Valente prestressed reinforced concrete piles are made using the prestress technique, which ensures greater mechanical resistance.
Our pile has a trapezoidal shape with four smooth sides and noedges. This finish allows the use of harvesting machinery in vineyards and does not cause wear to the hail nets in orchard installations. Our trademark is on the front: V for Valente!
Concrete: the concrete used to make Valente piles consists of aggregates (gravel and sand) obtained from screened, calibrated and washed natural materials.
This material gives the concrete a very high strength that is much higher than the aggregates obtained from the crushing of rock. The sand and gravel are mixed with PORTLAND 525 cement which acts as a sealant, keeping them together and giving very high compressive strength.
High carbon low relaxation steel braid structure: a reinforcement is inserted inside the piles to transmit the stress to the product. The steel used is highly resistant (r=1870 N/mm2) and is made of braids that adhere perfectly to the concrete, consisting of two or three intertwined strands with a diameter of 2.25 mm. Specifically:
- Normal iron rod 2 x 2.25 mm strands
- Reinforced iron rod 3 x 2.25 mm strands
The quality of our piles is guaranteed by DNV through the Product Quality Certificate, a document which specifies the maximum and minimum tolerances of posts regarding the following criteria: bending resistance of the finished product; concrete strength; resistance to freezing; straightness of the product.
For aesthetic reasons, piles can be supplied in brown colour: colouring is carried out during mixing, in order to ensure long-lasting durability. Additionally, it is possible to drill holes in the posts up to a maximum of three, where the first hole is at least 10cm from the top of the post.
