FRP Manhole Cover With Frame

Product Description

An FRP Manhole Cover with Frame typically includes the following components and features, designed for durability, load-bearing, and resistance to corrosion, especially in harsh or chemically aggressive environments:

Components of an FRP Manhole Cover with Frame:

1. FRP Manhole Cover (Lid):

   • Made from Fiber Reinforced Plastic (FRP) ” a composite material of resin (like polyester or epoxy) reinforced with glass fibers.

   • Can be circular, square, or rectangular depending on application.

   • Non-corrosive, non-conductive, and lightweight compared to cast iron or concrete.

   • Load rated (e.g., A15, B125, C250, D400) as per EN 124 standards.

2. FRP Frame (Rim/Base):

   • Supports the cover and distributes load to the surrounding surface.

   • Also made of FRP or in some cases, cast iron for added strength.

   • Fixed into concrete or pavement.

3. Locking Mechanism (Optional):

   • Some models include locking bolts or latches to prevent unauthorized access or theft.

   • Tamper-proof designs are available.

4. Sealing Gasket (Optional):

   • Rubber or neoprene gasket for watertight or odor-proof sealing.

   • Often used in sewage or telecom applications to prevent water ingress or gas leakage.

5. Lifting Keyholes or Handles:

   • Moulded-in or built-in keyholes to lift the cover using standard tools.

   • Some may have embedded metal parts to reinforce these areas.

Design Features:

• Slip-Resistant Surface: Anti-skid design (textured or patterned).

• UV Stabilized: Suitable for prolonged outdoor exposure.

• Chemical Resistant: Suitable for sewer lines, chemical plants, etc.

• Non-Sparking & Non-Conductive: Ideal for electrical or explosive environments.

Typical Applications:

• Sewer and drainage systems

• Telecom and electrical manholes

• Utility vaults

• Roadways, sidewalks, and industrial plants

• Gas and water pipelines
