As a trusted manufacturer with over 25 years of experience, Anping County Boli Hardware Wiremesh Products Factory (established 1998) proudly presents our Carbon Steel Bar Grating 25x3mm, 30x30mm Openings, Serrated Surface for Slip Resistance. This product is engineered to meet industrial standards for heavy-duty applications, offering superior strength and safety. Our factory exports millions of dollars of grating annually to markets worldwide, including North America, Europe, and Southeast Asia, ensuring consistent quality and reliable supply.
The bar grating features a 25mm x 3mm bearing bar profile with a serrated surface, providing excellent slip resistance even in wet or oily conditions. The 30mm x 30mm square openings balance load capacity with efficient drainage and light passage. Whether for walkways, platforms, or trench covers, this product delivers long-lasting performance in demanding environments.
Key Features & Technical Specifications
- High Strength Carbon Steel: Made from Q235 or SS400 carbon steel, with optional hot-dip galvanizing for enhanced corrosion resistance.
- Serrated Surface: Each bearing bar has a serrated (toothed) top surface, which increases traction and prevents slipping – ideal for industrial walkways, catwalks, and platforms.
- Standard Opening Size: 30mm x 30mm center-to-center, suitable for pedestrian traffic and light machinery areas.
- Heavy Duty Construction: Bearing bar thickness of 3mm and height of 25mm, combined with cross bars (typically 5x5mm or 6x6mm) welded at every 50mm or 100mm pitch for rigidity.
- Easy Installation: Pre-cut panels or custom sizes available; can be bolted, welded, or fixed with clips.
- Low Maintenance: Galvanized finish requires minimal upkeep; painted options available for specific environments.
- Versatile Applications: Used in factories, warehouses, power plants, water treatment plants, and outdoor drainage systems.

Frequently Asked Questions
-
What is the load capacity of this grating?
Load capacity depends on the span and bearing bar size. For a 25x3mm bar with 30mm openings, typical safe working load for pedestrian traffic is around 2-3 kN/m² over a 1m span. For heavy machinery, we recommend larger bars or closer spacing. Please provide your span and load requirements for a detailed calculation. -
Is the serrated surface standard on both sides?
The serration is typically applied only on the top surface of the bearing bars. If you require serrations on both sides (e.g., for grating used in inverted positions), please inform us for custom production. -
Can I get this grating hot-dip galvanized?
Yes, hot-dip galvanizing is available as an option. This finish provides excellent corrosion resistance and is recommended for outdoor or humid environments. The cost will be slightly higher than bare steel. -
What are the standard panel sizes?
Standard panels are 6m x 1m, but we can cut to any length and width up to 6m x 1.2m. Custom sizes are welcome; please specify your exact dimensions. -
How is the grating packaged for export?
Grating panels are bundled with steel strapping, palletized or packed in wooden crates for sea freight. We can also provide loose packing for small orders. Each bundle is labeled with dimensions and quantity. -
What is the lead time for a typical order?
For standard sizes, lead time is around 15-20 days after order confirmation. For custom sizes or special finishes, it may be 25-30 days. We work with efficient production schedules to meet your deadline. -
Do you provide samples before bulk order?
Yes, we can provide small samples (e.g., 300mm x 300mm) for evaluation. The sample cost is usually the freight charge, which can be deducted from the first bulk order. -
Can this grating be used for heavy vehicle traffic?
The 25x3mm bearing bar is designed for pedestrian and light to medium loads. For heavy vehicle traffic (e.g., forklifts, trucks), we recommend larger bearing bars such as 32x5mm or 40x5mm with smaller openings. Contact our engineers for a custom solution.
