What is a Z shape purlin forming machine?
The Z shape purlin roll forming machine is capable of producing various profiles of Z shape purlins by modifying the rollers.
This machine is fully automatic and user-friendly, featuring an intuitive HMI panel. It includes a decoiler, sheet guiding equipment, a roll forming section, a PLC control system, hydraulic cutting, and a collection table.
The primary advantages include beautifully customized designs, straightforward and stable operation, and a robust body frame.
What is a Z purlin?
Z purlins, also known as zed purlins, are purlins characterized by a Z-shaped cross-section, serving as horizontal beams intended to form the roof and wall joists of a building's shell structure. They are positioned between the roofing sheets and the building, providing support to ensure that the sheets are securely attached and safely positioned.
What is the purpose of Z purlins?
The notable strength of Z purlins lies in their capacity to overlap, creating a stable connection that can withstand greater loads compared to C-shaped purlins. Consequently, they are frequently utilized in the design of roofs, trusses, factories, civil houses, and more.
