4. Product description
Strength, durability and cost efficiency in roof constructions
Load-bearing profile sheets are the optimal choice in different roof constructions due to their weight and load-bearing capacity
The most economical solutions can be obtained by using Ruukki’s Poimu- dimensioning software for roof optimization
Load-bearing profiles are suitable for roof decking, external roof sheeting and intermediate flooring
They can also be used as formwork for concrete slabs 4

11. Application in buildings
Ruukki load-bearing profiles can be used for insulated and uninsulated roofs for example in the following buildings:
production halls
warehouses
shopping centers
office buildings
sports buildings
renovation projects 11

12. Application in buildings
An example of a project where insulation comes over the load bearing profiles

14. Technical information
Web-perforated profiles
Perforation grade: 15% (3mm, c/c 7.4 mm)
Improvement in sound absorption
Improvement in reverberation time 14

15. Technical information – anti condensation
Anti-condensation is used to remove the possibility for water to condensate into the lower surface of the profile
Anti-condensation absorbs and prevents water drops to emerge
Usually used in cold storages and halls
Factory installed

16. Technical information – supporting beam structures
HEA -Beam
IPE-beam
Welded I-Beam
Truss
Concrete
Reinforced concrete
Laminated timber
In addition to above structures, it is also possible to use different types of purlins as a supporting structure, for example Z-purlins and sigma-purlins

17. Technical information – fasteners
Fasteners for supporting beams
Fasteners for the edge beam, and for the overlapping

18. Technical information – fastening the profiles to the supporters
Profiles are fastened from the middle of the smooth part of the flange
The sizes, types and quantities of the fasteners are defined by designer
The minimum distances between the edge of the profile and the fastener are marked on the enclosed picture
b = the width of the ”flat flange”
The absolute minimum edge distance for the fastener is 25 mm

21. Technical information – Fastening of the supporting sheet
Sometimes, if the supporting structure is too narrow, it is possible to use a supporting sheet to “widen” the supporter
The principle is demonstrated in the enclosed pictures

22. Technical information – sideways overlapping
Normal
One wave overlapping
Double sheet
It is possible to increase the load bearing capacity by adding extra overlappings
Must be calculated by Poimu – software

23. Technical information – sideways overlapping, uninsulated water roof
If there was an insulation to come, it would be impossible to put the fasteners on top of the profile (It would break the vapour barrier)
This kind of fastening is used when the profile acts as a water roof

24. Calculation – Poimu software
With Ruukki’s Poimu software you can calculate and optimise load-bearing sheets needed for the project.
With the software you can choose the best load-bearing sheet type, thickness and static scheme quickly and efficiently.
Poimu optimisation tool covers one, double-span and continuous structures
Apart from internal use, the software is made available for external use. Customers can download it from a Ruukki’s software platform

Safety at work
Back to contents page 27

28. Safety at work
Always wear protective clothing – especially safety gloves while working with profiles
Be aware of the sharp edges of the profiles
Don’t go under the load while profiles are being moved
Ensure that the lifting belts are suitable for lifting (inspected in time) or use the lifting tool provided by Ruukki
Try to avoid handling the profiles during heavy winds
While moving on the roof, follow great caution and use certified safety rope (lifeline), safety anchor and safety boots with soft sole
Always pay attention to the local safety regulations

29. Safety at work – safety anchor
The safety anchor device SA , attached to the load-bearing profiled sheet, is according to directive 89/689/EEC (CE-marked)
Safety anchor SA is a safety device for working on roofs, which was designed and tested by Ruukki
The device is only compatible with load-bearing profiled sheets manufactured by Ruukki, within the limits specified in the safety anchor’s usage instructions

30. Safety at work – lifting tool
The lifting tool is according to directive 2006/42/EY (CE-marked)
It is meant to used in lifting Ruukki’s load bearing profiles
It is possible to lift the profiles one at a time, or several together
The bundles must be separated from each other by bedding timbers, height of minimum 70 mm, to be able to use the lifting tool
The lifting tool is composed of two different main parts and of the lifting belt that combines them
