Metal Stormwater Grates

Residential landscape paths and school sidewalks require drainage covers that provide both effective water management and pedestrian safety. The drainage surface must allow water flow while preventing common walking hazards, such as narrow-heel shoes becoming trapped or pedestrians slipping on wet surfaces.

Our Dingjian metal stormwater grates are designed for these applications. The model is 30060040 channel cover, with a load capacity of 120 kN and a B125 load rating. Made from ductile iron, these grates are suitable for residential green paths, school sidewalks, park landscapes, and other pedestrian drainage areas.

The narrow slot design of these metal stormwater grates helps improve safety in high-traffic pedestrian areas. The slot width is carefully controlled to reduce the risk of narrow-heel shoes becoming trapped. This feature is especially useful for commercial walkways, office areas, and school environments.

The optimized slot structure also helps prevent larger debris, such as leaves and waste, from entering drainage pipes. This keeps the drainage system cleaner and reduces maintenance requirements. Even spacing between slots ensures efficient water flow and helps prevent surface water accumulation during heavy rainfall.

Ductile iron provides excellent strength, toughness, and impact resistance for landscape drainage applications. This is a key advantage of metal stormwater grates compared with composite alternatives.

Under the same load requirements, ductile iron offers better structural reliability and durability. If a small maintenance vehicle or light vehicle accidentally passes over the drainage area, the grate can withstand the pressure without cracking or breaking.

Compared with stainless steel solutions, ductile iron provides a more cost-effective choice for light-load landscape drainage systems while maintaining reliable long-term performance.
