Hengshui Ruibin New Materials LLC proudly presents our Heavy Duty Galvanized Steel Grating 5mm Serrated Surface, 40x100mm Spacing for Platform. As a trusted manufacturer based in Hengshui, Hebei, we have been delivering high-quality steel gratings since 2019, serving clients across North America, South America, Europe, Asia, Africa, and more. With an annual export value of US$2.5–5 million and a dedicated team of 101–200 skilled workers, we combine advanced production technology with rigorous quality control to ensure every panel meets the demands of heavy industrial platforms, walkways, and trench covers. This grating is engineered to provide exceptional load-bearing capacity, slip resistance, and long-term durability, making it the ideal choice for safety-critical environments.
Product Highlights:
- Heavy Duty Design: Made from high-strength galvanized steel with a minimum yield strength of 250 MPa, capable of supporting substantial loads.
- Serrated Surface: Each bearing bar features a serrated top edge that provides superior anti-slip performance, even in wet or oily conditions.
- Precise Spacing (40x100mm): The 40mm center-to-center distance between bearing bars and 100mm between cross bars ensures optimal load distribution and allows debris to fall through.
- Hot Dip Galvanized Finish: The entire grating is hot-dip galvanized after fabrication, offering long-lasting corrosion resistance for indoor and outdoor use.
- 5mm Bar Thickness: Bearing bars are 5mm thick, providing a perfect balance of strength and weight for easy handling and installation.

We welcome small trial orders and custom specifications – our experienced team will guide you from design to delivery.
Frequently Asked Questions:
Q1: What is the maximum load capacity of this 5mm thickness grating?
A: Load capacity depends on the bearing bar height and span. For example, with 30mm height and 600mm support span, it can handle a uniformly distributed load of approximately 4 kN/m². For specific applications, we can provide load charts and recommend the optimal bar height.
Q2: Can I order custom sizes or cut panels?
A: Absolutely. We offer custom lengths, widths, and cutouts for pipes or columns. Just send us a drawing or specify dimensions, and we will fabricate accordingly.
Q3: Is the serrated surface safe for barefoot walking?
A: This grating is designed for industrial use with safety shoes. The serrations provide excellent grip for boot soles but may feel rough to bare skin. For light-duty applications, consider a smooth surface version.
Q4: How does the galvanized coating hold up in marine environments?
A: Hot dip galvanizing offers good protection in coastal areas. For extreme marine conditions, we recommend a thicker coating (≥ 650 g/m²) or an additional epoxy paint layer. We can customize the zinc coating weight upon request.
Q5: What are the typical lead times?
A: Standard sizes (e.g., 1m x 6m) usually ship within 15–18 days. Custom orders may take 20–25 days, depending on complexity and quantity.
Q6: Do you provide installation accessories like clips or toe plates?
A: Yes, we supply saddle clips, bent angle borders, toe plates, and stair tread nosing as optional accessories. Please inquire for a complete accessory list.
Q7: What is the minimum order quantity (MOQ)?
A: Our MOQ is 50 square meters for standard sizes. For first-time trial orders, we can accept as low as 20 square meters to help you evaluate the quality.
Q8: How do I clean and maintain the grating?
A: Regular hosing with water or low-pressure washing is sufficient. Avoid using abrasive cleaners that may scratch the galvanized finish. Inspect periodically for any damage and touch up with cold galvanizing spray if needed.
