Airport/Dock Extra Heavy Duty Gratings

Specifically engineered for ultra-heavy-duty environments such as airport runways and container terminals, our Extra Heavy Duty series represents the pinnacle of ductile iron engineering. Designed to withstand extreme dynamic impacts exceeding F900 (900kN), it is the most robust drainage solution for global infrastructure.

Core Features:
Ultimate Strength: Crafted from high-grade ductile iron with superior tensile strength and ductility, ensuring zero-fracture performance under heavy aircraft or container reach stackers.

Triple Stability System: Equipped with heavy-duty pressure locks and anti-vibration gaskets to eliminate grate "bounce" and metallic noise during high-speed taxiing.

Extreme Corrosion Resistance: Advanced deep-coating technology withstands high-salinity maritime mist and aviation fuel erosion, extending maintenance intervals by 50%.
