GRP Manhole
SUPERLIT's GRP Manhole solutions stand out in the industry for their durability and reliability. Our manholes, made from Glass Fiber Reinforced Polyester (GRP), provide excellent performance in infrastructure projects.
GRP
The SUPERLIT GRP Manhole, which has a wide range of applications from water and wastewater management systems to industrial facilities, has been designed and manufactured in accordance with international standards.
What is a GRP Manhole? GRP Manholes are made from composite materials consisting of glass fiber reinforced thermosetting resin and silica sand. This combination of materials provides manholes with high strength, corrosion resistance, and long life. GRP Manholes can be used in both underground and above-ground applications, meeting a variety of industrial needs.
SUPERLIT GRP Manholes are used in water and wastewater management systems, industrial facilities, chemical plant piping lines, power plant circulation lines, and hydroelectric power transmission lines. They are also preferred in stormwater and drainage systems, sewer lines, and submarine pipeline applications.
Advantages of GRP Manholes
GRP Manholes stand out for their long-lasting and durable structure. These manholes offer a service life of at least 50 years, providing excellent corrosion resistance and reliable performance across a wide pH range. Their lightweight structure makes them easy to transport and install. Compared to steel, ductile iron, and concrete manholes, GRP Manholes are much lighter, do not require special equipment for installation, and allow for quick setup.
SUPERLIT GRP Manholes feature a smooth inner surface that reduces hydraulic losses and minimizes friction, enabling efficient water and wastewater transmission. They provide secure connections with watertightness ensured by full-face (Full-Face®) integrated elastomeric gasket couplings.
Quality and Safety
SUPERLIT manufactures GRP Manholes in accordance with the highest quality standards. Produced to meet EN, ISO, ASTM, and AWWA standards, our manholes cater to a wide range of diameters and pressure classes. Our products offer reliable, durable, and efficient solutions for your engineering projects.
SUPERLIT’s GRP Manhole solutions are an environmentally friendly choice for sustainable projects, being made from recyclable materials. With their long service life and eco-friendly nature, SUPERLIT GRP Manholes are a reliable option for your infrastructure projects.
