C purlins, also known as Cee purlins, are in the shape of the letter C and provide structural support for beams required for walls and flooring. In addition to roofing, C purlins are often used for structural support in walls and as floor joists.
Z purlin resemble the shape of a letter "Z" and are also referred to as Zee or Zed purlins. They are roof framing members that span parallel to the building eave and support the roof decking or sheeting. The metal purlins are in turn supported by rafters or walls.
Zed purlins are secondary steel framing members used for both roof and wall. Zee Purlins are commonly chosen for the ability to end lap.
