The 1500/1500C spiral duct forming machine is used to turn galvanized sheets, stainless steel, and aluminum into a spiral pattern, and further forming it into round ducts. These two models are exceptionally economical and designed to meet basic duct production needs, making them ideal for startup manufacturing plants.

The production diameter for both tube formers range between 80 to 1500mm, while the SBTF-1500C works on material with a thickness larger than 2mm.
