Technical details

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 are proven.

ArcelorMittal’s family of flooring solutions includes:

Cofraplus® floor decks: Trapezoidal steel sheets with open ribs and specific embossment to ensure composite action with concrete. Thanks to their geometry, they are stackable for easy storage. Cofraplus® is the best solution for most projects 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. Technical equipment can be installed quickly and easily beneath the slab thanks to an adapted fixing system.

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, which is particularly suited to all column-beam structure projects without intermediary joists.
