Hengshui Ruibin New Materials LLC is a professional manufacturer specializing in high-quality drainage solutions since 2019. Our Galvanized Steel Trench Grating EN 1433 Class C250 is designed to deliver exceptional load-bearing performance and long-term durability for demanding infrastructure projects. This grating combines a 250mm width with hot-dip galvanized anti-slip surface treatment, making it an ideal choice for heavy-duty drainage applications where safety and reliability are paramount. With our factory spanning 1,000-3,000 square meters and an annual export value of US$2.5-5 million, we ensure consistent quality and timely delivery to clients worldwide.
Each trench grating is manufactured to meet the stringent requirements of the EN 1433 standard, specifically engineered for Class C250 load capacity (up to 25 tons). The 250mm width is optimized for standard drainage channels in roads, parking areas, and pedestrian zones. The hot-dip galvanized coating provides superior corrosion resistance in harsh environments, while the specially designed anti-slip pattern reduces accident risks even in wet conditions. Below are the key technical specifications:
| Parameter | Value |
|---|---|
| Material | Hot-dip galvanized steel (Q235B or equivalent) |
| Width | 250mm (±2mm) |
| Load Class | C250 (tested per EN 1433) |
| Surface Treatment | Hot-dip galvanized (≥65μm coating thickness) |
| Anti-Slip | Diamond / mesh pattern (slip resistance ≥ R12) |
| Length | Customizable (standard 1m, 1.5m, 2m, 3m) |
| Weight (per meter) | Approx. 15-20 kg (depending on bar spacing) |
| Bar Spacing | 30mm / 40mm / 50mm (custom available) |
Key advantages of our Galvanized Steel Trench Grating:
- High Load Capacity: C250 class supports static loads up to 25 tons, suitable for vehicular traffic including cars and light trucks.
- Corrosion Resistance: Hot-dip galvanization (HDG) provides a durable protective layer that withstands salt, chemicals, and moisture for decades.
- Anti-Slip Safety: The patterned surface (diamond or cross-hatch design) ensures excellent traction for pedestrians and vehicles, even when wet or icy.
- Easy Installation: Lightweight yet robust design allows for quick placement into standard channel frames. No special tools required.
- Customizable Dimensions: Length, bar spacing, and edge details can be tailored to your project requirements with a short lead time.
- Low Maintenance: The smooth galvanized finish resists debris buildup and is easy to clean with water or air.
Our trench gratings are widely used in municipal drainage systems, parking lots, airport aprons, warehouse floors, and pedestrian walkways. The combination of strength and anti-slip properties makes them particularly suitable for areas with heavy foot traffic or frequent vehicle movement. Compared to cast iron alternatives, our steel grating offers better strength-to-weight ratio and easier handling during installation.

Frequently Asked Questions (FAQ)
Q1: What does Class C250 load capacity mean?
A: According to EN 1433, C250 class gratings are designed to withstand static loads up to 250 kN (approximately 25 tons). They are suitable for areas with pedestrian and light vehicular traffic, such as sidewalks, parking lots, and driveway entrances.
Q2: Is the hot-dip galvanized coating environmentally friendly?
A: Yes, hot-dip galvanizing is a sustainable process. The zinc coating is recyclable, and the long service life reduces the need for replacements. Our process complies with relevant environmental standards.
Q3: Can I get custom lengths or different bar spacings?
A: Absolutely. We offer custom lengths from 0.5m to 3m per piece, and bar spacings from 20mm to 60mm. Please provide your specific requirements for a tailored solution.
Q4: How do I fix the grating into the channel?
A: The grating is designed to rest on a frame or channel edge with a secure fit. For permanent installation, we recommend using locking clips or bolts (sold separately). Temporary placement is also possible for maintenance access.
Q5: What is the typical lead time for a standard order?
A: For standard sizes (250mm width, 1m length), lead time is approximately 15-20 days after order confirmation. Custom orders may take 25-30 days, depending on the quantity and complexity.
Q6: Do you provide samples for testing?
A: Yes, we can provide small samples (e.g., 250x300mm) for evaluation. Sample cost and shipping are negotiable. Contact our sales team for details.
Q7: Is this grating suitable for use in cold climates with de-icing salts?
A: Yes, hot-dip galvanized steel is highly resistant to corrosion from road salts and de-icing chemicals. It is a preferred choice for regions with harsh winters.
Q8: What certifications do you have for this product?
A: Our gratings are manufactured to comply with EN 1433 standard. We also have internal quality control procedures. Specific third-party certification reports are available upon request.
