Solutions and Products
Prestressed Reinforced Concrete piles are made using pre-tensioning technique, which ensures a greater mechanical resistance.
Valente pile has a trapezoidal shape with four smooth sides and no edges, so to allow use of harvesting machines in vineyards. Our trademark is on the front: V for Valente!
Valente pre-stressed cement piles are realized with the wise combination of two fundamental components: concrete and steel braids.
Concrete used for cement posts consists of aggregate materials (gravel and sand) obtained from screened, calibrated and washed natural materials.
These materials give to concrete a very high strength, far higher than aggregates obtained from crushed rock. Sand and gravel are mixed with PORTLAND 525 cement which acts as a glue, keeping them together and giving very high compressive strength.
- High carbon content steel braid with low relaxation
Inside cement pile a steel reinforcing braid assures pre-stressing to the product. Used steel is highly resistant (r=1870 N/mm2) and made of braids that perfectly adhere to concrete, consisting of two or three intertwined wires with a diameter of 2.25 mm. Specifically:
- Normal braid 2 x 2.25 mm wires;
- Reinforced braid 3 x 2.25 mm wires.
Piles quality are guaranteed by DNV through Product Quality Certificate, a document which specifies maximum and minimum tolerances of posts according to following parameters:
- bending resistance;
- concrete strength;
- resistance to freezing;
- product straightness.
For aesthetic reasons, piles can be supplied in brown color: color is added directly to the mixture, in order to ensure a long-lasting durability. It is also possible to drill up to three holes in the posts, where first hole should be at least 10cm from pile top.
