Aluminium tubes - Length 3 m.

Aluminium Tubes Length 3 meter with 2,5 mm or 5 mm wall thickness.

The round aluminium tubes are made of alloy 50ST. This means that the aluminium used is reinforced and has following mechanical specifications::

Min. torque	:	22 kg/mm2
0,2 yield strength	:	min. 16 kg/mm2
Strain	:	10 x d min. 10%
Hardness	:	HB 10 ca. 70 kg/mm2

The aluminium tubes with outer/inner diameter above are available in lengths of 2 m, 3 m. and 6 m. Sizes length, outer diameter and inner diameter are in mm.

Attention when adding alu tubes with different diameters to construct a telescopic mast. If inner diameter is the same as outer diameter of the next section, sections will not fit without correction!
