Ductile Iron Integrated Gully Grate / Curb Inlet Grate

The ductile iron integrated gully grate is a one-piece integral drainage inlet product specially designed for municipal road drainage, sidewalk water collection, community rainwater discharge and highway drainage systems. Adopting high-strength ductile iron material and one-piece casting molding, this integrated rainwater grate features high toughness, strong compression resistance, no breakage, stable structure and perfect fitting performance. It effectively collects surface rainwater, accelerates drainage speed, prevents road ponding, and greatly improves road safety and drainage efficiency. Integral design avoids loose components, eliminates displacement and noise caused by vehicle rolling, and achieves long-term stable operation in outdoor harsh environments.

This integrated ductile iron gully grate is widely used in municipal infrastructure drainage projects. It is suitable for urban road sidewalks, motor vehicle lanes, residential communities, scenic parks, urban squares, highways and bridge drainage systems. It is the core supporting product for surface rainwater collection and rapid drainage.

Compared with traditional split rainwater grates, our integrated ductile iron grate adopts one-piece casting, which fundamentally solves the problems of grate shaking, noise, dislocation and easy loss. Ductile iron material provides stronger bearing capacity and better toughness, avoiding brittle fracture in cold weather. The overall structure is more durable with lower maintenance rate, which is more in line with the long-term use requirements of municipal and highway engineering.
