Anping County Boli Hardware Wiremesh Products Factory, established in 1998, proudly presents our Hot Dipped Galvanized Bar Grating 40x5mm with 100x100mm Mesh for Walkway. With over two decades of manufacturing expertise and annual export value exceeding US$5 million, we are committed to delivering high-quality, durable grating solutions for industrial and commercial walkways. This product combines superior load-bearing capacity with excellent corrosion resistance, making it an ideal choice for heavy-duty applications where safety and longevity are paramount.
Our bar grating is engineered using precision manufacturing processes, ensuring consistent dimensions and reliable performance. The hot-dipped galvanized coating provides robust protection against rust and environmental wear, while the 40x5mm bearing bars and 100x100mm mesh spacing offer optimal strength and anti-slip properties. Whether used in petrochemical plants, wastewater treatment facilities, or public walkways, this grating ensures safe footing and long service life.
Below, we detail the key specifications, features, and benefits of this product to help you make an informed purchasing decision.
Key Features & Benefits
- Superior Load Capacity: 40mm x 5mm bearing bars provide high strength-to-weight ratio, suitable for pedestrian and light vehicle traffic.
- Hot Dipped Galvanized Finish: Conforms to ASTM A123 standards (available upon request), offering excellent corrosion resistance for outdoor and harsh environments.
- 100x100mm Mesh Opening: Balanced design allows efficient drainage and light penetration while preventing small objects from falling through.
- Anti-Slip Surface: Twisted cross bars create a textured surface that enhances traction, reducing slip risks in wet or oily conditions.
- Easy Installation: Lightweight yet sturdy, panels can be cut, welded, or fastened with standard hardware on site.
- Low Maintenance: Galvanized coating minimizes the need for frequent painting or repairs, lowering lifecycle costs.
- Customizable Options: Available in various lengths, widths, and edge treatments (banding, serrated bars) to meet specific project requirements.

Detailed Product Description
The 40x5mm bar grating is a popular choice for walkway applications due to its balanced combination of strength, weight, and cost-effectiveness. The bearing bars are 40mm high and 5mm thick, providing a substantial moment of inertia that resists bending under load. The 100x100mm mesh spacing is wide enough to allow debris, water, and snow to pass through, reducing accumulation and slip hazards, yet narrow enough to prevent most tools, heels, or small objects from falling through.
The hot-dipped galvanizing process involves immersing the entire grating panel in molten zinc, creating a metallurgically bonded coating that protects the steel substrate even on edges, corners, and inside joints. This coating can withstand decades of exposure to rain, humidity, chemicals, and UV radiation without peeling or flaking, making it ideal for outdoor walkways, platforms, and trench covers.
Our manufacturing facility in Hengshui, Hebei, China, is equipped with advanced automatic welding machines and galvanizing lines, ensuring consistent quality and quick turnaround. Every panel undergoes strict dimensional inspection and coating thickness measurement before shipment. We can also provide serrated bearing bars for enhanced anti-slip performance, or add banding (flat bar around edges) for extra rigidity.
Typical applications include:
- Industrial walkways and catwalks
- Platforms and mezzanine floors
- Drainage covers and trench grates
- Stair treads (with additional nosing)
- Vehicle access ramps (light duty)
- Water treatment plant grating
Compared to other surface treatments like painted or electro-galvanized, hot-dipped galvanized offers superior durability and lower maintenance over the product's lifespan. It is a cost-effective solution for projects requiring long-term corrosion protection without frequent recoating.

Frequently Asked Questions
1. What is the maximum unsupported span for this grating?
The 40x5mm bar grating with 100x100mm mesh can typically span up to 800mm under light pedestrian traffic, and up to 600mm under heavier loads. For precise span ratings, please consult our engineering team with your specific load requirements.
2. Can I get this grating with serrated bars for anti-slip?
Yes, serrated bearing bars are available as an option. Serrations increase surface friction and are recommended for areas that are frequently wet, oily, or dusty. Please specify when ordering.
3. How is the hot-dipped galvanized coating applied?
The grating panels are cleaned, pickled, fluxed, and then immersed in a bath of molten zinc at approximately 450°C. The zinc reacts with the steel to form a durable, corrosion-resistant alloy layer. Our process follows standard industry practices (e.g., ASTM A123).
4. What is the minimum order quantity?
We typically require a minimum order of 50 square meters for standard panels. For custom sizes or special requirements, the MOQ may vary. Please contact us for details.
5. Can you cut the grating to non-standard sizes?
Absolutely. We can cut panels to your exact length and width within a tolerance of ±2mm. We also offer banding (flat bar edge) for additional strength when cut edges are exposed.
6. How long does delivery take?
For standard sizes, production takes 7-10 days after order confirmation. Shipping time depends on the destination port and method (sea freight typically 20-35 days). We can also arrange express delivery for small samples.
7. Do you provide load capacity charts?
Yes, we can provide load tables based on standard formulas (e.g., NAAMM MBG 534). Please request the specific load rating for your application, including live load, dead load, and deflection limits.
8. What payment terms do you accept?
We accept T/T (30% deposit, 70% before shipment), L/C at sight, and for long-term partners, we can discuss other terms. For new customers, we recommend using PayPal or trade assurance for small orders.
