The C and Z purlin machine is an advanced fully automatic roll forming system designed for producing both C-shaped and Z-shaped steel purlins on one production line.
This machine is widely used in steel structure construction, industrial buildings, warehouses, and roofing systems. With an intelligent automatic adjustment system, it allows quick switching between C and Z profiles without changing rollers, greatly improving production efficiency and reducing labor cost.
Compared with traditional single-profile machines, this automatic C/Z interchangeable purlin machine provides higher flexibility, faster operation, and more stable performance, making it an ideal solution for modern steel structure manufacturers.
The C and Z purlin machine is built with a heavy-duty welded steel frame to ensure stability during high-speed production. The main structure is precision-machined to guarantee accurate alignment and long-term durability.
The forming system uses high-quality 45# steel rollers, which are heat-treated and hard chrome plated to improve wear resistance and extend service life. The shafts are finely polished to ensure smooth operation and consistent profile accuracy.
A key feature of this machine is its automatic C/Z switching system, which enables fast profile conversion without manual roller replacement. Operators can switch production modes through the PLC touch screen within minutes.
The machine is equipped with an advanced PLC control system, allowing users to set production length, batch quantity, and profile specifications easily. This ensures intelligent control and high production efficiency.
Hydraulic cutting ensures precise, clean cuts without deformation. The punching system can be customized according to customer requirements, including oval holes, round holes, or slot punching.
This C and Z purlin production line is suitable for processing galvanized steel and cold-rolled steel with thickness ranges from 1.5mm to 3.0mm.
The C and Z purlins produced by this machine are widely used in:
One machine can produce both C and Z purlins, increasing flexibility and reducing equipment cost.
