Product Description

Automatic Interchangeable Steel Frame CZ Purlin Roll Forming Machine

Discover the unparalleled strength and quality of our Heavy-Duty C Z Purlin Machine. Featuring a robust 48mm roll station frame, it is engineered with precision using a 10mm steel plate welding bottom structure and a 30mm steel plate for the bottom table. Our CNC machine processes the surface to perfection. The inclusion of a pre-cutting system allows automatic cutting of the coil once the order is complete, offering significant material savings.
 

Our advanced system includes 7 Units of Automatic Change, enabling seamless interchange between C&Z purlins, along with adjustable feeder width and height for ultimate flexibility:

Advantages:
1. PLC CONTROL for size adjustments ensures easy access and simplicity. This feature minimizes labor costs and allows the production of different sized purlins without the need for manual roller or spacer changes.

2. FORMING WITH PRE-STRENGTHENING guarantees the perfect shape every time.

3. An INFINITE SIZE CUTTER that allows size changes with just a few spins.

4. EASY OPERATION and LOW MAINTENANCE COSTS make this machine user-friendly and economical.

5. The PRE-CUT SYSTEM saves material effectively.

6. Effortless C/Z INTERCHANGE with a single button press.
