What Are GI Pipe Classes?

GI pipes are categorized into three main classes based on thickness and weight:

  • Light Class (Class A)
  • Medium Class (Class B)
  • Heavy Class (Class C)

These classifications determine strength, durability, and suitability for different applications.

Light Class GI Pipes (Class A)

Light class GI pipes are thinner and lighter, making them cost-effective and easy to handle.

Products like MS ERW GI Pipes are commonly available in this category.

Features

  • Lower thickness
  • Lightweight
  • Cost-effective

Applications

  • Low-pressure water systems
  • Indoor plumbing
  • Temporary structures

Light pipes are suitable for projects where budget is a priority and load requirements are minimal.

Medium Class GI Pipes (Class B)

Medium class GI pipes offer a balance between strength and cost, making them the most commonly used category.

Features

  • Moderate thickness
  • Balanced durability
  • Suitable for multiple applications

Applications

  • Residential plumbing
  • Construction frameworks
  • Industrial usage

They are often considered when deciding which GI pipe is best for construction in general-purpose projects. 

Heavy Class GI Pipes (Class C)

Heavy class GI pipes have the highest thickness and strength, designed for demanding applications.

Features

  • Maximum thickness
  • High strength and durability
  • Long lifespan

Applications

  • High-pressure pipelines
  • Industrial systems
  • Infrastructure projects

Heavy pipes are ideal as best GI pipes for long term use where performance and reliability are critical. 

GI Pipe Thickness and Weight Comparison

In a GI pipe thickness and weight comparison, the difference between classes becomes clear:

  • Light → Thin walls, lower weight
  • Medium → Moderate thickness
  • Heavy → Thick walls, higher weight

This directly affects strength, durability, and cost.
