Galvanized Cee Purlins Zee purline rolling forming machine is designed to make C purline, Z purline in batch fully automatically with punching or without.

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.

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. Here are some drawing profiles for your reference:
