Product Description

Z Purlins or Zed Purlin (Support Rails) are horizontal beams that help to form the roof and wall joists of a building shell structure. They usually 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.

They are designed to sit between the flashing and the roof sheet, to help avoid the flashing leg flapping in the wind, if the leg doesn’t reach the next available profile upstand on the roofing sheet. They should be stitched into the roofing sheet valley (the flat part) and then the flashing leg will stitch into the mini zed. Most commonly used in agricultural and industrial buildings, due to their extremely versatile and lightweight properties (which also make them easily adapted for use in a variety of different sized buildings).

Available in 3m lengths only and perfectly designed to suit your selected profile (each profile has different profile heights so these support rails can only be used for the 32/1000 box profile and 34/1000 box profile sheeting). The available sizes are 50mm x profile height x 50mm; so for our 32/1000 profile it is 50mm x 32mm x 50mm and for our 34/1000 profile the size is 50mm x 34mm x 50mm.

Supplied in your choice of finish and colour. Choose from Galvanised Steel, Plastisol or Polyester leather-grain effect. They come manufactured in a 0.7mm thickness and in 3m (3000mm) lengths.

  • 0.7mm thickness (gauge);
  • 3000mm (3m) length;
  • Choice of colour and finish;
  • 50mm x profile height x 50mm;
  • Welted edge for added strength;
  • Suitable with our 32/1000 or 34/1000 box profile sheeting.

These flashings are sold in 3m lengths and are 0.7mm thick. Always wear appropriate eye and hand protection, and only use tools and accessories for their intended purposes.
