Elbows and Bends

Used to change the direction of flow in a piping system, available in various angles.

Hybrid Strength

Combining helical and hoop winding in a single pipe allows for optimized performance, leveraging the axial strength from the helical winding and the circumferential strength from the hoop winding. This hybrid approach provides a well-rounded mechanical profile, suitable for demanding applications. Combined Winding can make Leverages the strengths of both patterns to create pipes with optimized performance, tailored to specific industrial needs.

Helical Winding

Provides enhanced axial strength, flexibility, and impact resistance, making it suitable for multi-directional load applications.

Hoop Winding

Offers superior circumferential strength, pressure resistance, and structural integrity, ideal for high-pressure and high-burst applications.


By adjusting the proportions and angles of helical and hoop windings, manufacturers can customize the mechanical properties of GRP pipes to meet specific requirements, offering tailored solutions for various industries. The combined winding patterns ensure balanced load distribution and enhanced durability, making the pipes resistant to both internal and external stresses, including thermal expansion, vibrations, and mechanical impacts.

Tees and Crosses

Allow for branching of pipelines, providing multiple flow paths.


Facilitate easy connection and disconnection of pipes to other pipes or equipment.


Connect pipes of different diameters, ensuring a smooth flow transition.


High Strength-to-Weight Ratio

GRP pipes and fittings exhibit excellent mechanical high strength-to-weight ratio while being lightweight and extremely strong, making them easier to transport and install. GRP pipes and fittings can be adapted for use in both above-ground and underground installations, as well as in harsh and demanding environments.


Join two sections of pipe together, maintaining structural integrity and sealing.

Corrosion Resistance

GRP pipes and fittings are highly resistant to a wide range of chemicals and corrosive substances, including acids, alkalis, and salts. This makes them ideal for use in chemical processing, wastewater treatment, and other corrosive environments. its significantly extends the service life of the pipes, reducing the need for frequent replacements and maintenance.


Resistant to UV radiation, weathering, aging and environmental degradation, which enhances longevity. This makes them suitable for outdoor applications where exposure to the elements is a concern. GRP Pipes & Fittings ensures a long operational lifespan, which contributes to lower lifecycle costs.
