GI stands for “galvanized iron.” Thus, GI pipes are galvanized iron pipes or called coated iron pipes in old terminology. GI carbon steel pipes are immersed in a galvanic (zinc) bath. GI (Galvanized Iron) Pipes are classified into 3 grades based on their weight per meter and inner diameter thickness. The more the thickness, the better the performance and durability. According to the IS 1239, each pipe shall bear a color strip across the circumference for identifying the “class” of the GI pipes. These pipes are cheaper, of lightweight and easy to handle.
