Length of the galvanized tubes
in diameter 4 - 16 mm 6000 + 100 mm
in diameter 18 - 42 mm 6000 + 50 mm

Tolerances of the zinc coated tubes
- tolerances of the outside diameter:
diameter between 4 - 30 mm ±0,08 mm
diameter between 35 - 38 mm ±0,15 mm
diameter up to 42 mm ±0,20 mm
- tolerances of the inside diameter are according to EN 10305-4
- tolerance of the wall thickness ± 10%

The Steel grades for the zinc coated tubes
E 235+N and E 355+N

Surface condition of the galvanized tubes
First layer – electrolitically leached zinc (Zn) – acts as anode and in a corrosive environment it corrodes first and the base metal is cathodically protected against corrosion. The zinc layer thickness may be in the range of 5 to 30 micrometers (µm).
