Galvanized Iron (GI) Pipes in Pakistan
Galvanized iron pipe is steel pipe protected by a hot-dip zinc coating that shields the base metal from rust and moisture. It remains the most widely used pipe for water supply, plumbing, fire-fighting and irrigation work in Pakistan — durable, easy to install and economical over a long service life.
A. Karimjee & Sons supplies GI pipes from 1/2″ to 8″ to ASTM A53, ASTM A795 and BS EN 10255, in plain end or threaded and coupled configurations.
