Hot-dip galvanized steel pipe in Light (A), Medium (B) & Heavy (C) class, DN15–DN150, screwed & socketed or plain-end. Held available across Qatar, the UAE and Saudi Arabia for water, plumbing, fire-fighting and fabrication — with material test certificates.
GI pipe stands for Galvanized Iron pipe — a mild steel pipe coated with a protective layer of zinc by hot-dip galvanizing. The zinc coating shields the steel from rust and corrosion, giving the pipe a long service life in water and outdoor environments. GI pipe is one of the most widely used pipes for water supply, plumbing, fire-fighting and general fabrication across the GCC.
GI pipe is manufactured to BS 1387, EN 10255 and ASTM A53, hot-dip galvanized to BS EN ISO 1461, and supplied in three wall-thickness classes — Light (Class A), Medium (Class B) and Heavy (Class C) — from DN15 (½″) to DN150 (6″), either screwed & socketed or plain-end.
Thinnest wall, lowest pressure rating. General low-pressure water & non-critical lines.
The most common class — plumbing, water distribution and structural use. Best all-round balance.
Thickest wall, highest pressure rating. Fire-fighting mains and higher-pressure service.
