When it comes to steel piping solutions for construction, fabrication, furniture, and industrial frameworks, the three most common choices are MS Pipes, GI Pipes, and GP Pipes. Each of these steel pipes serves a specific purpose based on its material composition, protective coating, and performance requirements.
At Asian Group of Companies (Asian Steels), a trusted manufacturer of steel pipes in India, we understand that choosing the right type of pipe can directly influence the longevity, safety, and cost-efficiency of your project. This detailed guide explains the differences between MS, GI, and GP pipes, their uses, and which one is best suited for your application.
Understanding Steel Pipes and Their Importance
Steel pipes are essential components in almost every sector — from construction and infrastructure to manufacturing and furniture design. Their strength, formability, and reliability make them an ideal choice for both structural and fluid-carrying applications.
Whether you are building a residential structure, assembling scaffolding, or designing industrial frameworks, the type of steel pipe you select will determine the overall durability and corrosion resistance of your system. Choosing the right pipe also helps optimize maintenance costs and improve safety performance.
As one of India’s most reputed manufacturers of steel pipes, Asian Steels produces a comprehensive range of MS Pipes, GI Pipes, and GP Pipes engineered for consistent quality and long service life.
What Are MS Pipes?
Definition and Composition
MS Pipes, short for Mild Steel Pipes, are made from low-carbon steel. They typically contain a small percentage of carbon (around 0.05–0.25%), which makes them softer and more malleable than high-carbon steels. This low carbon content gives MS pipes their characteristic weldability, ductility, and ease of forming.
Manufacturing Process
MS pipes are generally produced using hot-rolled or cold-formed steel strips, which are shaped into circular, square, or rectangular sections and welded along the seam. The weld is then heat-treated to ensure strength and uniformity.
At Asian Group of Companies, our MS Black Pipes and MS GI Pipes are manufactured under strict quality control systems, ensuring excellent mechanical properties and consistent wall thickness.
Features and Advantages of MS Pipes
- High Strength: Offers robust performance for structural and mechanical use.
- Easy to Weld and Bend: Ideal for fabrication and construction.
- Cost-Effective: Lower initial cost compared to galvanized alternatives.
- Versatile Applications: Suitable for both industrial and general engineering projects.
Applications of MS Pipes
- Construction Frameworks: Used for columns, beams, and trusses.
- Furniture Fabrication: Common in tables, racks, and support frames.
- Scaffolding Structures: Widely used for temporary construction platforms.
- Industrial Support Systems: Excellent for mechanical supports and machinery frameworks.
- Pipe Fencing: Used for durable, easy-to-install barriers.
What Are GI Pipes?
Definition
GI Pipes, or Galvanized Iron Pipes, are steel pipes that have been coated with a protective layer of zinc. This coating prevents corrosion and rusting caused by moisture or chemical exposure.
Manufacturing Process
The galvanization process involves dipping mild steel pipes into molten zinc, ensuring that the zinc layer adheres firmly to the steel surface. This coating acts as a physical barrier against corrosion and provides sacrificial protection, meaning the zinc corrodes first before the steel underneath is affected.
Key Features and Benefits
- Superior Corrosion Resistance: Ideal for environments exposed to water, humidity, or outdoor weather.
- Extended Lifespan: The zinc coating enhances durability and reduces maintenance costs.
- High Tensile Strength: Strong enough for heavy-duty applications.
- Leak-Proof Joints: Suitable for water supply and fluid transport systems.
Applications of GI Pipes
- Plumbing and Water Supply Lines: Commonly used in residential and commercial systems.
- Outdoor Construction: Perfect for structures exposed to rain and sun.
- Scaffolding Systems: Ensures longer life compared to plain MS pipes.
- Agricultural and Irrigation Systems: Reliable for water distribution and borewell piping.

What Are GP Pipes?
Definition
GP Pipes, or Galvanized Plain Pipes, are manufactured from cold-rolled GP sheets that are zinc-coated through a continuous electro-galvanizing process. Unlike GI pipes that are hot-dipped, GP pipes get their coating through electroplating, resulting in a smoother, shinier finish and precise surface uniformity.
Manufacturing Process
GP pipes start as cold-rolled coils that are zinc-coated through electro-galvanization. These sheets are then formed into pipe shapes and welded. Because the process is carefully controlled, the resulting pipes have an even, thin zinc layer that provides excellent corrosion protection for indoor and light outdoor use.
Features and Advantages
- Aesthetic Appearance: Smooth, shiny surface suitable for visible structures.
- Corrosion Resistance: Provides moderate protection against rust.
- Lightweight: Easier to transport and handle than GI pipes.
- Excellent Workability: Ideal for precision fabrication.
Applications of GP Pipes
- Furniture and Fixtures: Widely used in office and home furniture.
- Automotive Frameworks: Suitable for body structures and light vehicle components.
- Display and Storage Racks: Attractive surface finish ideal for commercial interiors.
- General Fabrication Work: Used wherever light, clean steel sections are required.

MS vs GI vs GP Pipes — Understanding the Differences
Although all three types are made from steel, they differ mainly in their zinc coating process, corrosion resistance, and intended applications.
1. Coating and Protection
- MS Pipes: Have no protective coating; therefore, they are prone to rust when exposed to moisture.
- GI Pipes: Are hot-dip galvanized, creating a thick zinc layer that provides excellent corrosion protection.
- GP Pipes: Are electro-galvanized, resulting in a thin, smooth zinc layer suitable for aesthetic and light applications.
2. Corrosion Resistance
GI and GP pipes both resist corrosion better than MS pipes. GI pipes have the highest protection because of their thicker zinc coating, making them suitable for outdoor and water-related applications. GP pipes, while resistant to mild corrosion, perform best in indoor or low-moisture conditions.
3. Appearance and Finish
MS pipes have a dull, dark grey look. GI pipes appear silver-grey with a matte texture due to the hot-dip zinc coating. GP pipes, on the other hand, have a bright, polished silver appearance — making them visually appealing for interior and visible installations.
4. Strength and Durability
All three are structurally strong, but their longevity varies. GI pipes generally last the longest because of their heavy zinc coating. MS pipes are durable but may need painting or regular maintenance to prevent rust. GP pipes have moderate strength and are best suited for light to medium applications.
5. Cost Considerations
MS pipes are the most economical. GI pipes cost slightly more because of the galvanization process, and GP pipes usually fall between the two — offering a good balance of protection and aesthetics at a reasonable price.
6. Applications
- MS Pipes: Construction, scaffolding, fencing, and furniture.
- GI Pipes: Plumbing, outdoor structures, irrigation, and water lines.
- GP Pipes: Furniture, automotive frames, and decorative frameworks.
How to Choose the Right Steel Pipe for Your Project
Selecting between MS, GI, and GP pipes depends on the environmental exposure, budget, and the functional requirement of your project.
Choose MS Pipes if:
You need a cost-effective and strong material for structural applications such as scaffolding, furniture, or general frameworks that will be painted or kept indoors.
Choose GI Pipes if:
Your project involves water flow, outdoor exposure, or contact with moisture, such as in plumbing, irrigation, or external fencing.
Choose GP Pipes if:
You need a lightweight, corrosion-resistant pipe with a smooth finish for furniture, automotive, or aesthetic installations.
If you’re uncertain about which pipe best suits your requirements, the technical experts at Asian Group of Companies can guide you based on your project’s environment and design load.
