Heavy Duty Composite Manhole Cover | SMC Round Manhole Cover

Detailed Product Description

Composite Manhole Cover

Our Composite Manhole Covers are designed as a lightweight and durable alternative to traditional metal manhole covers. Manufactured from high-strength composite materials such as SMC, GRP, or FRP, these covers offer excellent corrosion resistance, low maintenance requirements, and easy handling.

The covers are available in round and square designs, with different dimensions, load ratings, surface patterns, colors, and locking options to meet various project requirements.

Key Specifications

*Load classes should be selected according to the actual product design and applicable testing standard.

Material

SMC (Sheet Molding Compound) is a commonly used material for composite access covers. It combines resin with reinforcing fibers and other additives to provide good mechanical strength, weather resistance, and corrosion resistance.

Depending on project requirements, GRP or FRP composite materials can also be supplied.

Main Features

• Lightweight Design – Easier transportation, handling and installation.
• Corrosion Resistant – Suitable for wet, humid and chemically exposed environments.
• Non-Conductive – Suitable for electrical and telecommunication infrastructure.
• Anti-Slip Surface – Helps provide safer access in wet conditions.
• Low Theft Risk – Composite materials have little scrap value compared with cast iron.
• Long Service Life – Designed for outdoor and underground infrastructure applications.
• Customizable – Size, logo, color, markings and locking systems can be customized.
