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.
A lighter floor can be made by using polystyrene in-fill blocks and then a floor covering or by creating voids within the floor using corrugated steel sheets or thin concrete slabs over the elements.
The ribs and lower part of the beams are also reinforced with steel mesh. The side profile is wedge shaped with a rough surface to allow the in-situ concrete to be easily applied.
The two ribs give the beam a high torsional rigidity and excellent transversal load distribution. This means that the element is self supporting during the transport and construction phases.
The main applications for these beams are:
They can be used with a prefabricated structure or with an on-site cast structure with joints designed to meet the technical specifications required.
The beams can be manufactured with heights from 500 mm to 1000 mm and with a standard width of 1200 mm or, by using the same machine, in a width of 800 mm simply by changing the internal side formers of the Slipformer.
