Galvanized Iron (GI) Pipe
Hot-dipped galvanized to BS EN 10255:2004 in Grades L, M and H
- BS EN 10255:2004
- BS EN 10226:2004

Hot-dipped galvanized iron pipe manufactured in accordance with BS and ASTM standards. We hold attention on each stage of the process — manufacturing, galvanizing and finishing — with quality control and inspection at every step.
The range covers Grade L, Grade M and Grade H to BS EN 10255:2004 (formerly BS 1387:1985) — Grade L from 15 to 100 mm, Grade M from 15 to 150 mm and Grade H from 40 to 150 mm nominal bore. Threading is cut to BS EN 10226:2004.
GI pipe is our most-specified product for potable water: the zinc coating carries it well past the service life of black pipe in the same duty, and it will hold hydro pressure up to 50 bar.
