Bandhan - FRP Man Hole Cover
Bandhan FRP — Lightweight • Corrosion-resistant • Load-rated • Theft-proof
Bandhan FRP Man Hole Covers are high-performance composite access covers engineered for modern infrastructure — offering excellent strength, long life in corrosive environments, and drastically reduced handling weight compared with traditional metal covers.
Bandhan FRP Man Hole Covers are manufactured from high-strength fiberglass reinforced polymer (FRP) resins and glass fibres using precision moulding techniques. Designed for municipal, industrial and commercial projects, these composite covers combine a superior strength-to-weight ratio with excellent chemical and UV resistance — making them an ideal modern alternative to cast iron and concrete access covers.

Faqs
What is an FRP manhole cover?
An FRP (Fibre-Reinforced Polymer) manhole cover is a composite access cover made from glass fibre and resin. It combines high strength with low weight and excellent resistance to corrosion and chemicals.
Are FRP covers as strong as cast iron?
FRP covers are engineered to meet standard load classes (A15 to D400 and above) and can match required performance in most pedestrian, commercial and many vehicular areas. Cast iron remains superior for some extreme heavy-duty applications; Bandhan offers D400 and higher rated FRP solutions for robust use-cases.
Do FRP covers corrode?
No — FRP is inherently corrosion-resistant and performs well in sewage, coastal and chemical environments where metal covers would corrode.
How much lighter are FRP covers?
Depending on size and load class, FRP covers typically weigh between 15–25% (or less) of equivalent cast-iron covers — significantly easing manual handling and transport. Exact savings depend on design and materials.
Are FRP manhole covers theft-proof?
FRP covers have negligible scrap value, and with lockable designs they are effectively theft-resistant compared to metal covers.
