The grooved tube is characterised by its external as well as internal flower-shaped section: it differs therefore from the lined tube, whose internal surface is round and smooth.
The diameter indicates the base of the rib, or rather the external measurement including in one calibre four petal shapes, two opposite two.
The width indicates the measurement in millimetres of the difference between the external and the internal surface. The number of ribs means the number of grooves between one petal shape and the next.
Our tubes are proposed in commercial length, approximately in a range between 4.500 mm 5.500 mm. However, they can be cut in a fixed length, e.g. bars of 5.000 mm, or proposed already cut to pieces in the required sizes, i.e. rings of 30 mm.
The packaging can be arranged on request in bundles protected by bubble wrap or in wooden crates.
