Luzhongbao 500×500×45 Ductile Iron Square Grate: The Reliable Guardian of Urban Underground Pipe Networks
Core Features of 500×500×45 Ductile Iron Square Grate
Balanced Load-Bearing & Lightweight Design
Uses QT500-7 ductile iron (Tensile Strength ≥500MPa, Yield Strength ≥320MPa), offering excellent mechanical properties.
The 45mm thickness is scientifically designed to meet GB Class B (≥250kN) or Class A (≥400kN) load requirements for non-heavy-load areas (e.g., sidewalks, internal community roads, green belts, plazas) while effectively controlling product weight for easy transportation and installation.
Stable Anti-Theft & Safety Assurance
Equipped with patented concealed anti-theft hinges, tightly locking the grate to the frame to prevent unauthorized opening and accidental displacement, significantly reducing theft risks and ensuring public safety.
Stable structure ensures no noise or bouncing when vehicles or pedestrians pass, guaranteeing smooth and steady passage.
Superior Slip Resistance
The grate surface features meticulously designed high-friction anti-slip patterns (e.g., cross ribs, raised dots, or fish scale textures), significantly enhancing grip in rainy, snowy, or oily conditions.
Effectively prevents pedestrian slips, ensuring walking safety, especially suitable for high-traffic areas.
Precise Compatibility & Easy Maintenance
Standard 500mm×500mm square dimensions with strict tolerance control ensure perfect compatibility with matching frames for quick and efficient installation.
High flatness enables seamless integration with surrounding pavement, enhancing aesthetics and driving/walking comfort.
Robust construction, aging resistance, and minimal daily maintenance effectively reduce lifecycle costs.
Long-Term Weather & Corrosion Resistance
The ductile iron matrix offers inherent corrosion resistance advantages.
Surface is typically treated with enhanced anti-corrosion coatings (e.g., high-temperature asphalt spraying, epoxy resin coating, or hot-dip galvanizing), forming a dense protective layer.
Effectively resists urban environmental hazards such as moisture, acid rain, and de-icing salt erosion, significantly outlasting ordinary cast iron grates in service life.
The Luzhongbao 500×500×45 Ductile Iron Square Grate integrates standard versatility, reliable load-bearing capacity, high security, convenient maintenance, and extended lifespan. It stands as the preferred solution for square inspection wells in urban non-heavy-load areas, contributing to the construction of safe, aesthetically pleasing, and sustainable urban infrastructure.
