RF700-80 Series High-Performance SMC Round Manhole Covers for Fuel Stations and Industrial Roads

RF700-80 Series High-Performance SMC Round Manhole Covers for Fuel Stations and Industrial Roads

The RF700-80 series heavy-duty round manhole covers is a reliable solution for areas requiring high mechanical strength, environmental resistance, and long-term durability. Designed with a cover diameter of 700 mm and a sturdy frame structure, this series is ideal for fuel stations, municipal roads, sidewalks, and industrial facilities, offering both safety and convenience for inspection and maintenance.

Manufactured entirely from SMC (Sheet Moulding Compound) composite material, the covers and frames provide exceptional chemical resistance, waterproofing, and UV protection, making them suitable for challenging environments. The NBR (Nitrile Butadiene Rubber) sealing ring ensures a tight, watertight, and chemically resistant connection, preventing water, fuel, or acidic/alkaline substances from penetrating underground chambers.

The RF700-80 series complies with EN124:1994 standards and is available in B125 (12.5-ton), C250 (25-ton), and D400 (40-ton) load classes, accommodating light to heavy vehicle traffic. The frame inner diameter is 650 mm, outer diameter 790 mm, and total height 80 mm. Its locking mechanism with removable seal ensures secure operation while facilitating inspection and maintenance.

The cover’s raised anti-slip pattern provides excellent traction even in wet or oily conditions. Compared to traditional cast iron covers, this series is lightweight yet strong, with cover weights ranging from 15 kg (B125) to 25 kg (D400) and a frame weight of 10 kg, making installation, handling, and maintenance safer and more efficient. Clients can also request custom colors or logo engraving to meet aesthetic or branding needs.

Internationally, this series is referred to differently depending on the region: in Egypt as SMC manhole cover, in Nigeria as composite access cover, in Spain as tapa de registro SMC, in Portugal as tampa de inspeção em SMC, in the United States as GRP round manhole cover, and in Russia as композитный люк SMC. Despite the varied terminology, the core benefits remain consistent: durable, load-bearing, chemically resistant, anti-static, and inspection-friendly.

In summary, the RF700-80 series heavy-duty round SMC manhole covers provide a robust, safe, and maintenance-friendly solution for fuel stations, urban roads, and industrial sites. Lightweight yet strong, they are a perfect alternative to traditional cast iron covers, offering long service life, environmental resilience, and operational convenience.
