Concrete poles type Spinazzè

Concrete poles from FruitSecurity Holland are the Spinazzè concrete poles. An important feature of the Spinazzè concrete piles is the inside, made of harmonious steel, braided strands. These strands are prestressed. That is why the names span concrete or prestressed concrete are also used. Thanks to the inner steel strands, the concrete poles can bend with great elasticity and withstand large forces.

The prestressed concrete posts are periodically tested in extreme conditions to verify their resistance before being installed in orchards or vineyards. Technical information with the most recent test results is available at request.

Concrete poles for covering

Prestressed concrete poles are used as support poles in pear and apple orchards. However, Spinazzè concrete posts are also widely used as concrete posts in covering structures. Covering such as hail nets in pear and apple orchards. Concrete poles also serve as the structure's backbone in film canopies for cherries, raspberries, redcurrants and apricots. The Powerflex Foil System is therefore often installed using Spinazzè concrete poles. More and more often, we see the concrete post in the fencing of meadows, but also in orchards and yards.

Strong concrete poles

The unique thing about Spinazzè concrete poles are the ingredients. The raw materials come from the Piave River. The gravel and sand have unique properties that form a good basis for the poles. The cement that is used is a secret family recipe that makes the strength of the poles unparalleled. The strength of the concrete poles depends on the number of wires in the concrete post. These threads are prestressed. These threads provide the flexibility in the concrete post. Extra wires that are pulled can add a lot of strength to the post. This can be up to 30 percent more force.

Sizes of concrete poles

The various sizes of the poles are there to be used for a specific purpose.
