Hot-DIP Galvanized Steel Pole
Hot-dip galvanized distribution poles offer many advantages over traditional wood poles. Among them are increased strength and reliability, reduced installation costs, and life-cycle cost savings. Galvanized poles can also be re-used at the end of their service life, reducing environmental impact.
Galvanized steel poles are manufactured by applying a layer of zinc over the surface of a steel pole. This provides a tough barrier coating and slows the rate at which corrosion occurs. Galvanized poles can be applied to rails, fencing, telephone wiring, and equipment boxes. Galvanized steel is also used for commercial and residential construction. It is also used in high-temperature applications up to 392 degF.
Galvanized steel poles can be used for distribution and transmission power lines. This type of pole provides reliable protection against rust and corrosion. Galvanized poles are also lighter than wood poles, making them easier to transport on rough terrain. They are also much stronger than wood poles, and can support longer spans.
In addition to the benefits mentioned above, hot-dip galvanized distribution poles are also more sustainable. Galvanized steel and zinc can be recycled after the pole's service life ends. This makes hot-dip galvanized poles infinitely recyclable. Moreover, they are more environmentally friendly because they produce zero emissions when used.
While steel poles are more expensive than wood poles under 50 feet, they can save 10 to 20 percent in life-cycle costs. Hot-dip galvanized poles are often made as embedded poles, which reduces installation costs. Also, they can be transported without requiring a special permit. These advantages make hot-dip galvanized distribution poles a good alternative to pentachlorophenol-treated wood poles.
Hot-dip galvanizing is the process of applying a thin coating of zinc over the surface of steel. When the zinc corrodes, the surface of the steel turns to zinc hydroxide and zinc carbonate. When used at temperatures above 392 degF, the zinc-carbonate layer will peel off and expose the steel to further corrosion. As a result, the cross-section area of the pole can decrease, causing tensile failures.
For a pole to last for 75 years or longer, it must be galvanized. This process, performed by hot-dip galvanizing, produces a tough barrier coating that prevents corrosion. It is a good alternative to traditional wood poles, which require regular treatment. When used in conjunction with an advanced coating, hot-dip galvanized poles can last as long as wood poles. The coating provides an effective non-leaching corrosion barrier, and can extend the life of the pole by 2.5 times.
For distribution and transmission power lines, a galvanized steel pole can provide reliable protection from corrosion. In addition, it can be installed in less time and without requiring re-tightening of hardware. It is also 30 percent lighter than wood poles, making it easier to transport and maneuver. In addition, hot-dip galvanizing has no maintenance requirements for 75 years or more.
Several electric utilities are using hot-dip galvanized steel poles to replace traditional wood poles. In the United States, approximately 600 utility companies use steel distribution poles, and the number is growing rapidly.
