Spiral duct flanger

This product has been discontinued and removed from our shelves.

Due to the particularity of spiral duct, the beaded part of the lock-seam is as thick as three layers of steel sheet. In the traditional way, the flanging strip can be flanged only after being processed, and the working efficiency is relatively low. The hydraulic spiral duct flanger newly developed by SBKJ can realize direct flanging without any processing, which is labor-saving and highly efficient.
