Automated Reversible Stacking Line For Asymmetric G Shape Purlins

Automated Reversible Stacking System for Asymmetric G-Shape Purlins

These introductions refer only to the production line and configuration shown in the main image. Each machine is custom-built. Metalign welcomes your inquiry and provides the right production line—forming metal into profiles aligned to your needs.

1. Production Line Overview

• This stacking solution targets cold-formed steel producers serving light steel construction, prefabricated buildings, and structural steel suppliers, offering reliable, automated post-processing with strong adaptability for asymmetrical profiles.

2. Production Process

• Purlin Flipping → Magnetic Gripper → Robotic Stacking Arm
• The line flips each G-shape purlin 180° for alternating orientation, uses magnetic gripping for secure pickup, and stacks precisely via robotic arm—ensuring compact and stable piling, perfect for downstream packaging or shipment.

3. Technical Parameters

4. Key Focus

• Designed for asymmetrical G-shape purlins with alternating stack orientation.

• Robotic arm enables high stacking precision and flexibility.

• Magnetic gripping ensures safe, damage-free handling of steel profiles.

• Reduces labor cost and increases automation level at end of line.

• Ideal for export-ready packaging with minimal space usage.
