C250 Reinforced Round Utility Manhole Cover

• The Industry’s Only Publicly Listed Company: BAOGAI is the sole publicly listed corporation in China’s composite manhole cover sector. For our international partners, this means absolute financial transparency, audited quality control, and the long-term reliability required for major residential developments. We are a partner that stands by its warranty.
• Direct In-house Mold Factory: A perfect manhole cover fit requires high-precision tooling to prevent “rocking” or “tilting” when vehicles pass over. Because we operate our own mold factory, we ensure a high-precision fit. This also allows us to offer Elite OEM Customization—integrating your logo or specific utility text (e.g., “SEWER”, “WATER”) into the mold with speed and direct-factory pricing.

Key Product Benefits

• High-Load Stability (C250 Rated): Tested to 25 tonnes, this cover comfortably handles light to medium vehicular traffic, making it perfect for road verges and commercial parking areas.
• Personnel Access Safety: The large Φ800mm design provides a generous clear opening, allowing maintenance workers with equipment to enter and exit underground chambers safely and efficiently.
• Corrosion & Rust Proof: Unlike ductile iron, BMC is inherently resistant to salt, moisture, and chemical runoff. It requires zero maintenance and will not seize in the frame over time.
• Anti-Theft & “Zero Recovery Value”: As a composite material, it has no scrap value. This eliminates the risk of theft on public roads, protecting your infrastructure and the public from “open pit” hazards.
• Quiet Urban Environment: The natural vibration-damping properties of BMC, combined with our precision-molded fit, ensure the cover remains silent even under traffic—no more “metal clanging” in residential or commercial zones.

Target Applications

• Municipal Roadways: Kerbside channels and verges (within 0.5m of the road edge).
• Industrial Sites: Factory drainage networks and loading bay perimeters.
• Commercial Infrastructure: Shopping mall car parks and hospital utility access.
• Telecommunications: Large-scale underground fiber optic chambers.

FAQ

Q1: Can this C250 cover be used in the middle of a high-speed highway?

A: No. According to EN124 standards, C250 is suitable for kerbside areas and parking lots. For main carriageways and highways with high-speed heavy traffic, we recommend our D400 SMC series.

Q2: How does being a listed company benefit my order?

A: It means we are subject to regular government and financial audits, ensuring we follow ethical labor practices and use only high-grade raw materials. You get a “peace of mind” guarantee that the product delivered matches the technical data sheet 100%.

Q3: Is the Φ800 measurement the “Clear Opening” or the “Frame Diameter”?

A: Φ800 is the external frame diameter. The clear opening is typically 700mm, providing a standard unobstructed access point for personnel as per international safety guidelines.

Q4: Can you emboss our city’s crest or company logo on the cover?

A: Yes. Thanks to our in-house mold factory, we can create custom-branded covers with very low lead times. We can even provide a 3D mock-up of the logo for your approval before production.
