GI Steel Pipe vs GP Pipe: Know the Difference Before You Buy — A Thrissur Industry Insight

Introduction

In the world of construction and home improvement, steel pipes play a vital role — from water supply lines to structural frameworks and fabrication works. But when it comes to choosing between GI (Galvanized Iron) and GP (Galvanized Plain) pipes, many customers often get confused.

As a leading steel distributor in Thrissur, Luxarc Private Limited helps builders, contractors, and homeowners understand these materials better — ensuring they get the right product for the right application.

Here’s a clear look at how GI and GP pipes differ, and how Thrissur’s strong manufacturing network supports both categories.

What Is a GI Pipe?

GI (Galvanized Iron) pipes are made from mild steel strips that are hot-dip galvanized — meaning they’re dipped in molten zinc to form a thick, corrosion-resistant coating.

This process gives the pipe excellent durability, making it ideal for outdoor and heavy-duty use.

Key Features of GI Pipes (TATA)

• Superior corrosion resistance

• Strong and durable for long life

• Ideal for water supply, fencing, and outdoor applications

• Slightly rougher matte finish due to hot-dip process

Common Uses in Thrissur:

• Plumbing and borewell lines in residential and commercial buildings

• Scaffolding and structure work in Thrissur’s growing construction scene

• Outdoor fencing and fabrication across the city’s industrial zones

What Is a GP Pipe?

GP (Galvanized Plain) pipes are made from cold-rolled coils (CR sheets) that are electro-galvanized — a process that creates a thin, even layer of zinc on the surface.

They’re smoother, shinier, and more suitable for lightweight indoor fabrication.

Key Features of GP Pipes (APL APOLLO)

• Smooth, attractive finish

• Easier to bend and fabricate

• Lighter weight and cost-effective

• Best for indoor or decorative use

Common Uses in Thrissur:

• Interior fabrication works and furniture units

• Electrical conduit installations

• Decorative or indoor support structures
