Ductile Cast Iron Trench Drain

Product Description I. Core Structure & Design 1.Space-Optimized Dimensions 300×500mm rectangle at 40mm height – engineered for narrow roadside channels, greenbelt inlets, and residential pathways. Outperforms standard grates (e.g., 480×750) in sub-30cm trenches where larger units fail. 2.High-Efficiency Hydraulics V-flow profile: Grating bars angled at 15° funnel water centrally, boosting flow 30% 25mm wide drainage slots at 30mm spacing balance flow rate and clog resistance 3.Modular Rapid-Install System M16 anchor holes at corners enable 5-minute bolt-down installation Concrete-gripping teeth beneath frame enhance shear resistance II. Five Critical Advantages 1.Clog-Free High Flow for Extreme Weather 15mm narrow slots (smaller than typical debris) resist typhoon leaf blockages 45° sloped slot walls accelerate drainage – 40% faster than flat grates 3cm bottom clearance extends silt cleaning cycles to 3 months 2.Crack-Proof Pedestrian Safety Honeycomb structure + ductile iron toughness delivers 40-ton capacity. Withstands e-bikes/service vehicles without deformation or brittle failure ("trap holes"). 3.Theft/Silence Integration Zero scrap value: Asphalt-coated surface makes theft unprofitable EPDM dampened frame reduces noise to ambient levels (zero residential complaints) 4.Corrosion Resistance & Zero Maintenance Ductile iron + asphalt coating survives acid rain/deicers/fertilizers for 20+ years No repainting (vs. steel grates) – only silt removal required III. Engineering Adaptability 1.Enhanced Safety R2 radius bar edges increase shoe contact by 40% Recessed 3-5mm below pavement prevents heel trapping 2.Dynamic Load Endurance ≤0.1mm deformation after 200k cyclic load tests (simulating light vehicles) 3.Anti-Theft & Economy Anchor bolts cast integrally – removal requires destructive cutting Self-cleaning + hinge lubrication-free design minimizes upkeep IV. Key Applications Micro-drainage nodes: Residential walkways, park trails, parking lot edges High-cleaning zones: Restaurant alleyways, wet market outlets Harsh environments: Coastal resorts, chemical plant perimeter roads Conclusion: Small Grate, Mighty Impact The 300×500×40 ductile iron grate is urban drainage’ssilent sentinel. Its honeycomb structure bears accidental loads, narrow slots filter storm surges, and maintenance-free operation lightens municipal burdens. Next time you walk an alley, notice these humble grids – they keep our cities resilient through storms.
