Introduction: Why GP Pipes Matter for Modern Projects
For engineers, contractors, purchase managers, and project planners, choosing the correct steel pipe is a technical decision with direct impact on safety, performance, and lifecycle cost. Yet many teams still treat GP Pipes as a commodity item instead of a carefully engineered material choice.
Asian Steels, part of the Asian Group of Companies based in Ahmedabad, Gujarat, supplies MS Pipes, GP Pipes, and GI Pipes to critical projects across India. As a manufacturer of steel pipes in India, the company works closely with industrial clients to ensure that the right pipe type is selected for each application.
This guide explains in clear, technical language what GP Pipe is, how it is manufactured, how it compares to MS and GI alternatives, and where it should be specified. By the end, you will have a practical framework for deciding when GP Pipes are the correct solution for construction, furniture, scaffolding, pipe fencing, industrial frameworks, and engineering applications.
What Is GP Pipe? A Technical Definition
India’s industrial growth has rapidly increased the demand for reliable, standardized steel pipes. GP Pipes have become a key element in this ecosystem because they match typical Indian project conditions: variable humidity, partially sheltered structures, and value-conscious budgets.
As a manufacturer of steel pipes in India, Asian Steels focuses its GP Pipe portfolio on real-world Indian environments rather than theoretical lab conditions. This means considering:
- Local humidity and temperature cycles
- Dust, pollution, and industrial atmosphere
- Common fabrication practices in Indian workshops
- Typical maintenance intervals on construction and industrial sites
For buyers, working with a manufacturer of steel pipe that understands these conditions helps avoid over-specification (unnecessary cost) or under-specification (premature failures).

How GP Pipes Are Manufactured: Step-by-Step
1. Coil Selection and Slitting
The process begins with mild steel coils that meet defined chemical and mechanical parameters. Control over carbon content, yield strength, and elongation is essential.
Coils are slit into strips of precise width for each pipe size. A responsible manufacturer of steel pipe ensures slit edges are clean and burr-free to support sound welding and straightness.
2. Forming and High-Frequency Welding
The strips are progressively formed into a circular or square profile using roll-forming mills. Once the edges meet, high-frequency welding creates a continuous longitudinal seam.
At this stage, the product resembles MS Pipes such as MS ERW Black Pipe and MS Square/Rectangular Steel Pipes, which can either be supplied as MS or further processed into GP Pipes.
3. Sizing, Straightening, and Cutting
The tube passes through sizing rolls to bring it to final dimensions. Straightening machines ensure linearity, and pipes are cut to length using cold saws or flying cutters.
4. Galvanization and Surface Conditioning
The steel tubes are galvanized with zinc. The coating is optimized for indoor and under-roof environments and provides good paint adhesion.

GP Pipes vs MS Pipes vs GI Pipes
GP Pipes vs MS Pipes
MS Pipes provide structural capability but no inherent corrosion protection. GP Pipes include a zinc coating for improved resistance to rust. For indoor frameworks and furniture structures, GP Pipes are often the better choice.
GP Pipes vs GI Pipes
GI Pipes have heavier zinc coatings and are designed for high-exposure conditions. GP Pipes are better for precision structural use with clean aesthetics and tight dimensional control.
Key GP Pipe products: GP Round Steel Pipe and GP Square & Rectangular Steel Pipes.
Performance Characteristics
- Mechanical Strength: Suitable for light to medium loads.
- Corrosion Resistance: Zinc coating delays rust formation.
- Dimensional Accuracy: Tight tolerances for visible and fabricated applications.
Major Applications
Construction
Used in railings, staircase guards, canopy supports, and more. A steel pipe manufacturer in Gujarat like Asian Steels can supply cut-to-length GP Pipes for jobsite efficiency.
Furniture
GP Pipes enable modular and durable furniture, racking, and shelving systems. Also used with CRCA Coil Steel Sheets for complementary fabrication.
Scaffolding
Provides strength, corrosion resistance, and workability for scaffolding systems.
Pipe Fencing
Ideal for factory perimeters and institutional fencing in semi-exposed conditions.
Industrial Frameworks
Supports cable trays, light mechanical frames, and walkways. Refer to: Applications.
When to Use GP Pipes
- Semi-exposed or indoor settings with moderate humidity
- Furniture, partitions, and painted visible structures
