Strong and lightweight our z purlins span upwards of 25 feet depending on the roof load and how spaced out the z purlins are.
The flexible shape of these beams facilitates various designs solutions.
In this section you ll find sample calculations for determining wind and snow loads as well as z purlin and z girt weight tables.
Purlins support the loads from the roof deck or sheathing and are supported by the principal rafters and or the building walls steel beams etc.
They sit between the roofing sheets and the building acting as a support for the sheet to ensure it is firmly attached and safely in place.
