Pros and Cons of Different Pole Materials

When it comes to choosing the right material for poles, there are several options to consider, each with its own unique advantages and disadvantages.

In this post, we will compare the pros and cons of steel, timber, concrete and fiberglass poles to help you make an informed decision.

First, there is a range of different pole types and suppliers in each of these categories and some are better than others. We can help you differentiate to find the best one for your network, but the comparisons below are general.

Steel poles are durable and somewhat resistant to weathering, fire, and damage. They are relatively easy to install and relatively flexible in design and construction options. They tend to be higher cost than wood but lower cost than other materials. They are not particularly environmentally friendly, although they are recyclable. They require regular maintenance to prevent corrosion and corrosion can occur anywhere above or below ground and is significantly affected by coastal environments and groundwater, among others. There are minimal NDT inspection options that can detect issues outside the groundline zone.

Timber poles are a natural and renewable material that is easy to work with and relatively inexpensive. They are also flexible in design and construction options. They tend to be the lowest cost-for-strength option. They require regular inspection, maintenance, and treatment to prevent decay and insect attack and extend their lifespan. One benefit is that it is rare that degradation occurs in the below-ground sections that aren't easy to inspect. Many NDT devices have been developed to help with efficient serviceability assessment.

​

Concrete poles are generally durable and resistant to weathering and damage. They are not as easy to install as some others, mainly due to inflexibility in attachment locations and their weight. They tend to be one of the more expensive materials when considering the material, freight, and installation costs. They are not particularly environmentally friendly and are difficult to modify or repair if damaged. NDT inspection methods with any confidence are not available at the time of writing.

Fiberglass poles are durable, and resistant to weathering and damage. They are also lightweight and easy to install, making them a popular choice for applications where weight is a concern. However, fiberglass poles are more expensive than other materials. They also require special techniques and equipment for installation and may not be suitable for all applications. NDT inspection methods are not commercially viable at the time of writing. There are many different types and not all are developed with knowledge of all the demands that will be placed on them over the 60+ year life expectancy.

Overall, the choice of pole material depends on the specific requirements of the project and the type of application it will be used for. Steel, timber, concrete, and fiberglass poles all have their own unique advantages and disadvantages, and it is important to carefully consider the pros and cons of each material before making a decision.
