C Purlins - Galvanized

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.
