Working Process

The process includes: decoiler → leveling / uncoiling → guiding → roll forming (multi-step) → hydraulic shear → output / stacking.    The PLC system automatically measures and cuts each piece to the preset length.    Users only need to feed the coil and collect the finished sheets.

Highlights / Advantages

• Stable frame reduces vibration & deformation

• Precision forming ensures high-quality trapezoidal profile

• Automatic cutting eliminates manual measurement error

• High speed improves production efficiency

• Simple operation with touch screen interface

• Low maintenance and long service life

• Flexible configuration and easy expansion

• Safe design with emergency stops and protection devices

About After‑sales & Support

We offer 24-month warranty, free wear parts, lifetime technical support, and optional on-site installation or remote commissioning.    If buyer requires, we can provide application drawings, profile design, and user training.
