Load-bearing sheet T200 – 75L-840

Load-bearing sheet T200 – 75L-840

Load-bearing sheets are suitable for roof decking, external roof sheeting and intermediate flooring, and they can also be used as formwork for concrete slabs. For the most economical design, use Ruukki’s Poimu roof-dimensioning software.

Protection against corrosion

 

 Environment Coating
Inside buildings in environments with corrosivity category C1, C2 according to EN ISO 12944-2 standard and A1, A2 according to EN 10169 standard Steel sheets with zinc coating of 100 g/m2 and with polyester coating SP 15, thickness 15 μm
Interior applications in environments with corrosivity category C1, C2, C3 according to EN ISO 12944-2 standard and A1, A2, A3 according to EN 10169 standard Steel sheets with zinc coating of 275 g/m2 and with polyester coating SP 25, thickness 25 μm

Corrosivity categories according to EN ISO 12944-2 standard, examples

Corrosivity category C1:

  • Interior – heated building with clean atmospheres, e.g. offices, shops, schools, hotels

Corrosivity category C2:

  • Interior – unheated buildings where condensation may occur, e.g. depots, sports halls

Corrosivity category C3:

  • Interior – production rooms with high humidity and some air pollution, e.g. food-processing plants, laundries, breweries, dairies
  • Exterior- urban and industrial atmospheres, moderate sulfur dioxide pollution. Coastal areas with low salinity.

Corrosivity category C4:

  • Exterior -industrial areas and coastal areas with moderate salinity.

Corrosivity categories according to EN 10169 standard (condensation), examples

Corrosivity category A1:

  • Interior – office buildings, schools, residential (except kitchens and bathrooms), dry storage buildings

Corrosivity category A2:

  • Interior – sports halls, cinemas, theatres, cold stores, supermarkets

Corrosivity category A3:

  • Interior – kitchens and bathrooms, food processing (e.g. bakeries), industrial buildings with dry process

Design tools

Dimensioning software Poimu

 

Ruukki offers excellent dimensioning software Poimu, which enables to optimize product choice according to the Eurocode.

 

Just by defining some basic input data you can select a load-bearing sheet for your needs from Ruukki´s selection. This quick optimization tool covers 1-, 2-span and continuous structures and gives the exact solution of sheet that should be used, as well as its length.

Installation

Note! When delivered, the narrow flange of the load-bearing roofing sheet faces upwards in the package, so check if the sheet needs to be turned to be installed correctly.

  • For insulated roofing structures, the load-bearing sheet needs to be turned, as it is installed with the narrow flange against the support. An exception is the anti-condensation coated sheet, which is delivered with the wide flange facing upwards, when semi-warm roof is in question.
  • For uninsulated roofs, the sheet is installed as delivered, with the wide flange against the support.

Safety

Ensuring the health and safety of workers is our priority. We have developed the perfect tools for Ruukki load-bearing sheet site actions. The lifting tool is for lifting load-bearing sheets safely, the safety anchor is for working safely on the roof. The tools are CE-marked and can be used only with Ruukki´s load-bearing sheets.

We recommend using our health and safety equipment when handling and installing load-bearing sheets.

National restrictions might be in place. Please check local usage possibilities from us

Services & options

Web perforation

Standard perforation grade (within perforation area) is 15%. Diameter of perforation holes is 3 mm which are spaced on the basis of equilateral triangle, side equals 7.4 mm.

Due to web perforation of load-bearing trapezoidal sheets, decrease of strength parameters takes place.

In order to determine load capacity of perforated profiles, you are recommended to use Poimu software, which enables dimensioning and optimization of trapezoidal sheets within structure.

 

Acoustics

When you need reduction for reverberation time, please ask for further information from our sales. Our load-bearing profile sheets are tested with different kinds of roof build-ups to meet your needs. We are not limited to only sound absorption, our experts are also ready to consult you regarding the roof sound insulation.  

 

Anti-condensation

When building cold storage or car shelters, please remember that condensation might be harmful. To avoid this, we can provide our load-bearing sheets with anti-condensation layers.
