Discover our wooden line poles

Located in Boisset-les-Montrond (42), France Bois Imprégnés is the leading producer of wooden utility poles for electricity and telecommunications in France. Combining expertise in traditional craftsmanship with the use of cutting-edge technologies, we offer wooden poles that embody both strength and environmental responsibility. Our commitment to sustainability and quality enables us to meet the most demanding needs in the electricity, telecommunications, and public infrastructure sectors.

Our wooden line poles are designed to withstand the harshest weather conditions and support heavy loads. Made from fir, spruce, Douglas fir, and pine—species renowned for their mechanical strength—our poles are treated to ensure durability while maintaining an attractive aesthetic. The most commonly used lengths in the telecommunications sector range from 6.25 m to 10 m, but we also offer lengths from 8 m to 15 m, along with various strength classes to meet all requirements.

Treatments and wood species

The treatment process for wooden poles follows a rigorous protocol. It begins with perforation (for better impregnation in risk zones), performed before drying to prepare the wood. Next, the poles are placed in dryers, a crucial step to reduce their moisture content and minimize the risk of deformation. Simultaneously, a thermal treatment is applied.

To ensure optimal protection against biological attacks and demanding weather conditions, we carry out a Class 4 autoclave treatment (perforation zone) under vacuum. This treatment provides maximum defense against moisture, fungi, and insects while offering an attractive finish: green by default or brown upon request.

Technical specifications

Our wooden line poles are manufactured in compliance with the NF EN 14229 standard, ensuring high levels of quality and safety. Each pole undergoes mechanical planning and specific perforation tailored to species such as fir and spruce. This perforation system optimizes the penetration of treatment agents. Additionally, our rigorous factory production control, certified under conformity number 0380 – CPR – 5803, ensures that every pole meets the strictest quality requirements.

Achievements and references

With our expertise, we are the preferred choice of renowned companies such as ERDF, RTE, as well as those in the fiber optic sector and the export market. These partners are among our regular clients. We also collaborate with numerous companies specializing in the installation of overhead lines, who appreciate the quality and strength of our wooden poles. Our continuous presence in the market for many years is a testament to the trust our know-how inspires and the performance of our products.

Usage and Maintenance Tips

The durability and effectiveness of our poles depend not only on their intrinsic qualities but also on how they are installed. Here are the installation recommendations to ensure optimal longevity:

Plumbness: Ensure the pole is perfectly upright, with a tolerance of ±10 cm at the top of the pole.
Lateral Support at the Base: Use draining materials and place the first key stones around the pole at the bottom of the hole to ensure stable support.
Backfilling: Use calibrated natural gravel and compact in layers to enhance stability.
Additional Support: Install three key stones in total, paying special attention to the first and last, as they are critical to ensuring the long-term stability of the pole.

By following these recommendations, you will ensure a robust and durable installation of your wooden poles.

FAQ: We Illuminate your questions

Why choose wooden utility poles over metal or concrete poles?

Wooden poles offer an eco-friendly and flexible solution while providing excellent mechanical strength and long-lasting durability. Unlike metal or concrete, wood is naturally an excellent electrical insulator.At higher altitudes, wood is particularly recommended due to its ability to absorb shock waves caused by extreme weather conditions, making it ideal for such demanding environments.

What is the price of a wooden utility pole?

Our wooden poles, available in lengths ranging from 5.50 to 8 meters with a diameter of 1 meter at the base varying depending on the class, are suitable for a wide range of projects. Prices range from €35 excluding VAT to €115 excluding VAT per unit, departing from the factory, providing excellent value for money.
Additionally, delivery is available, allowing you to receive your poles directly at your site as needed

What type of wood is used for telephone poles?

The types of wood we prioritize for our pole production are primarily conifers such as fir, spruce, and Douglas fir due to their excellent technical and mechanical properties. We particularly select wood from high-altitude regions, known for its robustness and resistance to harsh weather conditions, ensuring a longer lifespan for our poles.
It’s worth noting that the only wood species we do not use is Weymouth pine, as its characteristics do not meet our performance and durability requirements.

What is the lifespan of wooden utility poles?

Wooden poles typically have an average service life of 40 to 50 years, providing optimal performance during this period. We also guarantee a performance of 10 years, based on the usage conditions specified in our recommendations.
