Spiral Folding Principles

AGICO steel silo uses the most advanced spiral undercutting technology in the world. While being constructed, coil sheet of 495 mm in width is shaped through the shaping machine, bent by the bending machine, and then undercut to form a spiral protruding strip of 30-40mm width around the silo body, which plays a role of strengthening the silo body. Our shaping machine is also able to fold two different steel sheets together at the same time.
