FRP Manhole Cover Grating

FRP Manhole Cover Grating About

SIPL - FRP manhole cover comes in various combinations with respect to load capacity, size, shape, and adherence to standards like BS EN 124 or IS 1726, with common capacities from 2.5 tons to 40 tons, shapes including square, circular, and rectangular, and sizes ranging from small utility covers (e.g., 600x600mm) to heavy-duty highway versions. Key features include lightweight design, anti-corrosion properties, anti-slip surfaces, and high strength, making them superior to cast iron alternatives for various traffic and pedestrian applications. 

Key Specifications

         Load Capacity:

o    Light Duty: 2.5T (Pedestrian areas, driveways).

o    Medium Duty: 5T, 10T, 12.5T (Service lanes, car parks).

o    Heavy Duty: 20T, 25T, 40T (City trunk roads, industrial areas, highways).

         Shapes: Square, Circular, Rectangular.

         Sizes (Clear Opening): Varies widely, e.g., 530x530mm, 600x600mm, up to large rectangular sizes (e.g., 450x600mm).

         Material: Fiberglass Reinforced Polymer (FRP) composite, often SMC/DMC (Sheet/DMC Molding Compound).

         Standards: BS EN 124, IS 1726. 

Common Features

         Lightweight: Easier handling and installation.

         Anti-Corrosive & Chemical Resistant: Durable in harsh environments.

         Anti-Slip Surface: Enhanced safety.
