As a trusted manufacturer with over five years of expertise in metal fabrication, Hengshui Ruibin New Materials LLC is proud to present our Heavy Duty Trench Grating for Highway Drainage Systems, designed to meet the stringent requirements of EN 1433 Class F900. These gratings are engineered for the most demanding traffic loads, ensuring long-term durability and safety on highways, airports, and industrial zones. Our commitment to quality is backed by a mill test report supplied with every delivery, providing full traceability of material properties.
Our trench gratings are manufactured using high-grade steel reinforcement, combining superior strength with efficient water drainage. The F900 load class (tested to withstand 900 kN static load per EN 1433) guarantees reliable performance under heavy wheel loads and repetitive traffic. Whether you require standard sizes or custom dimensions, our flexible production line can accommodate your project needs. Below we detail the key features, technical specifications, and advantages that make our product a preferred choice for infrastructure projects worldwide.
Key Features & Technical Specifications

Frequently Asked Questions (FAQ)
Q1: Does the grating meet F900 load class as per EN 1433?
Yes, our product is tested to withstand a static load of 900 kN and a dynamic fatigue load of 250 kN, fully complying with EN 1433 Class F900 requirements. The mill test report confirms the material properties.
Q2: Can you supply gratings in non-standard sizes?
Absolutely. We offer custom dimensions, slot widths, and thicknesses. Just provide your design drawings or load requirements, and our engineering team will tailor the product accordingly.
Q3: What surface treatment do you recommend for coastal environments?
For coastal or highly corrosive environments, we recommend hot-dip galvanizing with a minimum coating thickness of 85 µm. Alternatively, an epoxy coating system can be applied for added protection.
Q4: How is the grating packed for export?
Standard packing includes steel pallets or wooden crates, with protective spacers between layers to prevent damage. LCL and FCL shipments are both supported.
Q5: Can you provide a mill test report (MTR) for each batch?
Yes, a mill test report is supplied with every shipment, detailing the chemical composition and mechanical properties of the steel used.
Q6: What is the typical lead time for an order of 100 pieces?
For standard sizes, lead time is approximately 15–20 working days after confirmation of the order and receipt of deposit. Custom orders may require 25–30 days.
Q7: Do you offer samples before bulk production?
Yes, we can provide pre-production samples (paid or free depending on quantity) for your quality evaluation. Shipping cost is typically borne by the buyer.
Q8: Is the product suitable for airport runways?
Yes, the F900 load class is specifically designed for areas subjected to extreme wheel loads, including airport runways, aircraft parking aprons, and heavy industrial zones.
