About Our Press-Locked Steel Bar Grating
Our company, Anping County Boli Hardware Wiremesh Products Factory, has been a trusted manufacturer of steel gratings and wire mesh products since 1998. With an annual export value exceeding US$5 million, we supply high-quality press-locked steel bar gratings to markets across North America, South America, Europe, Africa, and Asia. This Press-Locked Steel Bar Grating features 25x5mm flat bars with a 30x30mm pitch, offering exceptional strength, corrosion resistance, and reliable performance for industrial flooring, walkways, and trench covers. Every panel comes with a Mill Test Report to guarantee material integrity.
Product Features & Technical Specifications
- Press-Locked Construction – No welding involved, ensuring a smooth, uniform structure with high load-bearing capacity. The mechanical locking process eliminates heat-affected zones, maintaining the bar’s original strength.
- Flat Bar Dimensions – 25mm width x 5mm thickness (available in other sizes upon request). The flat bar profile provides a larger bearing surface, ideal for heavy pedestrian and light vehicular traffic.
- Pitch Design – 30mm center-to-center spacing between bearing bars and 30mm spacing between cross bars. This balanced grid offers excellent load distribution, slip resistance, and ventilation.
- Material & Surface Treatment – Made from high-quality carbon steel (Q235, SS400, or equivalent). Optional surface treatments include hot-dip galvanizing, powder coating, or plain black finish. Galvanized grating offers superior corrosion resistance for outdoor or harsh environments.
- Mill Test Report Included – Each shipment comes with a certified mill test report verifying the chemical composition and mechanical properties of the steel. This ensures full traceability and compliance with international standards.
- Customizable Dimensions – Panel length, width, and flat bar spacing can be tailored to your project requirements. We also offer cut-to-size, notching, and banding options.

Advantages for Your Application
- High Load Capacity – The 25x5mm flat bars offer a generous moment of inertia, allowing the grating to support heavy loads while minimizing deflection. Ideal for industrial walkways, platforms, and mezzanines.
- Slip Resistance – The flat bar surface, combined with the 30mm grid pattern, provides excellent traction even in wet or oily conditions. Additional serrated surfaces are available upon request.
- Easy Installation – Press-locked grating panels are lightweight yet strong, and can be cut on-site without special tools. They can be bolted, welded, or clipped into place.
- Cost-Effective – Compared to welded gratings, press-locked gratings have a lower production cost because no welding is required. The savings are passed on to you without compromising quality.
- Versatile – Suitable for a wide range of industries: oil & gas, chemical plants, power plants, water treatment facilities, mining, commercial buildings, and more.

Frequently Asked Questions
-
Q: What is the maximum load capacity of this grating?
A: The load capacity depends on the span, support configuration, and load type. For a typical 1m span, the 25x5mm flat bar (30x30mm pitch) can support up to approximately 4 kN/m² uniformly distributed load. Please provide your specific span and loading requirements for a detailed calculation. -
Q: Can the grating be used outdoors?
A: Yes, but we recommend hot-dip galvanized surface treatment for outdoor applications to prevent rust. The galvanized coating offers excellent corrosion resistance in most environments. -
Q: Is the Mill Test Report included for every batch?
A: Yes, we provide a Mill Test Report (MTR) for each batch of steel used, confirming chemical composition and mechanical properties. You can request a copy before shipment. -
Q: Can you customize the panel size or bar spacing?
A: Absolutely. We can manufacture panels with different bearing bar sizes, spacing, and overall dimensions. Minimum order quantity applies for custom sizes – please consult our sales team. -
Q: What is the lead time for standard and custom orders?
A: For standard sizes (e.g., 1m x 3m panels), lead time is about 15–20 working days after deposit. Custom orders typically take 20–30 working days depending on complexity. -
Q: Do you provide samples? Is there a cost?
A: Yes, we can provide small samples (e.g., 200mm x 200mm) for evaluation. The sample is free, but you cover the shipping cost. Larger samples may be charged. -
Q: How is the grating packaged for export?
A: Panels are bundled with steel strapping, wrapped in waterproof paper or plastic, and then packed in wooden crates or pallets for sea freight. We ensure the packaging is suitable for long-distance transport. -
Q: What payment terms do you accept?
A: We accept T/T (30% deposit, 70% before shipment) and L/C at sight. For long-term cooperation, other terms can be discussed.
