Hot Dipped Galvanised Pipes also called GI Pipes are carbon steel pipes that have been dipped in a protective zinc coating to prevent corrosion and rust.
The zinc provides a protective barrier against corrosion when exposed to the outdoor environmental elements and indoor humidity.
There are two types of galvanised pipe: hot dipped galvanised pipe and cold galvanised pipe.
Galvanised pipes are a cheaper alternative to stainless steel pipes, while maintaining comparable strength and protection against rust.
GI Pipes widely Applications
Uses of galvanised pipe include general fabrication, manufacturing, frames, construction, water and sewer lines, chemical processing, steel scaffolding, sprinkler and irrigation systems and automotive industry.
