Non-wheel GRP pipes - tailored to individual project needs
GRP non-circular pipes from Superlit are custom-made solutions - wherever standard diameters and shapes are not enough. Thanks to their fully customisable cross-section parameters, they are ideal for renovation projects, atypical sewer systems and in locations with limited installation space.
Supreno non-wheel GRP pipes - flexible solution for customised sections
Supreno non-wheel GRP pipes is an excellent choice for construction and renovation of non-pressure sewer networks. They are used, among other things, in repair, reinforcement and improvement of hydraulic conditions in collector basins, manholes and sewer chambers.
Made to order, in any size and shape, Supreno tubes provide Precise fitting to existing channels and full compliance with design requirements - even under the most difficult field conditions.

Eggs - Supreno GRP profile
Egg profile is most often used for channels with a strongly deformed cross-section. Thanks to its design, it allows optimum reproduction of the existing shape, while maintaining high hydraulic and structural strength.

Bell-shaped - GRP Supreno profile
Bell profile is a solution dedicated to the renovation of wide-bottomed canals. Its geometry allows for efficient cross-sectional representation and ensures structural stability in difficult ground conditions.

Pear-shaped - GRP Supreno profile
Pear profile is used when retrofitting channels with a narrow base and wider top section. This shape promotes efficient flow and optimises the hydraulic performance of the system.

Rectangular - Supreno GRP profile
Rectangular profile makes maximum use of the available space, thus ensuring the maximum possible flow, unattainable with other shaped pipes.
Other available Supreno GRP pipe shapes
For more unusual applications we also offer custom shapes, such as:
- Oval
- Parabolic
- Elliptical
- Elliptical flattened
- Bow barrel
Advantages of Supreno GRP pipes - flexibility, durability and high hydraulic performance
Supreno GRP pipes are an innovative solution dedicated to renovation projects and new sewer installations that require reliability, chemical resistance and maximum flow capacity. Thanks to customisable sizes and shapes for a specific project, Supreno pipes work well where other materials fail.
Maximising hydraulic performance
Improved flow efficiency is one of the key features of Supreno GRP pipes. Thanks to optimum cross-sectional shapes and smooth internal surfaces, the pipes minimise resistance to flow, which translates into improved hydraulic system efficiency and reducing operating costs.
Corrosion resistance
Supreno non-wheel GRP pipes show excellent resistance to aggressive environments, including waste water, groundwater or chemicals. Thanks to this no additional corrosion protection is required, which significantly reduces infrastructure maintenance costs.
High impact and abrasion resistance
The special design of the GRP pipes ensures high mechanical strength. The material is resistant to dynamic hydraulic loads, as well as abrasion caused by solid material flow, which guarantees trouble-free operation under difficult conditions.
Full design flexibility
GRP Supreno offers the possibility of the exact matching of the size and shape of the panels to a specific project. Regardless of the type of cross-section - egg-shaped, bell-shaped, rectangular or special - you can get a ideal fit with existing channels or new systems.
Service life min. 50 years
The service life of Supreno GRP pipes is up to over 50 years, which makes them an excellent long-term investment. The material retains its properties for decades, minimising the risk of failure and maintenance and replacement costs.
