The INCO 70.4 composite profile is used as a composite steel deck, together with concrete, to form floor slab structures in industrial buildings, administrative buildings, residential constructions, and other types of buildings. It offers excellent performance within composite slab solutions, with an effective width of 840 mm, a rib height of 70 mm, and a rib spacing of 210 mm.

The perforations in the composite profile allow the passage of cylindrical connectors (Nelson type) previously welded to the beams.

The composite profile performs a dual function: it acts as permanent formwork during the concrete pouring phase, achieving spans of up to 4 m without the need for temporary propping, and as positive reinforcement in the composite phase, ensuring that the slab can reach spans of up to 5 m. It is especially designed to provide slab systems with a minimum total depth of 120 mm, including a 70 mm rib height and a 50 mm concrete topping.
