FRP Manhole Covers — Lightweight, Corrosion-Proof Access Solutions for India's Infrastructure
FRP manhole covers are lightweight composite access covers made from Fibre Reinforced Plastic, designed to seal underground utility access points including sewage lines, storm drains, water pipes, electrical conduits and chemical storage tanks. Unlike steel covers that rust or concrete covers that crack and weigh 60+ kg, FRP covers are 80-90% lighter, non-conductive, corrosion-proof and maintain their integrity for 30-50 years without maintenance.
Rawji Exports is a Mumbai-based FRP manhole covers manufacturer, operating from its own facility in Bhiwandi since 1962. We manufacture custom-sized FRP manhole covers, gratings, access covers and lids, and supply them directly to municipal corporations, water authorities, wastewater treatment plants, industrial facilities, and infrastructure projects across Mumbai, Thane, Pune, Delhi, Hyderabad, Bangalore and PAN India — with no middlemen or reseller markup.

FRP manhole covers are used to safely seal access points to underground utilities including sewage lines, storm drains, water distribution pipes, electrical conduits, telecommunications cables, and chemical or hazardous waste storage tanks. They are commonly used in municipal infrastructure, wastewater treatment plants, industrial facilities, airports and highway installations.
FRP manhole covers offer several advantages: they are 80-90% lighter than steel or concrete, making them easier to handle and transport; they are non-conductive, eliminating electrical shock hazards; they resist corrosion, rot and chemical damage; they require zero maintenance unlike steel covers which rust; they don't rust or attract thieves like steel covers; and they last 30-50 years without degradation.
Yes, FRP manhole covers are highly safe and durable. They are designed to support heavy loads (up to 3-5 tonnes depending on size), resist harsh chemicals and corrosive environments, withstand UV and extreme weather, and last 30-50 years. They are non-conductive, making them safe around electrical installations and are certified by ISO standards.
Rawji Exports manufactures FRP manhole covers in custom sizes starting from 300mm to 1200mm diameter and beyond. Standard sizes include 400mm, 500mm, 600mm, 750mm and 900mm. Thickness ranges from 10mm to 25mm depending on load requirements. We offer both solid covers and grated covers (gratings) for ventilation applications.
FRP manhole covers are significantly lighter than traditional materials. A typical 600mm FRP cover weighs 8-12 kg compared to 45-55 kg for a steel cover of the same size. Concrete covers of the same size can weigh 60-80 kg. This 80-90% weight reduction makes FRP covers much easier to handle, install and transport.
Yes, FRP manhole covers are excellent for harsh chemical environments. They are resistant to acids, alkalis, solvents, oils and most industrial chemicals. They do not corrode, rust or degrade when exposed to chemical spills, sewage or contaminated water—making them ideal for chemical plants, refineries, wastewater treatment and hazardous waste facilities.
