For more than 30 years, utilities have turned to Valmont for steel tapered transmission poles and H-frames. We pioneered fabrication and finishing processes known throughout the industry for quality and reliability. Tapered tubular steel poles continue to dominate other construction options in the utility industry for a variety of reasons:
Flexibility
Steel poles can be designed and fabricated to any height and strength, while still being shipped in easy to handle sections. This enables the customer reduce costs by designing a line for the optimum structure spacing. Steel structures are also easily modified in the field, making them easy to rework.
Ease of Installation
When compared to lattice structures, the speed and ease of installation of steel poles is a proven winner. Also, the behavior of a steel pole is easily predicted, while a lattice structure, with its hundreds of bolted joints, is difficult to quantify precisely.
Uniformity
Constant taper without twists, knots, splits or bows provides uniform diameters every time. Steel also has uniform material strength throughout the entire structure providing more consistent and predictable results than wood. Being an inherently ductile material, steel tends to bend rather than break, resulting in structural reliability and reducing the chance of catastrophic failure in the field.
Maintenance
After installing steel poles, there's no need to retighten hardware later due to pole shrinkage. Steel retains its shape and strength and isn't susceptible to damage by woodpeckers, insects, rot or fires.
Corrosion Protection
A variety of finishes are available with steel, including galvanized, paint over galvanized (powder coat or liquid), dulled and darkened galvanizing and weathering steel. Below-grade coatings are available for direct embedded poles.
