Expert tip: The key to a firm structure is the even spacing of purlins throughout your metal building structure.

  • Once you have noted the installation details, it’s time to trim or cut the purlins to the required measurement.
  • The next step is to attach your purlins with trusses or rafters securely. This can be done by employing nuts, bolts, and screws or wielding them at your preparation site. 
  • After fastening your Z or C purlins, lay down your plywood or decking material on your structure’s roof.
  • Once you have installed your deck (roofing) material, you can add other roof materials like shingles and tiles as per your requirements.
