EN124 Heavy Duty SMC Composite Manhole Cover for Energy and Road Projects

Our SMC/FRP composite manhole covers represent the next generation of infrastructure materials designed for modern cities and industries. Manufactured from high-strength Sheet Molding Compound (SMC) reinforced with fiberglass, these covers combine durability, safety, and environmental performance in one product. Unlike traditional cast-iron covers, they are lightweight, non-corrosive, and completely free from scrap value theft risk.

Each cover is molded under high temperature and pressure, ensuring uniform strength and long-term stability. The material’s high load-bearing capacity allows it to withstand repeated heavy traffic loads, while its anti-slip surface pattern ensures pedestrian safety even in wet conditions. With zero metal components, the cover is resistant to rust, chemicals, and extreme weather, making it ideal for municipal roads, residential communities, water treatment plants, and telecommunication chambers.

Elite’s composite covers are available in round, square, or rectangular designs, and can be customized with logos, text, and specific surface textures. The products are manufactured in compliance with the EN124 standard, offering options from light-duty to heavy-duty classes. Each item undergoes strict testing for load capacity, water absorption, and impact resistance to guarantee consistent quality.
