What are Cee Purlins?

In steel construction, the term purlin typically refers to roof framing members that span parallel to the building eave and support the roof decking or sheeting. The steel purlins are in turn supported by rafters or walls.

Cee Purlins For Metal Roofing

Designed to reduce the distance the rafters have to span, metal purlins support the loads from the roof deck and help to prevent the roof from sagging. Western States Metal Roofing offers two types of galvanized purlins:

C Purlin - Cee or C purlins are shaped like a squared-off letter C. They are often used for structural support in walls and as floor joists in addition to roofs.

Z Purlin - The zee or Z purlin is shaped like a letter Z. Its shape allows the purlin to overlap with others at the joints. This gives zed purlins the potential to be much stronger than C purlins. Z Purlins are mainly used in walls or for large roofing projects.

This adds longitudinal support and provides lateral bracing for compression flanges, increasing the overall frame capacity.

  Cee Profiles are used as both purlins and girts. When used as purlins, the cee-profile is laid horizontally along the length of the roof, providing support to the cladding. As a girt, the cee-profile provides stability and attachment points for wall panels. The structural shape provides strength while the thin gauge of the steel minimizes load on the building frame.

The small profile of a cee-purlin makes it ideal when the width of the structural component is important, for example, when close to eaves.. The center of gravity is in the center of the shape making cee-purlins easier to work with as they balance on their short side without assistance. They are the preferred shape for carports and simple structures.
