Z120-300 Z Purlin Machine
The Z purlin machine is a type of continuous roll forming equipment designed to produce Z purlins of various sizes according to specific requirements. Both web width and flange height can be adjusted manually or automatically. With full automation, the machine allows for size switching between 120mm and 300mm in just one minute via PLC control.
Z purlins play a crucial role in supporting roofing materials like steel structures by distributing the roof’s weight to the main structural framework of the building. Typically used in conjunction with other building components such as roofing and walls, Z purlins provide a stable framework for securely connecting these materials.
