Product Overview

Galvanized steel pipe(galvanized pipe), Galvanised steel pipe(galvanised pipe)

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 material

2.Mechanical and general engineering purposes

3.Manufacturing of Bus Body, Railway Boogies

4.In Telephone department as Conduit Pipes 

Types: Galvanzied welded steel pipe, galvanzied seamless steel pipe

Materials: Carbon steel

Connection type: threaded


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).
