Anping Xinye Metal Wire Mesh Products Co., Ltd, located in the hardware industry hub of Hengshui, Hebei, China, has been a trusted manufacturer of high-quality steel gratings for over a decade. Our Steel Grating Welded Type Hot Dipped Galvanized 30x3mm is engineered to deliver exceptional strength and durability for demanding industrial environments. With a load capacity of 3 kN/m² and a 12-month warranty, this product is the ideal choice for heavy-duty flooring, walkways, and platforms where safety and longevity are paramount.
The welded construction ensures a rigid, slip-resistant surface that can withstand constant foot traffic, vehicle loads, and impact. The hot-dipped galvanized coating provides superior corrosion resistance, making it suitable for both indoor and outdoor applications, including chemical plants, refineries, power stations, and wastewater treatment facilities. Each panel is precisely fabricated using 30mm wide × 3mm thick bearing bars, offering an optimal balance of strength and weight.
Key Features & Benefits
- Welded Construction: Each intersection of bearing bar and cross bar is fused under high pressure and heat, creating a monolithic structure that resists loosening and deformation.
- Hot-Dipped Galvanized Finish: The entire grating is immersed in molten zinc, forming a thick, metallurgically bonded coating that protects against rust, chemicals, and UV radiation. Average coating thickness: ≥85 μm per ASTM A123.
- 30x3mm Bearing Bars: The 30mm width provides a wide load-bearing surface, while the 3mm thickness ensures rigidity without excessive weight. Suitable for medium-duty applications up to 3 kN/m².
- High Load Capacity: Tested and rated at 3 kN/m², equivalent to a uniformly distributed load of 300 kg per square meter, meeting typical industrial floor loading requirements.
- 12-Month Warranty: We stand behind the quality of our product. Coverage includes manufacturing defects and galvanizing integrity under normal use.
- Customizable Dimensions: Panels can be cut to your exact size, hole patterns, or serrated surfaces upon request. Available in various mesh sizes (e.g., 30×100mm, 40×100mm).
- Easy Installation: Lightweight yet strong, standard panels are easy to handle with forklifts or cranes. Can be welded, clipped, or bolted to supporting structures.

Frequently Asked Questions
-
Q: What is the maximum span for this grating under a load of 3 kN/m²?
A: The maximum unsupported span depends on the bearing bar pitch and cross bar spacing. For a standard 30×100mm mesh, the recommended span is up to 800 mm for a deflection of L/200. Contact our engineers for a span calculation based on your specific layout. -
Q: Is the hot-dipped galvanized coating suitable for outdoor use in coastal areas?
A: Yes, the galvanized coating provides excellent corrosion resistance in marine environments. However, for extremely aggressive conditions, we recommend a thicker coating or additional protective paint. Our galvanizing meets ASTM A123 standards. -
Q: Can I order this grating with serrated bearing bars for slip resistance?
A: Absolutely. Serrated (toothed) bearing bars are available as an option. They provide enhanced grip in oily or wet conditions. Please specify when placing your order. -
Q: How is the load capacity of 3 kN/m² tested?
A: We perform uniform load testing using a hydraulic press and digital gauges. The panel is supported on all four sides, and the load is applied gradually until the specified deflection is reached. All test results are documented and traceable. -
Q: Do you offer custom sizes and shapes?
A: Yes, we can cut any panel to your exact dimensions, including notches, holes, or curved edges. Minimum order quantity may apply for custom shapes. Please provide a drawing or CAD file for a quotation. -
Q: What is the typical lead time for standard panels?
A: For standard sizes and quantities under 100 m², lead time is 10–15 working days. For larger orders or custom specifications, lead time is 20–30 working days. Expedited shipping is available upon request. -
Q: Does the warranty cover damage during installation?
A: The 12-month warranty covers manufacturing defects in material and workmanship only. Installation damage, misuse, or modifications are not covered. We provide installation guidelines to help avoid common issues. -
Q: Can I get a sample before placing a bulk order?
A: Yes, we offer small samples (e.g., 300×300 mm) for quality evaluation. The sample cost is deducted from your first full order. Contact our sales team to arrange a sample.
