The Ductile Iron Trench Grating with Heel-Proof Slots, Width 100mm, Load Rating D400 for Highway Use is designed to meet the rigorous demands of heavy traffic areas while ensuring pedestrian safety. This product combines exceptional strength, durability, and advanced slot design to provide an efficient drainage solution without compromising on safety.
Product Overview:
This trench grating is crafted from high-grade ductile iron, offering superior tensile strength and impact resistance compared to gray cast iron. The 100mm width makes it ideal for narrow drainage channels in highways, pedestrian crossings, and road shoulders. The heel-proof slots are specifically engineered to prevent high-heel shoes, bicycle tires, or small objects from getting caught, enhancing safety for both pedestrians and cyclists. With a load rating of D400 (tested to withstand up to 400 kN), this grating is suitable for highway applications where heavy vehicle loads are expected.
- Material: Ductile iron (EN GJS-500-7 or equivalent) for high strength and ductility.
- Width: 100 mm (custom widths available upon request).
- Load Rating: D400 per EN 124 standard, suitable for carriageways and highways.
- Slot Design: Heel-proof slots with narrow openings (typically ≤ 20 mm) to prevent shoe heel entrapment.
- Surface: Anti-slip pattern (e.g., raised crosshatch or studs) for enhanced traction.
- Corrosion Resistance: Available with hot-dip galvanized or bitumen coating options.
- Installation: Compatible with standard concrete or metal frames.
- Customization: Length, coating, and frame type can be customized to project requirements.

Frequently Asked Questions (FAQ):
-
Q: What is the maximum load capacity of this grating?
A: The D400 load rating means it can withstand a test load of 400 kN (approximately 40 tons) per EN 124 standard, making it suitable for highways and areas with heavy vehicle traffic. -
Q: Can the grating be used in areas with frequent snow and ice?
A: Yes, the ductile iron material has good low-temperature toughness, and the anti-slip surface helps maintain traction. We recommend a hot-dip galvanized coating for enhanced corrosion resistance if road salt is used. -
Q: Are the slots truly heel-proof?
A: Yes, the slot openings are designed to be narrow (typically less than 20 mm) to prevent high-heel shoes, bicycle tires, and small debris from lodging. This design is tested to meet safety requirements for pedestrian areas. -
Q: What lengths are available?
A: Standard lengths include 500 mm, 1000 mm, and custom lengths up to 3000 mm. Please contact us with your specific requirements for a quote. -
Q: Does the product come with a frame?
A: The grating can be supplied with or without a matching frame. We offer standard frames made of ductile iron or steel, and customization is available. -
Q: How is the grating packaged for export?
A: Products are packaged in strong wooden crates or steel pallets with proper cushioning to prevent damage during transit. We ship from Port of Tianjin or Port of Qingdao. -
Q: What is the typical lead time?
