Since 1998, Anping County Boli Hardware Wiremesh Products Factory has been a trusted manufacturer of high-quality steel gratings, exporting to over 15 global markets with an annual export value of US$5-10 million. Our Carbon Steel Bar Grating with 40x5mm bearing bars and 10mm spacing is engineered specifically for floor drainage applications, combining robust load-bearing capacity with efficient water flow. This welded steel grating offers a durable, slip-resistant surface that meets the demanding needs of industrial, commercial, and municipal drainage systems.
Each panel is precision-welded from hot-rolled carbon steel bars, ensuring consistent bar spacing and structural integrity. The 40mm bar height and 5mm thickness provide excellent rigidity, while the 10mm clear spacing allows debris and water to pass through freely without clogging. Whether used in trench drains, platform walkways, or heavy-duty flooring, this grating delivers long-lasting performance under high traffic and harsh conditions.

Frequently Asked Questions
1. What is the maximum panel size you can produce?
We can customize panels up to 2 meters in width and 6 meters in length. Larger sizes may be available upon request with additional support bars.
2. Can this grating be used for heavy vehicle traffic?
The 40x5mm bar grating is suitable for light to medium vehicle loads (e.g., passenger cars, forklifts). For heavy truck traffic, we recommend thicker bars or closer spacing. Please provide load requirements for a customized design.
3. What surface treatment options do you offer?
Standard option is plain mill finish (oiled to prevent rust during transit). Hot-dip galvanizing is available as an optional upgrade for enhanced corrosion resistance. We can also apply epoxy coating or painting upon request.
4. How is the grating packaged for export?
Gratings are bundled with steel strapping, separated by wooden spacers, and wrapped in waterproof material. Panels can be stacked or palletized based on quantity. We ensure secure packaging to prevent damage during sea freight.
5. Do you provide sample panels for testing?
Yes, we offer small samples (e.g., 300x300mm) for evaluation. Sample cost and shipping are negotiable. Contact us with your requirements.
6. What is the typical lead time for an order?
For standard sizes, lead time is 15-20 days after deposit. Custom orders may require 25-30 days depending on complexity and quantity. We can expedite urgent orders with prior arrangement.
7. Are there any restrictions on the use of plain carbon steel in outdoor environments?
Plain carbon steel will rust when exposed to moisture and oxygen. For outdoor or wet applications, we strongly recommend hot-dip galvanized finish to prevent corrosion and extend service life. Indoor use with plain finish is acceptable if properly maintained.
8. Can you provide load-bearing calculation data?
Yes, we can supply deflection and load capacity charts based on span, bar size, and spacing. Our engineering team will assist in selecting the appropriate grating for your project. Please provide the span and intended load.
