Megaspan® Purlins & Girts

Metroll Megaspan® purlins and girts are a range of performance enhanced Z and C purlins. The profile has been optimised to deliver capacity improvements of more than 20% compared with standard purlins. Metroll Megaspan® purlins and girts are used primarily in the design of sheds, industrial and commercial buildings. Sections are typically used to support roof and wall sheeting in these buildings.

Metroll Megaspan purlins and girts are manufactured from high tensile G450, G500 or G550 galvanised steel, with a minimum of Z350 galvanised coating (350g/m2) conforming to AS1397. 3. Not all styles are available in all branches. Minimum order quantities may apply. Lead times may apply. Contact your Metroll branch for details.

Important Note:
It is important that standard purlins from Metroll or other suppliers ARE NOT substituted for designs utilising information from the Megaspan design manual. As Megaspan is a higher performance section, standard purlins will not deliver the same load capacities and hence may be under-designed and potentially unsafe.
