Corrosivity categories according to EN ISO 129442 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. foodprocessing 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
Installation
Note! When delivered, the narrow flange of the loadbearing roofing sheet faces upwards in the package, so check if thesheet needs to be turned to be installed correctly.

• For insulated roofing structures, the loadbearing sheet needs to be turned, as it is installed with the narrow flangeagainst the support. An exception is the anticondensation coated sheet, which is delivered with the wide flange facingupwards, when semiwarm roof is in question.
• For uninsulated roofs, the sheet is installed as delivered, with the wide flange against the support.
Services & options
Web perforation
Standard perforation grade (withinperforation area) is 15%. Diameter ofperforation holes is 3 mm which arespaced on the basis of equilateral triangle,side equals 7.4 mm.
Due to web perforation of loadbearingtrapezoidal sheets, decrease of strengthparameters takes place.
In order to determine load capacity ofperforated profiles, you are recommendedto use Poimu software, which enablesdimensioning and optimization oftrapezoidal sheets within structure.
Acoustics
When you need reduction for reverberation time, please ask for further information from our sales. Our loadbearing profilesheets are tested with different kinds of roof buildups to meet your needs. We are not limited to only sound absorption, ourexperts are also ready to consult you regarding the roof sound insulation.
Anticondensation
When building cold storage or car shelters, please remember that condensation might be harmful. To avoid this, we canprovide our loadbearing sheets with anticondensation layers.
