Z & C Purlins
Z and C purlins carry the roof and wall sheets on a steel building. We supply and fix purlins sized to the span and the sheeting used.
Purlins are the horizontal members that carry roofing and wall sheets on a steel building. Z and C sections are cold-formed, light and strong, and are the standard choice for modern sheds and PEB buildings.
We supply and fix Z and C purlins sized to the span and sheeting, with the cleats, sag rods and bracing that keep them straight and stable.

Common questions
What is the difference between Z and C purlins?
C purlins are used for simple single spans. Z purlins can overlap at supports to make continuous spans, which is useful in longer buildings.
Can you supply only?
Yes. We can supply purlins only or supply and fix them.
Can old purlins be replaced?
Yes, during re-roofing we replace damaged or rusted purlins.
