Product Description

Product Description

Integral Ductile Iron Rainwater Gully Grate

Integral ductile iron rainwater gully grate is one-time integral casting of grate and outer frame from QT500-7 spheroidal graphite iron, a complete one-piece rainwater inlet assembly complying with GB/T23858-2021 and EN124 standards. Unlike split separate grate and frame, the integral structure eliminates assembly gaps, improves overall compression and anti-displacement capacity; equipped with hinge flip, silent buffer and anti-slip texture. Widely used for flat pavement rainwater collection on municipal roads, residential districts, plazas and factory passages.

Product Features:

Monolithic Integral Casting Superior Rigidity: No assembly gap of split grate & frame, greatly reduce dislocation, sinking and pavement cracking risks, higher overall structural stability.

QT500-7 High Toughness Anti-break Performance: Avoid brittle crack failure of grey cast iron under heavy truck impact and ground settlement deformation.

Built-in Hinge Captive Anti-theft System: Grate never fully separated from integral frame, drastically cut theft maintenance replacement cost.

One-piece Simplified Construction: Only one component to place and anchor during installation, fewer parts, faster paving construction than split sets.

Integrated Silent Rubber Buffer Fit: Perfect sealing without gap loosening, long-lasting noise reduction effect superior to separately installed rubber strips.
