FRP Manhole Covers
Rawji Exports has been manufacturing FRP manhole covers in India since 1962, supplying municipal, industrial and infrastructure projects across the country. Our fiberglass reinforced plastic covers are moulded to resist corrosion, UV exposure and repeated load cycles — conditions that gradually degrade cast iron and concrete covers over time.
Unlike cast iron, FRP manhole covers have no scrap-metal resale value, which is why municipal and telecom projects increasingly specify them for unsecured locations prone to theft. They're also significantly lighter, so a single site worker can lift and reposition a cover without lifting equipment — a real difference on drainage and cable-trench projects with hundreds of access points.
We manufacture FRP manhole cover sizes from 300x300mm up to 900x900mm, in round, square and rectangular designs, with load ratings from 5 tons for pedestrian areas up to 40 tons for highway and heavy industrial use. Every cover is built to the load class the site actually needs, rather than a one-size-fits-all rating.
FRP manhole cover price in India depends on size, load class and design — a 5-ton pedestrian cover costs less than a 40-ton industrial cover, so we quote based on your project's actual specification. As a direct FRP manhole cover manufacturer, Rawji Exports supplies bulk orders with PAN India delivery for government, municipal and private infrastructure projects.

Standard Specifications
- FRP manhole covers are moulded from thermoset composite material engineered for long-term durability under repeated load.
- The material combines cross-linked polyester resin with fiberglass reinforcement, built to withstand wear from heavy vehicular traffic without cracking or degrading.
- 40% lighter than traditional precast concrete and cast iron covers of the same load rating.
- Provides up to 5 times more compressive strength than standard concrete covers.
- Withstands constant exposure to weather and direct sun without losing structural integrity or surface finish.
Advantages of FRP Manhole Covers
- No scrap resale value, which significantly reduces theft compared to cast iron covers.
- Light enough to handle without lifting equipment, reducing injury risk for site workers.
- Does not rust or degrade from chemical exposure, sewage or rainwater contact.
- Longer service life than metal covers, since the material doesn't corrode and resists high-impact loads.
- Self-pigmented finish means no periodical repainting is required for maintenance.
- Pigments are UV-stabilized and built into the material itself, so colour doesn't peel or fade from sunlight exposure.
- Performs consistently across extreme temperature ranges without becoming brittle or warping.

Frequently Asked Questions - FRP Manhole Covers
FRP manhole covers are used for sewerage chambers, storm water drainage, telecom chambers, wastewater treatment plants, cable trenches and municipal utility access points — anywhere corrosion resistance and theft-resistance matter more than raw weight-bearing mass alone.
For corrosive or unsecured locations, yes — FRP manhole covers don't rust, have no scrap-metal resale value (so they're rarely stolen), and are around 40% lighter than cast iron covers of the same load rating, making them easier for a single worker to lift and reposition.
Rawji Exports manufactures FRP manhole covers in standard sizes from 300x300mm up to 900x900mm, in square, rectangular and circular shapes, with custom sizes available for non-standard chamber openings.
Yes. Load ratings range from 5 tons for pedestrian and light-traffic zones up to 40 tons for highway and heavy industrial applications, so the cover is matched to the site rather than over- or under-specified.
Price depends mainly on size and load class — a 5-ton pedestrian cover costs significantly less than a 40-ton industrial-rated cover. Rawji Exports offers factory-direct pricing with bulk discounts for municipal and industrial orders.
FRP manhole covers, being fiberglass reinforced plastic articles, generally fall under HSN code 3925. Contact Rawji Exports for the exact HSN code and GST rate applicable to your order.
Yes. The cross-linked polyester and fiberglass composite doesn't absorb water or react with sewage chemicals, which is why these covers hold up in coastal areas and continuous wet-chamber conditions where cast iron would eventually rust through.
Yes, Rawji Exports manufactures customized FRP manhole covers in different sizes, shapes, colours and load capacities based on project specifications and infrastructure requirements.
