Lightweight purlin systems make building construction fast and easy, allowing you to build the envelope and exterior wall and roof structures with little effort.
Ruukki has a wide selection of purlins, which are suitable for both insulated and uninsulated roofs and walls. You can choose an alternative that best suits your needs, depending on the required span length and the loads. The benefits of using purlins are:
The lightweight purlin design is always project-specific. Use our design tool PurCalc

C purlins can be used either as wall purlins or wall posts.
The Z section is excellently suited for a roof purlin. In pitched roofs, it provides optimum load bearing capacity against the weight of structures and snow.
Sigma purlins can be used on longer spans, or, for instance, in sigma frameworks which are used in large-span buildings to achieve moderate spans.
Termo purlins have a higher thermal transmittance (thermal bridges eliminated by up to 90%) and acoustic parameters than other purlins.
