert products are made in America and use quality steel and coatings requested by the customer. For applications such as telecommunications towers, the type of coating and wires make a difference in performance. Since guy wires require customization, we work hard to ensure that our customers' requests are met.

Third, our line includes galvanized guy wires with Class A, Class B or Class C zinc coatings. These classes correlate to the amount of coating in weight per square inch. Class A has the lowest weight per square inch of galvanized zinc coating while Class C has the highest. 

Another corrosion-resistant option we provide is our proprietary Bezinal®, which is a zinc and aluminum alloy that doesn't fit into galvanized zinc classes. In fact, Bezinal® provides even greater resistance to corrosion than standard galvanized zinc. Our rigorous testing process ensures that all of our galvanized zinc or Bezinal®-coated guy wires will stand up to the harshest elements.

Fourth, we strive to offer exceptional customer support. From expert advice, design flexibility and fast turnarounds, we can meet the strictest requirements for steel guy strands.
