As a leading manufacturer with over 20 years of experience, Anping County Boli Hardware Wiremesh Products Factory is proud to present our Hot Dip Galvanized Zinc Bar Grating specifically designed for demanding steel floor projects. With an annual export value exceeding US$5 million and a global footprint spanning North America, Europe, Southeast Asia, and beyond, we deliver industrial-grade grating solutions that combine superior load capacity, exceptional corrosion resistance, and cost-effective performance. Our 40x5mm bar, 30x100mm mesh grating offers a reliable 4kN/m² load capacity, making it the ideal choice for heavy-duty flooring applications in factories, warehouses, and commercial facilities.
This product is manufactured using high-quality steel bars that undergo a rigorous hot-dip galvanizing process, ensuring a uniform zinc coating that protects against rust, chemical exposure, and harsh weather conditions. The precise 30x100mm mesh pattern provides excellent drainage, anti-slip properties, and light transmission, while the 40x5mm bar dimensions deliver optimal strength-to-weight ratio. Whether you need pedestrian walkways, mezzanine floors, or industrial platforms, our bar grating meets the highest standards of safety and durability.

Frequently Asked Questions
-
Q: What is the maximum span for this grating under 4kN/m² load?
A: For a 40x5mm bar with 30x100mm mesh, the maximum recommended span is approximately 1.2 meters to maintain deflection under 1/200 of span. Please contact us for specific span calculations based on your project. -
Q: Can the grating be cut to non-standard sizes?
A: Yes, we offer custom cutting and fabrication. Panels can be trimmed to exact dimensions, and we can also add toe plates, banding, or cutouts for pipes and columns. -
Q: Is the hot-dip galvanized coating suitable for outdoor use?
A: Absolutely. The zinc coating provides excellent protection against UV, rain, snow, and saltwater. It is ideal for both indoor and outdoor environments, including coastal areas. -
Q: How does the load capacity tested?
A: Each batch is tested according to standard load test procedures (e.g., EN 1991-1-1) to ensure uniform load capacity of 4kN/m². We can provide test certificates upon request. -
Q: What surface options are available for anti-slip?
A: We offer both plain (flat) and serrated (toothed) bar tops. Serrated bars provide superior grip for wet or oily conditions, while plain bars are easier to clean. -
Q: What is the typical lead time for this product?
A: For standard sizes, lead time is 15–20 working days. Custom orders may require 25–30 days depending on complexity and quantity. We ship from Tianjin, Qingdao, Shanghai, or Foshan ports. -
Q: Do you provide installation accessories?
A: Yes, we supply matching clamping plates, bolts, saddle clips, and welding rods. We can also provide installation guidance or technical drawings. -
Q: What is the minimum order quantity?
A: MOQ is typically 50 m² for standard panels. For smaller quantities, please contact our sales team to discuss availability.
