Advantages & Customer Benefits
- Superior Corrosion Protection: Hot dip galvanizing ensures a tough, sacrificial zinc coating that protects the steel for decades, reducing maintenance costs.
- High Strength-to-Weight Ratio: The 25×5 mm bearing bars provide excellent load-bearing capacity while keeping the grating lightweight and easy to transport and install.
- Open Design for Drainage & Ventilation: The grid pattern allows water, debris, and light to pass through, making it ideal for outdoor platforms, drainage covers, and ventilation grilles.
- Slip Resistance Options: Choose plain bearing bars for general use or serrated bars for maximum traction in slippery environments – perfect for petrochemical plants, food processing areas, and marine applications.
- Easy Installation: Panels can be cut on-site with an angle grinder, and they can be welded or clipped to supporting structures. Our factory can pre-drill holes for bolting if required.
- Long Service Life: With proper maintenance, hot dip galvanized grating can last 20-30 years even in outdoor coastal environments, saving you replacement costs.

Frequently Asked Questions (FAQ)
-
Q: What is the load capacity of this grating?
A: The standard load capacity is 1000 kg/m² under uniform load, based on the 25×5 mm bearing bars and typical spacing. For specific spans and concentrated loads, please consult our engineering team for a detailed calculation. -
Q: Can I get different bar sizes or spacing?
A: Yes, we offer customization. Common bearing bar sizes range from 20×3 mm to 50×5 mm, and center-to-center spacing can be adjusted from 20 mm to 60 mm. Please provide your requirements. -
Q: Is the grating rust-proof?
