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.
