Serrated Welding Steel Grating, 25x3mm Bars, 30x50mm Mesh, Hot Dip Galvanized, Anti-Slip for Steel Floor Projects
Product Spotlights
Welcome to Anping County Boli Hardware Wiremesh Products Factory, a trusted manufacturer since 1998. We proudly present our Serrated Welding Steel Grating – a premium solution for steel floor projects requiring maximum traction and durability. With 25x3mm bearing bars and a 30x50mm mesh pattern, hot dip galvanized for corrosion resistance, this grating is engineered to provide safe, long-lasting walkways in industrial environments.
Our product combines the strength of welded steel construction with a serrated surface on each bearing bar, ensuring superior anti-slip performance even in oily or wet conditions. Whether you need heavy-duty flooring for chemical plants, oil rigs, or commercial catwalks, this grating meets rigorous safety standards while offering excellent load-bearing capacity.
Key Features & Technical Specifications
- Serrated Surface: Each bearing bar features a raised serration pattern (teeth) that provides exceptional slip resistance – ideal for areas with frequent foot traffic or machinery movement.
- Hot Dip Galvanized (HDG): The entire grating is immersed in molten zinc, creating a thick, uniform coating that protects against rust, chemicals, and UV exposure. Average coating thickness: 85-100 microns per ASTM A123.
- Welded Construction: Cross bars are resistance-welded to bearing bars at every intersection, forming a rigid, monolithic structure that distributes loads evenly and resists twisting.
- Bearing Bar Dimensions: 25mm width x 3mm thickness – a balance of strength and weight, suitable for light to medium industrial loads.
- Mesh Opening: 30mm (center-to-center of bearing bars) x 50mm (center-to-center of cross bars) – allows debris, water, and light to pass through while maintaining a safe walking surface.
- Anti-Slip Performance: Tested according to ASTM F1679 (standard test method for surface friction) – the serrated pattern significantly increases the coefficient of friction compared to smooth bars.
- Customizable Options: Panel sizes, bar spacing, serration pitch, and cut-outs are available upon request. We can also supply matching clips, fasteners, and perimeter trims.
Typical Applications
- Steel floor platforms, mezzanines, and walkways
- Catwalks in refineries, chemical plants, and power stations
- Drainage covers, trench grates, and stair treads
- Loading docks, ramps, and vehicle access areas
- Offshore platforms and marine structures

Benefits to Your Project:
- Reduced accident risk – the serrated surface provides reliable traction even when wet, greasy, or covered with debris.
- Low maintenance – hot dip galvanizing eliminates the need for painting or frequent coating repairs, saving time and money.
- Easy installation – panels are pre-cut to size and can be simply bolted or welded into place; we offer custom cut-outs for pipes or columns.
- Long service life – with proper design, HDG steel grating can last 20–30 years in most industrial environments.
- Cost-effective – compared to stainless steel or aluminum grating, our galvanized steel option offers similar performance at a fraction of the cost.

Frequently Asked Questions
-
Q: What is the difference between serrated and plain grating?
A: Serrated grating has raised teeth on the bearing bars, providing significantly better slip resistance. Plain grating is smooth and may be slippery in wet or oily conditions. Serrated is recommended for areas where safety is critical. -
Q: Can I order custom sizes or cut-outs?
A: Yes, we offer custom panel sizes, bar spacing, and cut-outs for pipes, columns, or stairs. Please provide a drawing or specifications, and we will produce accordingly. -
Q: How long does the hot dip galvanized coating last?
A: In most industrial environments, HDG coatings can last 20–30 years before requiring maintenance. The actual lifespan depends on exposure conditions (humidity, chemical exposure, etc.). -
Q: What is the load capacity of your 25x3mm grating?
A: For a typical 30x50mm mesh, the uniform load capacity is approximately 4 kN/m² with a safety factor of 2.5. For specific applications, we can provide engineering calculations based on your span and loading requirements. -
Q: Do you provide installation accessories like clips or bolts?
A: Yes, we offer matching galvanized clips, saddle clips, and bolts for easy attachment to support beams. Please inquire when ordering. -
Q: Is your product certified for use in oil and gas plants?
A: While we do not hold specific certifications (e.g., ISO, CE) unless requested, our grating meets general industry standards for anti-slip and corrosion resistance. Many customers in refineries and chemical plants have successfully used our products. We can provide material test certificates if required. -
Q: What is the minimum order quantity?
A: For standard sizes, MOQ is 10 square meters. For custom sizes, MOQ may be higher depending on complexity. Contact us for details. -
Q: How long does shipment take?
A: For standard products, production takes 7–10 working days; shipping time depends on destination. We work with reliable freight forwarders to ensure timely delivery.
