Types of Plumbing Pipes Materials – MS, GI, SS & More
Choosing the right plumbing pipe material is critical for ensuring durability, safety, and cost-effectiveness in water supply and industrial projects. With multiple options like MS, GI, SS, copper, the selection depends on usage, budget, and environmental conditions.
Why Pipe Material Matters in Plumbing
Every plumbing system faces unique challenges – pressure, corrosion, hygiene, and cost. The right pipe material ensures long service life and prevents issues like leaks, rust, and water contamination.
Types of Plumbing Pipes Materials
1. Mild Steel (MS) Pipes
MS pipes are strong, affordable, and commonly used in structural plumbing and fabrication. However, they are prone to rust if not coated.
- Durability: Medium
- Corrosion Resistance: Low without coating
- Applications: Plumbing for sheds, fabrication, temporary water lines
2. Galvanized Iron (GI) Pipes
GI pipes are zinc-coated MS pipes, offering better corrosion resistance. They are widely used for domestic plumbing and water supply.
- Durability: Good
- Corrosion Resistance: High
- Applications: Household plumbing, rural water supply
3. Stainless Steel (SS) Pipes
SS pipes, especially SS 304 and SS 316, are highly resistant to corrosion and scaling. They are ideal for hygienic applications like drinking water and food processing.
- Durability: Excellent
- Corrosion Resistance: Very High
- Applications: Drinking water, pharma, industrial use

4. Copper Pipes
Copper is known for its durability and resistance to bacteria. It is commonly used in premium plumbing systems. However, it is costly compared to MS or GI pipes.
5. PVC (Polyvinyl Chloride) Pipes
Lightweight and easy to install, PVC pipes are widely used in residential plumbing. They are not suitable for high-temperature applications.
6. CPVC (Chlorinated Polyvinyl Chloride) Pipes
CPVC pipes can handle hot water and are stronger than standard PVC pipes.
7. PEX Pipes
PEX is flexible and easy to install, making it popular in modern plumbing, especially in housing.
