4" Pipe G.I Medium (6 Mtr).

• 4.0 inch Diameter: 4.5mm Thickness : 07 Gauge : 73.0 KG
• GI (Galvanized Iron) is steel, which has been galvanized by the application of a protective coating of zinc, which reduces rust and corrosion.
• GI replaced cast iron and lead pipes in the early 20th century as the staple plumbing pipe.
• GI pipes are preferred due to their strength and durability. These pipes have a life expectancy of about seventy years.
• However, pipe longevity depends on the thickness of zinc in the original galvanization and whether the pipe was galvanized on both the inside and outside or just the outside.
