4 – 16 mm (outside diameter): 6000 + 100 mm
18 – 42 mm (outside diameter): 6000 + 50 mm

Tubes with outside diameter < 16 mm can be delivered in coils. The length of coil: 60 m – 400 m.

outside diameter 4 mm – 30 mm tolerance +/- 0,08 mm
outside diameter 35 mm – 38 mm tolerance +/- 0,15 mm
outside diameter to 42 mm tolerance +/- 0,20 mm
tolerance of inside diameter according to EN 10305-4
tolerance of wall thickness +/- 10%

8-12 µm, usually it is more than 10 µm. Upon agreement thickness of the plating can be >10 µm, >15 µm, >20 µm. Thickness >25 µm is not recommended.
