U Panels

U Panels are prestressed concrete elements that have a constant cross section.

They are manufactured using high tensile strength prestressed strands, wires or single wire which are embedded within the element.

The production of these elements is achieved using our Slipformer machine that casts elements continuously on a long production bed without the need of any formwork.

U Panels were developed to surpass the height and weight limits of traditional precast floors. It is the result of detailed market analysis to drive forward technical solutions and the implementation of advanced engineering being applied to Nordimpianti’s casting machines.


Field Applications

The TopFLOOR and TopBRIDGE series floor elements are suitable for use in any structure where it is necessary to cover large spans with self supporting beams.

The product finds its natural applications in the field of infrastructure (such as roofs, rockfall guards, underpasses and bridges) although it can also be effectively used for industrial and commercial structures.

Top Floor

Top Floor N / Top Floor S
The lower part of the slab and the vertical ribs are vibrated in one operation by NORDIMPIANTI’s Slipformer Machine. Within of the lower part and the ribs there are the pre-stressed wires and steel mesh for the vertical and horizontal load distribution.

The N series is characterized by a U profile and by the concrete topping being cast at the construction site. Steel mesh protrudes from the top of the element in order to have a good key with the cast topping.

Polystyrene (EPS) blocks can be put within the U of the element and the on-site topping can have steel mesh to help withstand the loading.The product in this version is very light making it very economic to handle and transport. The thickness of the lower part of the element can be adjusted if an increase in loading or fire resistance is required.

N version TopFLOOR elements come in standard heights of 53, 63, 73, 83, 93 mm. Every element is completed at the construction site with a concrete topping.

The S series has a box profile with the concrete topping cast directly at the element production site. After steel mesh is placed over the Polystyrene (EPS) the concrete topping is cast with another special slipformer machine.

This floor can be completed with either a concrete topping cast at the construction site or casting concrete between the sides of the element. This last solution gives side continuity from one slab and another.
The thickness of the concrete topping as well as the lower part of the element can be adjusted depending on customer’s needs.

S version TopFLOOR elements come in standard heights of 60, 70, 80, 90, 100 mm but they can also be customized.

Top Bridge

Top Bridge N / Top Bridge S
The Top Bridge series is characterized by having substantially larger sections able to accommodate a greater quantity of reinforcement to comply with category 1 Bridge regulations.

Otherwise the manufacture is the same as that for TopFLOOR.
