Steel Spiral Silo Roll Forming Machine Profiled Silo Wall Panel Rolling Equipment

Product description:

The cold roll forming line is specially offered for constructing spiral steel silo. The steel coil is decoiled to deliver the steel plate to the forming machine. Then the steel plate will be processed into the shape required. Subsequently, the bending machine is employed for bending and plate edge processing, to form a spiral strip with the width from 30-40mm. The spiral strip produced by the grain silo forming equipment is used to strengthen the silo structure.

The cold roll forming machine can be applied for bending two kinds of materials for on-site silo construction. The silo roof is assembled on the ground, requiring no scaffold or other auxiliary equipment, The cold roll forming line operated at the speed of 3-5m per minute, resulting in a short construction period.
