Stramit’s Australian-made purlins and girts offer a range of solutions for industrial, commercial and rural buildings.
Stramit's range of Purlins and Girts in C & Z profiles will match existing or new project specification, and come in a range of traditional sizes as well as coating options to suit corrosivity requirements.
While most commonly attached to fabricated steel frames, C and Z sections can also be used as the structural frame in small and medium sized buildings.
All Stramit Purlins and Girts are proudly Australian Made, roll formed at sites across the country to support building projects in every community.
What’s the difference between C and Z Purlins?
C sections are ideally suited to single, non-continuous span construction. C purlins are often favoured for their stability in single spans and are also adaptable to doubly symmetric “I” and “box” configurations.
Z sections can be used for single spans and in unlapped and lapped continuous span construction. Continuously lapped Z purlins generally provide the greatest economy for medium and large buildings.

What materials are Stramit® Purlins and Girts available in?
Stramit C&Z Purlins and Girts are manufactured from hi-tensile GALVASPAN® steel, with a minimum Z350 galvanised coating (350g/m2) or ZAM® coated steel conforming to AS1397.
High tensile steel offers high strength, with low weight.
