RF980-100 Series Heavy-Duty Round SMC Manhole Covers with Inspection Hole
The RF980-100 series heavy-duty round manhole cover with inspection hole is engineered for demanding applications where high mechanical strength, environmental resistance, and operational convenience are essential. Its large cover diameter of 980 mm makes it ideal for fuel stations, municipal infrastructure, industrial facilities, and other locations that require both heavy vehicle traffic tolerance and secure underground access.
Crafted entirely from high-performance SMC (Sheet Moulding Compound) composite, both the cover and frame deliver excellent resistance to chemicals, moisture, and ultraviolet radiation. This material also provides anti-static protection, which is critical for fuel handling areas, industrial zones, or any environment with flammable substances. The RF980-100 series meets EN124:1994 standards, ensuring compliance with international safety and quality benchmarks.
Designed for C250 (25-ton) and D400 (40-ton) load classes, the RF980-100 can handle heavy traffic while maintaining stability and integrity. The frame has an inner diameter of 900 mm and an outer diameter of 1070 mm, while the cover and frame stand 100 mm high, creating a robust, low-profile solution that is both safe and practical. Its integrated locking mechanism and removable seal simplify inspection and maintenance operations without compromising sealing or safety.
The product features NBR (Nitrile Rubber) sealing rings, which resist acids, alkalis, and fuels, forming a tight waterproof barrier. This effectively protects the underground chamber and equipment from groundwater, spills, and debris. The cover surface is designed with a raised anti-slip pattern, providing reliable traction for vehicles and personnel under wet or oily conditions.
With its lightweight construction relative to traditional cast iron alternatives, the RF980-100 cover is easier to handle during installation or maintenance. The standard weight ranges from 60 kg for C250 covers to 70 kg for D400, with the frame weighing approximately 16 kg. Customers can request custom colors or logo engraving, allowing the cover to blend with the environment or reflect corporate branding.
Internationally, this series may also be referred to as SMC composite inspection cover, GRP round access hatch, composite manhole cover with monitoring hole, or fuel station heavy-duty cover, depending on regional naming conventions. Regardless of the term, its core strengths remain consistent: durability, load capacity, corrosion resistance, anti-static safety, and inspection-friendly design.
In summary, the RF980-100 series offers a large, secure, and maintenance-friendly manhole cover solution suitable for heavy-duty applications where performance, safety, and environmental resistance are critical. It is an ideal replacement for traditional cast iron or steel covers, providing ease of use, long service life, and enhanced operational safety.
