Bearing the SUPERLIT signature, all processes in the Konya Organized Industrial Zone (OSB) Sections 3 and 6 Infrastructure Projects—from production and logistics to stockyard organization and on-site installation—were successfully completed.
Within the scope of this major infrastructure investment:
DN 400 – DN 2800 mm diameter range
More than 65,000 meters of GRP (Glass Reinforced Plastic – GRP) pipes
Over 1,500 project-specific GRP (Glass Reinforced Plastic – GRP) manholes
were utilized to deliver a long-lasting, high-performance system for wastewater and stormwater networks.
To ensure durability under aggressive soil conditions, Isophthalic Polyester Resin was selected. With a PN 6 pressure class (Nominal Pressure) and SN 10,000 stiffness (Nominal Stiffness), the project was designed to achieve maximum structural strength and operational reliability.
Thanks to the specially designed GRP (Glass Reinforced Plastic – GRP) manholes, the system provides:
100% watertightness
High chemical resistance
Hydraulic efficiency
Fast and easy installation
Long service life
As a result, the region’s infrastructure has been transformed into a modern, sustainable, and resilient system.
Reflecting its engineering expertise in real-world applications, SUPERLIT continues to add value to the infrastructure of one of Türkiye’s most important industrial zones.
SUPERLIT is the only pipe manufacturer in Turkey capable of producing glassfiber reinforced polyester (GRP) pipes using three different technologies: 'Continuous Filament Winding', 'Centrifugal Casting', and 'Helical Filament Winding'.
SUPERLIT is a subsidiary of KARAMANCI HOLDING.
