Technical details

Several families of steel floors are available to be used for different applications in order to meet specific requirements:

Cofraplus® floor decks: trapezoidal steel sheets with open ribs and specific embossment to ensure the composite action with concrete. Thanks to their geometry, they are stackable for easy storage, the sheets can be pre-punched to pass the shear connectors of composite beams. Cofraplus is the best solution for most uses involving spans up to 4.5 m.

Cofrastra® profiles: thanks to their undercut geometry, an especially high adhesion between the steel and the concrete can be achieved. A further advantage of this range of composite floor decks  is the quick and easy installation of technical equipment beneath the slab thanks to an adapted fixing system. Without noisy drilling, the system is suitable for any kind of highly technical equipped buildings (e.g. hospitals) that require a certain flexibility for easy changes in the technical installations during their service life.

Cofradal® integrated floor system: made of steel, thermal insulation, reinforcement and concrete. Two to three times lighter than conventional concrete floors, it provides a high load capacity and bridges long spans economically without additional support.

Cofraplus® 220 additive steel deck: easy installation at high speed and outstanding resistance at reduced weight are the main features of this new system particularly suited to all column-beam structure projects without intermediary joists.

Floor Systems in Steel

ArcelorMittal's range of floor construction systems is the most comprehensive on the market and consists of both well-established systems and innovative solutions which reflect recent developments in regulation, design and installation.

Floor systems serve as a self-supporting formwork, they resist construction loads and concrete weight. They are simple and quick to lay. Easy cutting and quick interlocking of the ribs contributes to site productivity.

The laying of floor systems creates a continuous working platform that allows site workers to walk over several complete levels of the construction straight away. The floor can be safely walked on once it is fixed to the supports.

Floor systems are made up of galvanised decks or galvanised-pre-coated decks. These profiles, carefully combined with materials such as concrete, thermal- and acoustic insulation, plaster and wood, form advanced construction systems intended for all types of structures where their effectiveness and reliability is proven.
