Cardboard cores
Cardboard tubes can be used for many various applications, for example: winding of foil, electrical cables, carpeting, fabrics, steel, non-ferrous metals, etc. Cardboard tubes can be used as structural elements for manufacturing musical instruments, speaker housings, furniture, and for other applications in various industries.
Dimensions
We can manufacture tubes of following dimensions [mm]:

Parallel design – 290; 300; 378; 392; 475; 500; 550; 600.
In case of tubes with diameters different to specified above, once all details are agreed upon, we can start production with 6 weeks from receiving the order.
Tube design
The tubes are made of appropriate number of cardboard layers glued together in helical or parallel fashion.
Maximum wall thickness of a helical design tube is 15 mm, for tube length of up to 6000 mm. For parallel design tubes the maximum length of is 1150 mm and maximum wall thickness is 25 mm.
