   Length of the galvanized tubes

    - in diameter 4 - 16 mm 6000 + 100 mm

    - in diameter 18 - 42 mm 6000 + 50 mm

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).

   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%
