Steel to plastic conversion

In addition to the conventional systems for steel strapping, FROMM has developed equipment for polyester strapping. This new type of strapping is flexible, absorbing shock impact during shipping, loading and unloading more effectively than steel strapping. The range is divided in pneumatic, manual and electric tools. Electric tools allow an independent working range, ideal for applications requesting not only flexible handling of the tool but also high tension of the strap.
