Technical Specifications

MAIN PARAMETER

Key Performance Advantages

• High-Load Durability: Engineered to handle 25-ton loads effortlessly. The 70mm reinforced frame provides deep anchorage in asphalt or concrete, preventing displacement under frequent vehicular movement.
• Strategic Anti-Theft Solution: Our BMC composite has zero scrap value, eliminating the motive for theft. This ensures urban safety and reduces long-term maintenance liabilities for municipal authorities.
• Advanced In-House Mold Accuracy: Thanks to our proprietary mold-making technology, the cover-to-frame tolerance is minimal. This ensures a silent, rattle-free performance, even in high-traffic residential or commercial areas.
• Extreme Corrosion Resistance: Unlike cast iron, our covers will not rust or degrade when exposed to salt, moisture, or industrial chemicals, extending the service life to over 30 years.
• Easy Handling & Installation: Despite its high strength, the composite material is 50% lighter than iron, reducing shipping costs and the need for heavy lifting equipment on-site.

Target Applications

• Residential Communities: Private driveways and garage entrances.
• Commercial Parking Lots: Shopping mall perimeters and office park access.
• Municipal Utilities: Water, gas, and telecommunication inspection pits in light traffic zones.
• Urban Greenery: Parks, gardens, and walkway maintenance access.
