Main Applications of Sigma Purlin Roll Forming Machines
A Purlin Roll Forming Machine serves many applications in industrial construction. The most common use is manufacturing purlins for roofing and wall support systems.
In roofing structures, purlins are installed parallel to each other beneath roof panels. They provide a stable foundation for metal roofing sheets and help the building withstand external forces. Different profiles, such as C and Z purlins, can meet various load-bearing requirements.
For wall cladding systems, purlins create a strong supporting framework for exterior panels. They help maintain the alignment of wall materials and improve the overall rigidity of the building envelope.
Furthermore, roll formed purlins are widely used in steel workshops, agricultural buildings, storage facilities, and large-span structures. Manufacturers can also produce customized purlins for mezzanine floors, building extensions, and special construction projects.
