Pre-Galvanised Hollow
Section Pipes

MANUFACTURING PROCESS

GP hollow-section pipes are manufactured by slitting GP coils and forming them into hollow sections through precision roll forming, followed by Electric Resistance Welding (ERW). The coils are galvanised using an advanced Non-Ox Continuous Galvanizing Line (CGL), which prevents oxidation during the process and eliminates surface defects such as black spots, white rust, or peel-offs. Before forming, every coil is tested for hardness, and after welding, the pipes undergo oven baking to ensure complete dryness and prevent moisture-related corrosion. Each pipe then undergoes three stages of inspection and batch-level bend and flattening tests to ensure coating integrity, dimensional accuracy, and long-term reliability.

APPLICATIONS

Construction & Infrastructure:These are widely used for both residential and commercial foundations, solar plants, windmill frameworks, and other renewable energy infrastructures.

Greenhouse: These pipes are ideal for durable greenhouse structures.

Coastal and humid regions: Reliable choice for marine and seaside structures as it resists rust.
