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
- Public construction
- Industrial construction
- Warehouse construction
- Renovation construction

Design tools

Poimu software for dimensioning load-bearing sheets
Dimensioning software, Poimu, allows you to optimise product choice according to the Eurocode. Simply by defining some basic input data you can select a load-bearing sheet for their needs from Ruukki's selection. This quick optimisation tool covers 1-, 2-span and continuous structures and gives the exact solution as to what sheet should be used, as well as its length.

Anticondensation layer
Profiles with anti-condensation layer are protected against water condensation directly at the bottom surface of the metal sheet. The layer absorbs water which then may be evaporated into the surrounding environment during a change in weather conditions.
Perlite coat, sprayed only on the bottom surface (back coating side) of the profile.
Layer weight | 400 …. 1 000 g/m2 |
Water-absorption capacity | ~0.5–0.8 l/m2–1.1–1.5 l/m2 |
Coating method | Sprayed |
Colour | Light gray |
Diluting agent | Water |
Composition | Perlite grains, cellulose fibres, water and binder |
