Linear Ductile Iron Drainage Grates

Core Product Advantages
Extreme Load Bearing & Safety
Engineered with high tensile strength and ductility, these grates easily meet load classes from D400 (Arterial Roads) to F900 (Airport Runways). They are designed to deform under extreme pressure rather than suffer brittle fractures.
Lightweight Efficiency
Despite their strength, these grates are significantly lighter than traditional grey iron alternatives. Paired with a boltless rapid-locking system, they ensure faster installation and effortless maintenance for cleaning.
Noise Reduction & Anti-Displacement
Featuring precision-fit tolerances and anti-vibration designs, our grates eliminate "clattering" noises when vehicles pass. The locking mechanism prevents bouncing or longitudinal shifting caused by frequent heavy braking.
Superior Corrosion Resistance
Treated with high-performance anti-rust coatings, the grates are resistant to acids, alkalis, and oxidation. They maintain structural integrity even in harsh industrial environments or high-salinity coastal areas.
Optimized Drainage & Anti-Slip Surface
Scientifically calculated open areas ensure instantaneous water intake during heavy storms, while the cast-in raised patterns provide excellent skid resistance for both vehicles and pedestrians.

Typical Applications
Heavy-Duty Hubs: Airports, seaports, logistics parks, and gas stations.
Municipal Works: Highways, urban main roads, and bus terminals.
Industrial Sites: Factory heavy-vehicle lanes and loading docks.
