Anping County Boli Hardware Wiremesh Products Factory (established 1998) proudly presents our premium Carbon Steel Bar Grating designed specifically for industrial platform floors. Our welded steel grating features 25x3mm bearing bars with 50x50mm openings, delivering exceptional strength, durability, and slip resistance for demanding environments. With over two decades of manufacturing expertise and an annual export value of US$5–10 million, Boli provides reliable grating solutions trusted by clients across North America, Europe, Southeast Asia, and beyond.
Product Overview & Key Features
Our carbon steel bar grating is manufactured using advanced resistance welding technology, ensuring each joint is forged under high pressure and temperature for uniform strength. The 25mm wide by 3mm thick bearing bars provide a high load-to-weight ratio, while the 50x50mm square openings allow efficient drainage, light transmission, and ventilation. Ideal for heavy-duty industrial platforms, catwalks, mezzanines, and trench covers, this grating meets the rigorous demands of factories, warehouses, refineries, and processing plants.
- High Load Capacity – 25x3mm bars offer superior strength for heavy machinery and foot traffic.
- Slip Resistance – Serrated surfaces and open grid design reduce slipping risks in wet or oily conditions.
- Easy Maintenance – Openings allow debris and liquids to pass through, preventing accumulation.
- Customizable Dimensions – Panels can be cut to exact size, with optional surface treatments (plain, hot dip galvanized, or painted).
- Cost-Effective – Compared to solid steel plates, bar grating reduces material cost while maintaining structural integrity.
- Versatile Applications – Suitable for platform floors, walkways, stair treads, machine guards, and drainage covers.

Detailed Advantages & Customer Benefits
Durability and Longevity – Our carbon steel grating is manufactured to withstand harsh industrial environments. The welded construction eliminates loose joints, and the optional hot dip galvanized coating provides excellent corrosion resistance, extending service life even in outdoor or chemical-prone areas.
Enhanced Safety – The open grid design allows light and air to pass through, reducing shadows and improving visibility. The slip-resistant surface (plain or serrated) helps prevent accidents in wet, greasy, or icy conditions. For platforms that require frequent cleaning, the openings allow easy wash-down without water pooling.
Cost Savings – Compared to solid steel plates, bar grating uses less material while delivering comparable structural strength. This reduces overall weight, lowering shipping costs and simplifying installation. The modular nature of grating also allows quick replacement of damaged sections without full panel removal.
Customization – We offer flexible panel dimensions, different bar sizes, and various surface finishes to meet your specific project requirements. Whether you need U-shaped end bands, mulch holes, or special cut-outs for pipes, our factory can fabricate to your drawings.
Global Logistics – With ports of shipment in Tianjin, Qingdao, Shanghai, and Foshan, we efficiently deliver to major markets worldwide. Our experienced team ensures proper packaging (steel pallets, slings, or crates) to protect grating during transit.

Frequently Asked Questions (FAQ)
-
Q: What is the maximum span for this grating under a 5 kN/m² load?
A: The maximum safe span depends on the bearing bar size and support conditions. For 25×3mm bars with 50mm spacing, the typical unsupported span is around 800–1000 mm for a 5 kN/m² uniform load. We recommend sending your specific load and support details for a precise calculation.
-
Q: Can I get serrated bars for better slip resistance?
A: Yes, we offer serrated (toothed) bearing bars as an option. Serrated surfaces provide additional grip, especially in oily or wet environments. Please specify when ordering.
-
Q: What surface treatment do you recommend for outdoor use?
A: For outdoor applications, hot dip galvanized (HDG) coating is highly recommended. It provides excellent corrosion resistance against rain, humidity, and UV exposure. We also offer painted finishes (e.g., epoxy) for specific chemical resistance.
-
Q: How are the panels connected or installed?
A: Panels are typically welded to steel supports using fillet welds at the bearing bar intersections. Alternatively, they can be fastened with U-bolts, clips, or saddle clamps. We can provide custom end bands (angle bars) for easy bolting if required.
-
Q: What is the tolerance on panel dimensions?
A: Our standard manufacturing tolerance is ±2 mm on length and width, and ±1 mm on opening size. For tighter tolerances, please discuss with our engineering team.
-
Q: Do you offer samples for quality evaluation?
A: Yes, we can provide small samples (e.g., 300×300 mm) for testing. The sample cost is refundable upon bulk order. Please contact us to arrange.
-
Q: What is the minimum order quantity (MOQ)?
A: Our MOQ for standard carbon steel bar grating is 50 square meters. For customized sizes or special finishes, MOQ may vary. We welcome both large and small inquiries.
-
Q: How long does delivery take?
A: For standard sizes, production takes 15–20 working days after order confirmation. For custom orders, please allow 20–30 working days. Shipping time depends on the destination port (typically 15–40 days by sea).
