In the past few years, prestressed concrete poles have become a valuable source to replace traditional poles made of steel, reinforced concrete, and timber. The earliest prestressed concrete poles are designed back in 1933 by Freyssinet, a French engineer. After his development, poles start coming in different shapes across sections of prestressed concrete poles available for pole type.
Types of prestressed concrete poles:
A concrete pole machine manufacturer says that a base must consist of the maximum cross-sectional area since it requires ultimate resistance moments. For instance, rectangular shapes are great for smaller lengths, like up to 40 ft. They are offered for the facilitation of prestressed wires at required depths, and also, the transportation gets convenient of such poles.
Other than this, Virendeel poles are also cast-off for smaller lengths, but they are designed of thin foundations that comprise larger bare areas, making them vulnerable to corrosion failure. In contrast, circular poles are the on-the-go for longer length poles; it includes hollow poles that are lighter in weight and possess equal strengths in all directions.
Top 8 advantages of prestressed concrete poles:
- They are designed with quality and properties that made them lighter in weight and more comfortable to handle.
- The installation of these poles is simple in drilled holes.
- In deserted areas, they turn out to be the best resistant to erosion.
- Not only this, they are best at offering reliance for scorching and cold temperatures.
- They are manufactured in various shapes to perform different functions on several aspects.
- The shapes of concrete poles are based on clean and neat finishing to make them look good in appearance.
- The concrete poles have more rigidity and can carry higher loads than poles made of timber and other material.
They are less permeable to corrosion and works as the best resistant to it.
