Composite sheet CS48-36-750

Ruukki’s Composite profile CS48-36-750 is intended to be used as reinforcement in concrete slabs. During casting the sheet works as formwork, Steelcomp can be used as a ceiling surface beneath the slab due to its aesthetic design; and therefore, a suspended ceiling is not necessary needed.

    Design tools
    To make both architectural and structural design work easier, with accurate product information in 3D form, we offers a selection of CAD / BIM -objects and software tools, to be downloaded from the Software Toolbox portal.

    Dimensioning software ComSlab

    The software is meant to be used as a design tool for Ruukki´s SteelComp composite slabs. The complete capacity verification for a composite slab can be done, including also design for fire exposure. The user can optimise the construction during the design and select the cost-optimal composite slab for each application.
