| THE ADVANTAGES.
|
 |
|
|
 NO MAINTENANCE
|
The users prefer the concrete poles owing to the absence of corrosion and maintenance
which are specific of the steel poles.
|
|
|
|
SECURITY
|
 No cracks owing to the use of the prestressing,
thus preventing the corrosion of
steel bars which sometimes occurs in reinforced concrete poles.
No failure: the yield strength is 2,1 times
the nominal strength.
|
|
|
|
FATIGUE RESISTANCE
|
|
The tests show that the prestressed concrete poles
can endure at least twice more alternate
strengths than the reinforced concrete ones,
thanks to the absence of cracks.
|
|
|
|
QUALITY OF THE MATERIALS
|
The prestressing demands the top quality
of the high tensile steel and of the concrete,
which is the best guarantee.
Any wrong material is rejected by the factory.
|
|
|
|
LIGHTNESS
|
|
The prestressing allows to reduce the weight
of the poles by 25 to 30% when compared
to the reinforced concrete ones.
|
|
|
|
CUTTING THE COST
|
Low cost of production:
Domestic manufacturing and use
of the local materials (cement, agregates...)
High cut of steel needs which means savings
of foreign currencies.
No maintenance.
