EN124 D400 Heavy Duty 250x1000mm Ductile Iron Trench Drain Grating with Frame

Product Description

High-Performance Linear Drainage for High-Traffic Infrastructure

We engineer stormwater management solutions that stand up to the toughest environments. Our 250x1000mm D400 slotted drainage grating delivers the ideal combination of rapid water intake and brute structural strength, mitigating urban flooding risks while securing traffic flow.

• Strict EN124-4 Class D400 Certification: Fully compliant and certified under European Standard EN 124-4:2015. Rated for a 400kN (40 Tons) test load, making it exceptionally safe for main traffic highways, gas stations, dockyards, and commercial busy avenues.

• Optimal 250x1000mm Modular Dimensions: The standard 1-meter length allows for fast, continuous linear alignment along trench runs, minimizing labor installation time and providing a flush fit with concrete or polymer channel systems.

• High-Volume Water Intake Slots: Designed with precision-spaced parallel bars that optimize water catchment efficiency during torrential rain, while safely ensuring that vehicle tires and commercial machinery can cross over without hazards.

• Durable Ductile Iron GGG50 Material: Unlike brittle traditional cast iron, our spheroidal graphite iron offers immense tensile strength and elastic limits. It withstands repetitive heavy-wheel impacts without cracking or deforming over decades of service.

• Anti-Rattle & Stability Design: Precision-molded grates fit snugly into their matching heavy-duty ductile iron outer frames. This stable fit, combined with optional locking points, prevents annoying rattling noise and displacement under rapid traffic.

• Ultimate Anti-Rust Finishing: Treated with a thick, heavy coat of black bitumen or premium epoxy powder paint, offering superior barrier protection against road salts, chemical spills, and industrial runoff.
