Welcome to Anping County Boli Hardware Wiremesh Products Factory, a trusted manufacturer since 1998 with an annual export value of US$5-10 million, serving markets across North America, South America, Europe, Asia, and Oceania. Our Hot Dip Galvanized Welding Steel Grating with 25x5mm bearing bars is engineered to meet the demanding requirements of steel floor projects, offering exceptional durability, slip resistance, and long-term corrosion protection. This product represents the perfect balance of strength and cost-effectiveness, backed by decades of manufacturing expertise and rigorous quality control.
Product Overview
Our welded steel grating is manufactured from high-quality ASTM A36 steel, ensuring consistent mechanical properties and reliable performance. The hot dip galvanized surface treatment provides a uniform zinc coating that protects against rust and environmental wear, making it ideal for industrial flooring, platforms, walkways, and mezzanines. The 25x5mm bearing bar size offers excellent load-bearing capacity while maintaining a lightweight structure for easy installation.
Key Features & Benefits
- High Strength-to-Weight Ratio: The 25x5mm bearing bars, combined with welded cross bars, deliver superior structural integrity without unnecessary weight, reducing steel costs and supporting loads.
- Hot Dip Galvanized Protection: The zinc coating meets ASTM A123 standards (optional) and provides decades of maintenance-free service, even in harsh environments.
- Slip-Resistant Surface: The open grid design allows debris, water, and snow to fall through, minimizing slip hazards and improving safety.
- Customizable Dimensions: Bar spacing, cross bar pitch, panel size, and overall dimensions can be tailored to your specific project requirements.
- Easy Installation: Lightweight panels can be cut, welded, or clamped on-site, reducing labor time and costs.
- Low Maintenance: The galvanized finish eliminates the need for painting or regular maintenance, saving long-term operational expenses.

Frequently Asked Questions
Q1: What is the maximum load capacity of this 25x5mm grating?
A: Load capacity depends on bar spacing, span, and support conditions. For a typical 30mm spacing with 1m span, the safe load can exceed 400 kg/m². We provide detailed load tables upon request for your specific configuration.
Q2: Can I get the grating in other sizes besides 25x5mm?
A: Yes, we offer a wide range of bearing bar sizes from 20x3mm to 50x5mm. Custom sizes are available with minimum order quantities. Please contact us with your requirements.
Q3: How long does the hot dip galvanized coating last?
A: In typical industrial environments, the zinc coating thickness of 70-85µm provides corrosion protection for 20-30 years before any maintenance is needed. Actual lifespan depends on exposure conditions.
Q4: Do you provide cut-to-size panels or only standard sheets?
A: We can cut panels to your exact dimensions, including notches, holes, and curved edges. Custom fabrication is available with a small surcharge.
Q5: What is the lead time for an order?
A: For standard sizes, lead time is 15-20 working days after order confirmation. Custom orders may take 25-30 working days. Rush orders can be arranged for an additional fee.
Q6: Is the grating suitable for outdoor use?
A: Yes, the hot dip galvanized finish makes it highly resistant to rain, snow, and UV exposure. It is commonly used for outdoor platforms, catwalks, and drainage covers.
Q7: Do you offer any certifications or test reports?
A: We can provide material test certificates for the steel and zinc coating thickness reports upon request. Third-party inspections are also welcome.
Q8: What is the minimum order quantity (MOQ)?
