Shipping tubes and tubes. Hard paper tubes to be used for the most diverse purpose have been produced at Rositz for 25 years now. It all began with spiral-wound core tubes for the wire and fine-sheet metal industry. In the course of the following years we developed this line of business further. Shipping tubes, rings, shelf tubes, display tubes and construction tubes completed the product portfolio. Production facilities were also expanded to include parallel-wound heavy-duty tubes. Since 2003, as well as conventional tubes with cylindrical cross-section, we have also been marketing square and rectangular tubes. For the transport and storage of sensitive goods we manufacture edge protectors and flat profiles.
