DESCRIPTION
z purlin dataTRANSCRIPT
Z purlinOur prepunched 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 ourPurCalc software.
Applications:
• Industrial construction
• Hall and warehouse construction
• Extension construction and renovation

Services
Purlins can be prepunched in our factory. This makes construction onsite faster and easier. The standardised sizes andlocations of holes for fixing screws are presented below. Please contact us for additional information about the prepunchingpossibilities.
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°.

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