About FRP MANHOLES

An FRP (Fiber Reinforced Plastic) manhole cover is a durable, lightweight composite access cover made from thermoset resins, fiberglass reinforcement, and fillers, designed to replace traditional cast iron or concrete covers.

Description & Material Composition

Core Material: Manufactured using a blend of unsaturated polyester, vinyl ester, or epoxy resins combined with chopped strand mats or woven roving fiberglass reinforcement.

Key Traits: Non-corrosive, non-conductive, UV-resistant, and features zero scrap resale value which prevents theft.

Surface: Typically finished with an anti-slip coating and self-pigmented, fade-resistant color options.

Technical Specifications

Load Ratings & Categories:
- Low / Light Duty (2.5 to 5 tons): Suitable for pedestrian zones, sidewalks, and residential pathways.
- Medium Duty (10 to 12.5 tons): Used for light commercial driveways and parking lots.
- Heavy / Extra Heavy Duty (20 to 40+ tons): Engineered for heavy vehicular traffic, highways, and industrial facilities.

Compliance Standards: Tested and manufactured in accordance with international norms like BS EN-124, IS 1726-1991, and ASTM standards.

Standard Shapes & Clear Opening Sizes:
- Circular: Diameters typically ranging from 315 mm to 900 mm.
- Square / Rectangular: Common sizes include 300x300 mm, 450x450 mm, 600x600 mm, up to 1200x900 mm.

Weight Range: Varies from 1020 kg (light duty) to 4060+ kg (heavy duty/high load capacity), making them significantly lighter than cast iron alternatives
