Stramit purlins and girts are made of high-tensile steel and are primarily used to support roof or wall sheeting in industrial, rural and commercial buildings. While commonly attached to fabricated steel frames, the C and Z sections can also be used in small and medium sized buildings for the structural frame.
Continuously lapped Z purlins generally provide the greatest economy for medium and large buildings. C purlins are often favoured for their stability in single spans and are also adaptable to doubly symmetric “I” and “box” configurations.
The Stramit Exacta C and Z purlins and girts are manufactured from hi-tensile Galvaspan steel and can be coated in a range of options including ZAM coating technology.
Stramit purlins and girts have a Z350 zinc coating and are available in an extensive range of sizes. Accessories like brackets and bolts are also available.
To guide users through installation, Stramit has created a four part video series.
