The star-shaped tube is characterised by a star-shaped geometric polygon section.
The diameter indicates the basis of the star, or rather the external measurement including in one calibre four star points, two opposite two. The thickness of the tube, which indicates the measurement in millimetres of the difference between the external and the internal surface.
The number of points is the number of vertices of the triangle components in the star-shaped polygon.
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.
