Purlin Roofing Systems
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. Metal for 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 zed 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.
It is used widely as purlin and wall beam on steel structure construction. Also it can be combined into a light weight roof truss, brackets, etc. In machinery light manufacturing, C purlin can also be made into Column, beam or arm limb, etc.
Purlins constitute the most important aspect when it comes to any kind of structural support system in a building. It's a horizontal beam used for structural support, most commonly applied beneath roofs. They attain support from the rafters and building walls. Purlin manufacturers most commonly produce three types of purlins, namely, Z and C purlins and rectangular hollow section purlin.
