Round Stormwater Grate

Low-lying overflow pits and garage collection pits play an important role during heavy rainfall. When water reaches a certain level, the overflow system needs to release excess water into connected drainage pipes to reduce flooding risks in low areas.

Our round stormwater grate features a circular overflow design that adds automatic overflow capability to traditional drainage systems. When the water level inside the pit exceeds the preset height, excess water flows through the overflow opening. This design helps improve drainage efficiency and reduces flooding risks.

The product is suitable for low-lying overflow pits, garage collection pits, riverside overflow areas, and other locations requiring additional water release functions.

The load capacity of this round stormwater grate can be adjusted from 30 kN to 500 kN, covering applications from pedestrian areas to heavy vehicle zones.

We can customize wall thickness and rib structures according to different load requirements. This flexibility allows customers to select the appropriate configuration based on actual traffic conditions instead of using oversized heavy-duty products for low-load areas.

The adjustable structure helps optimize both performance and project cost.

The circular structure eliminates sharp corners and helps distribute external forces more evenly. Compared with square designs, the round shape reduces stress concentration points and improves overall structural stability.

No matter which direction vehicle pressure is applied, the load is transferred across the entire circular structure. This design helps extend service life and improves reliability during long-term use.

The built-in filter layer provides additional protection by blocking large debris from entering the overflow opening. The filter can be removed for cleaning, making routine maintenance simple and convenient.
