Prestressed concrete poles are commonly mass produced and are used in most countries for power transmission, antenna masts etc. The main advantages of prestressed concrete poles are the following :
(a) Resistance to freeze-thaw effects in cold climate,
(b) Resistance to corrosion in moist conditions and to erosion in desert areas,
(c) Easy handling and transportation due to less self weight,
(d) Fire resistance,
(e) Easy installation,
(f) Clean and neat appearance, and (g) Increased crack resistance and improved rigidity.
