Galvanized steel pipes are made of steel that has been covered with a layer of zinc metal. During the galvanizing process, we immerse the steel in a molten zinc bath, ensuring a tough, uniform barrier coating.
Application:
1.Building and structural material2.Mechanical and general engineering purposes3.Manufacturing of Bus Body, Railway Boogies4.In Teledepartment as Conduit Pipes

Length of the galvanized tubesin diameter 4 - 16 mm 6000 + 100 mmin diameter 18 - 42 mm 6000 + 50 mmTolerances of the zinc coated tubes- tolerances of the outside diameter:diameter between 4 - 30 mm ±0,08 mmdiameter between 35 - 38 mm ±0,15 mmdiameter 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 tubesE 235+N and E 355+NSurface condition of the galvanized tubesFirst layer â electrolitically leached zinc (Zn) â 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).
