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.
Applications:
- Office construction

Design tools

ComSlab software for designing composite slabs
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.
