Product Description

Industrial Grade FRP Manhole Cover – Built for Extreme Conditions

Industrial environments demand materials that perform reliably under harsh chemical and mechanical stresses. Elite’s Industrial Grade FRP manhole cover was engineered precisely for these conditions, offering unparalleled resistance to corrosion, impact, and temperature extremes.

Made from glass-fiber-reinforced SMC composite, it withstands exposure to oils, acids, alkalis, and industrial solvents, making it ideal for chemical plants, refineries, and wastewater treatment facilities. Unlike metal alternatives, the composite structure does not corrode or react with surrounding substances, ensuring long service life and low maintenance.

The cover’s mechanical strength supports load ratings up to D400, providing durability in areas where forklifts, heavy trucks, or machinery operate. The non-conductive surface ensures electrical insulation in energy or communication facilities. Each unit can include optional bolt locks and rubber seals for enhanced safety and environmental protection.

A key advantage of this FRP cover is its dimensional stability — it does not deform under temperature swings from -60°C to +100°C. Elite’s proprietary molding technology ensures uniform density and smooth surfaces on both sides, making it easy to clean and inspect.

Customers can request embossed identification codes, customized markings, or functional design adjustments to integrate with industrial flooring systems. This product stands as a cost-effective and long-lasting replacement for cast iron or steel covers, combining industrial strength with composite innovation.

FRP Access Cover with Double Seal – Odor-Proof and Leak-Resistant Solution

Elite’s FRP Access Cover with Double Seal system is designed to meet the highest standards for sealing performance in drainage and wastewater applications. It prevents both surface water ingress and internal gas or odor leakage, ensuring sanitary and environmentally friendly operation.

The system integrates two independent sealing layers — a high-performance EPDM gasket and an inner groove compression ring — that create a double barrier between the cover and the frame. This ensures complete protection even under heavy traffic and pressure.

Manufactured from high-strength fiberglass-reinforced polymer composite, the product combines durability with lightweight structure. Its corrosion-resistant nature makes it ideal for coastal installations, sewage treatment plants, or industrial chemical sites. Unlike metal covers, it requires no painting, never rusts, and offers a clean, modern appearance.

Elite’s precision manufacturing guarantees tight tolerances and smooth operation, even after years of use. The product can be customized with locking mechanisms, hinges, or lifting keys to meet site-specific needs. Optional ventilation holes or inspection ports can be integrated without compromising sealing performance.

This double-sealed manhole cover helps utilities meet strict environmental standards and odor-control regulations while maintaining easy access for maintenance teams. By combining mechanical integrity, chemical resistance, and smart design, it provides a superior long-term solution for urban and industrial drainage systems.
