GI & GP Pipe

GI and GP pipes are both galvanized steel pipes, meaning they’re coated with zinc to prevent rust and corrosion, but they can differ slightly in their manufacturing and intended use; GI (Galvanized Iron) typically refers to pipes that have undergone a hot-dip galvanization process, resulting in a thicker zinc coating and making them ideal for heavy-duty applications like plumbing and water supply, while GP (Galvanized Plain) pipes often refer to those made from pre-galvanized steel, which may have a thinner coating and are commonly used in lighter applications such as fencing and scaffolding, though the terms are often used interchangeably.
