  • Purlins are horizontal beams that are used for structural support in buildings. Most commonly, purlins are major components of roof structures.
  • Zed purlins are galvanised steel beams which are usually used on larger scale jobs and primarily used on roofs. The zed purlins we sell are commonly used on industrial and agricultural buildings. With the 'Z' shape they are made in they are able to overlap in to one another allowing a stronger structure than a cee section. The zed purlin allows the roof sheet to be fixed securely and safely as it goes between the building and the roofing sheet.
  • Our 140mm zed series come in lengths of 4.572m(15ft), 6.096m(20ft) and 8.000m(26ft3') and are all in a 1.6mm thickness.
  • The 4.572m & 6.096m lengths are pre-punched, while the 8.000m is unpunched.
  • These are used in co-junction with cleats to help fit the purlin to the building, Southern Sheeting supply these

  • What are purlins used for?
     A purlin is used for structural support in buildings and fitted to the structure which enables roof and cladding sheets to be fixed to them.

  • What is the maximum spacing for purlins?
    A roof purlin should be spaced at no greater distance than 1.8m for 0.7mm box profile sheeting. There are many factors that can affect this, and this is just a rough idea to use.

  • How are the purlins attached to the building?
    A purlin is connected to the framework of the building by a cleat that is bolted or welded to the column or rafter.

  • Where do I use a Z purlin and a C section purlin?
    Z purlins are commonly used in roof applications, while C sections are used to support walls or floors of the building. However, Z purlins can also be used for the walls as well.

  • Which is stronger, a Z or C purlin?
    The z purlin is stronger due to its shape, hence why it is used for the roof application.
