Hello, we are Hengshui Ruibin New Materials LLC, a professional manufacturer established in 2019 with a factory size of 1,000-3,000 square meters and an annual export value between US$2.5 Million and US$5 Million. Our team of 101-200 dedicated employees serves markets across North America, South America, Europe, Southeast Asia, Africa, Oceania, the Middle East, and more. The Stainless Steel Bar Grating 304L 40x5mm with 30x100mm Mesh is one of our flagship products, engineered specifically for high-performance drainage covers. It combines the corrosion resistance of 304L stainless steel with precision-manufactured dimensions to ensure long-lasting durability and efficient water flow. Whether for industrial flooring, trench covers, or municipal drainage systems, this grating delivers reliable strength and easy maintenance, making it a trusted choice for engineers and contractors worldwide.
Our product features a robust construction using 304L stainless steel, a low-carbon variant that offers excellent weldability and resistance to intergranular corrosion. The 40x5mm bearing bars and 30x100mm mesh pattern are designed to provide optimal load distribution while allowing water and debris to pass through effectively. Below is a summary of key specifications:
| Parameter | Value |
|---|---|
| Material | Stainless Steel 304L |
| Bearing Bar Dimensions | 40mm (height) x 5mm (thickness) |
| Mesh Opening (Clear Span) | 30mm x 100mm |
| Surface Treatment | Mill Finish (pickled & passivated available upon request) |
| Standard Panel Size | Customizable (common: 1m x 6m) |
| Load Capacity | Varies by support spacing; technical data available upon request |
Beyond the standard dimensions, we offer extensive customization options to match specific project requirements. The grating can be supplied with serrated bars for enhanced slip resistance, and surface treatments such as electropolishing or passivation can be applied to improve corrosion resistance in aggressive environments. Each panel is manufactured using advanced welding techniques, ensuring consistent quality and dimensional accuracy.
Key advantages of choosing our 304L Stainless Steel Bar Grating include:
- Superior corrosion resistance – ideal for drainage applications exposed to moisture, chemicals, or saltwater.
- High strength-to-weight ratio – the 40x5mm bars provide ample load-bearing capacity without excessive weight.
- Efficient drainage – the 30x100mm open area allows water and small debris to pass freely, reducing flooding risk.
- Low maintenance – stainless steel does not require painting or coating; simple cleaning restores appearance.
- Easy installation – panels can be cut, welded, or clamped on-site; anchoring options available.
- Custom sizes – we can produce non-standard widths, lengths, or mesh configurations to fit your exact needs.
- Eco-friendly – 100% recyclable material supports sustainable construction practices.
Our manufacturing process follows strict quality control procedures. We begin with certified 304L stainless steel coils and bars, then cut, weld, and finish each panel using automated and manual inspection steps. Every batch is tested for dimensional accuracy, weld integrity, and surface quality before packaging. With annual exports exceeding US$2.5 Million and a global customer base, we have built a reputation for reliability and on-time delivery.
We also provide free professional advice on product selection, load calculations, and installation methods. Our experienced engineering team can help you determine the ideal bearing bar spacing and support structure for your specific load requirements. Additionally, we offer sample panels for testing before bulk orders, ensuring you get exactly what you need.
Trusted by clients in over 20 countries, our stainless steel grating has been used in municipal drainage projects, food processing plants, marine docks, and heavy industrial facilities. Contact us today to discuss your project requirements and receive a competitive quotation.
Frequently Asked Questions
A: 304L has a lower carbon content (max 0.03%) compared to 304 (max 0.08%). This reduces the risk of carbide precipitation during welding, making 304L more suitable for welded assemblies and applications where post-weld corrosion resistance is critical. For drainage covers exposed to harsh conditions, 304L is often the preferred choice.
A: Yes, we can calculate load capacity based on your support spacing, span length, and required safety factor. Please contact our technical team with your project details; we will provide a free engineering report.
A: The standard flat bars offer moderate slip resistance. For high-traffic areas, we recommend serrated bars (toothed surface) or adding a grit-top coating. Both options are available on request.
A: Installation methods include: (a) welding to a steel frame, (b) using hold-down clips or anchor bolts, (c) embedding into concrete with pre-set inserts. We offer installation accessories and can provide a detailed guide.
A: Absolutely. We can produce panels in any length up to 7 meters, any width up to 2 meters, and adjust both bar spacing and cross bar spacing. Minimum order quantity may apply for non-standard sizes.
A: Panels are bundled with steel strapping, interleaved with protective materials to prevent scratches, and packed in wooden crates or steel pallets for container shipment. Lifting eyes can be added for easier handling.
A: Standard production lead time is 15-25 working days after order confirmation and deposit. Large or urgent orders can be expedited upon request.
A: We can provide material test certificates (MTC) from the steel mill, as well as our in-house quality inspection reports. Third-party testing (e.g., SGS, BV) is available at an additional cost.
