2 - 4mm Thickness Culvert Sheet Metal Roll Forming Machine With Track Cutting


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.

1. Large capacity

One single-silo capacity is up to 17,000 tons with comprehensive configurations to meet customers’ different requirements.


2. High accuracy

Complete advanced processing equipment and technology are introduced from USA to effectively ensure working accuracy and reduce damage to galvanized layer.


3. Less residues


External installable stiffeners contribute to less grain residues on silo walls.

4. Detachable and movable

With standardized and modularized production, components and parts have a high standardization and good interchangeability, thus can be partially replaced or completely transferred.
