Utility Poles That Are Built to Last


If you’re searching for electrical power pole suppliers or, more specifically, wood utility pole suppliers, then look no further. Peak Substation Services strives for excellence as an electrical power pole supplier. We understand that successful developments require superior materials. That’s why our goal is to be one of the best wood utility pole suppliers in the U.S. So if you’re looking for quality wood poles to complete your project or serve as a temporary solution while you wait for steel poles, take a look at the great selection of utility poles we offer. Our Southern Yellow Pine poles, Douglas Fir poles, and Dense Wood Crossarms can be shipped to your location at the time you need them delivered.

Southern Yellow Pine poles are another great utility pole option. We always keep stock of these poles in sizes ranging from 20” to 75” and classes 1 to 9. For projects that require longer lengths, our treating plants are capable of accommodating custom orders. All of our Southern Yellow Pine poles are manufactured according to current ANSI 05.1 standards and come fully treated. Preservative options include CCA, CCA Emulsion, and Planta. Southern Yellow Pine poles are heavy-duty and built to last.


Our Douglas Fir poles are a smart and green-friendly pole option. Their knot-free consistency and sturdy composition make them ideal for both utility and electric projects alike. Choose from our selection of ANSI, CSA and REA approved Douglas Fir transmission and distribution poles. We carry lengths from 20” to 130”. Douglas Fir poles are lightweight due to their softwood nature and are considered some of the safest poles on the market.


Our dense wood crossarms are a cost-effective, long-lasting option for electrical utility projects. They come in either Douglas Fir or Southern Pine timbers. To protect the integrity of our quality crossarms, CCA or Pentachlorophenol preservation treatments are available. Our crossarms are available in 8” and 10” sizes (standard utility length.) Custom lengths are also available within the 4-28” range. Available thickness: 3.5” X 4.5”, 3.75” X 4.75”, and 4.25” X 5.25”. We can also accommodate custom sizes up to 8” thick and 18” wide.

There are different types of utility poles. They are usually made of wood, concrete, or metal—but can also be made of fiberglass or other composite materials. Larger poles made of metal or concrete are typically used to support high voltage transmission lines, whereas wooden poles are made to aid in the transport of power to consumers via distribution lines.

The majority of utility poles currently in use are made of wood. These wooden utility poles are pressure-treated for protection against the elements and insects. The most widely used type of wooden utility pole is made from Southern Yellow Pine, which we sell (in addition to Douglas Fir). 

ANSI, ASTM, and AWPA (American Wood Protection Association) have set test criteria and wood preservation processes and standards for wood preservative materials. In years past, creosote was used to preserve utility poles. Today, pentachlorophenol, copper naphthenate, and borates are used instead as they are more environmentally friendly. 

Utility poles in the U.S. are a standard of 40 feet in length with 6 of those feet being buried in the ground for a foundation. Although, some poles can be as high as 120 feet, if needed. In general, poles are spaced apart by about 300 feet in rural areas and by about 125 feet in urban areas. These distances can, of course, vary depending on the application and environment. The standards for construction and maintenance of utility poles and their equipment is set by the National Electrical Safety Code, published by the Institute of Electrical and Electronics Engineers (IEEE). 

Utility poles or transmission poles are used to support overhead power lines and transformers. The lines are not only placed overhead to keep them out of the way of people and vehicles: More importantly, they’re placed there to insulate them from the ground.
