Lightweight purlins

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:

Light weight
High-strength properties increase efficiency
Efficient logistics
Good corrosion resistance
Can be used also in demanding conditions
Fully recyclable

The lightweight purlin design is always project-specific. Use our design tool PurCalc
to optimize the wall or roof structure.

	C purlin C-sections Height: 100, 120, 150, 200, 250, 300, 350 mm Thickness: 1.0–3.0 mm Minimum length 1600 mm Maximum length 18500 mm	C purlins can be used either as wall purlins or wall posts.
	Z purlin Z-sections Height: 100, 120, 150, 200, 250, 300, 350 mm Thickness: 1.0–3.0 mm Minimum length 1600 mm Maximum length 18500 mm	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 purlin Sigma sections Height: 150, 200, 250, 300, 350, 400 mm Thickness: 1.5–3.0 mm Minimum length 1600 mm Maximum length 15000 mm	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.
	H purlin H-sections Height: 100, 125, 150, 200, 250 mm Thickness: 1.0–2.5 mm Minimum length 1600 mm Maximum length 15000 mm	H purlins are used as roof purlins, wall purlins or, for example, as truss chords. H purlin has a very high lateral stiffness.
	Termo purlin C, U and Z-sections Height: 100, 125, 150, 175, 200, 225, 250, 300 mm Thickness: 1.0, 1.2, 1.5, 2.0 mm Minimum length 1600 mm Maximum length 15000 mm	Termo purlins have a higher thermal transmittance (thermal bridges eliminated by up to 90%) and acoustic parameters than other purlins.
