Product Description

Versatile Automatic Change Steel Frame Roll Forming Machine

Heavy-duty, high-quality C Z Purlin Machine with a 48mm roll station frame. We incorporate a robust 10mm steel plate welding bottom structure and a 30mm steel plate for the bottom table, precisely processed by CNC machines. The pre-cutting system ensures automatic coil cutting upon order completion, optimizing material usage.
 

Featuring a 7-Unit Automatic Change System, this machine facilitates seamless interchange between C&Z purlins, feeder, width, and height adjustments.

Advantages:
1. Effortless size adjustments with PLC control, simplifying the production of various purlin sizes without manual roller or spacer changes, reducing labor costs.

2. Advanced forming with pre-strengthening ensures impeccable shape consistency.

3. An innovative infinite size cutter enables quick size changes with minimal effort.

4. User-friendly operation with low maintenance costs.

5. A pre-cut system that maximizes material savings.

6. Seamless C/Z interchangeability at the push of a button.
