C profile purlin

C profile purlin

Our pre-punched purlins are quick to install and suitable for both insulated and uninsulated roofs and walls. 

The thickness and height of the purlin selected depend on span length and loads. To optimise the design, use our software.

Applications:

  • Industrial construction
  • Hall and warehouse construction
  • Extension construction and renovation
  • Agricultural projects

Our PurCalc software is constantly improved and updated to easily design and optimise Ruukki’s lightweight purlin sections. 
 
Choosing the right filters will help you to select the right product characteristics. The software enables the calculation of various roof purlin systems, whether the purlins are restrained by trapezoidal sheeting or roof sandwich panels. 
 

Installation

Services

Purlins can be pre-punched in our factory. This makes construction on-site faster and easier. The standardised sizes and locations of holes for fixing screws are presented below. Please contact us for additional information about the pre-punching possibilities.

Holes are made during production at continuous line – information:

  • max. material thickness 3mm (for ø 60mm max. material thickness 2mm),
  • holes can be made in a row,
  • oval and rectangular holes can be rotated by 90°.
