Steel bar grating has two surface type: serrated surface and smooth surface. Serrated steel grating is made of serrated steel bars, which can be low carbon steel bars, aluminum steel bars and stainless steel bars. The serrated steel bars are welded, press-locked, swage-locked or connected by rivets to form different types of steel grating.Maximize slip resistance in oily or wet conditions with our heavy-duty serrated bar steel grating.

For project engineers, safety officers, and procurement teams, serrated grating is not merely an optional upgrade from plain surface grating. In many jurisdictions and industry sectors, slip-resistant flooring is a regulatory or contractual requirement for pedestrian walkways, stair treads, offshore decks, and industrial platforms. Specifying the correct serrated grating — with the right bar size, spacing, material, and surface treatment — directly impacts worker safety, compliance, and long-term maintenance cost.

At Hebei Canri Wire Mesh Co., Ltd., we manufacture premium serrated bar steel grating and serrated steel grating designed specifically for maximum slip resistance in challenging conditions. Unlike smooth bar grating, our slip resistant serrated steel grating features notched bearing bars that provide superior traction even when wet, oily, or covered in debris — making it the go-to choice for safety-critical industrial and infrastructure projects.

1. Anti-slip. Serrated edges significantly reduce slip hazards, which can be used in the wet and slippy places,ideal for ramps, platforms, and industrial walkways,

2. Corrosion resistance. Galvanized surface treatment supplies good corrosion resistance performance, which ensure the long service life.

3. Acid and alkali resistance. Stainless steel serrated steel grating has excellent chemical stability, which can be used in the salty and other chemical corrosive environments.

4. Protect safe. The serrated surface can protect pedestrian from slipping down and secure the safe of pedestrians.

5. Customizable – Available in various serration patterns (one-sided or two-sided), bar spacing, and thicknesses to meet project specs.  

6. Elegant and stylish. Clean lines and a silver finish align with modern aesthetics.

7. High strength. Significantly superior strength and toughness compared to cast iron. Suitable for large-span, heavy-load applications such as docks and airports.

8. Anti-theft design. The grating panel is hinged to the frame for secure, reliable, and easy access.

9. Cost-saving investment. Large span capacity. Compared to cast iron products, it suffers less weight loss under heavy loads. Using cast iron eliminates the risk costs associated with theft or crushing damage.

10. Optimal drainage performance. With an 83.3% permeable area, it offers over twice the drainage capacity of cast iron products.

Offshore Oil and Gas Platforms

Helideck perimeter flooring, walkways between modules, stair towers, and access platforms. The combination of saltwater exposure and wet, oily conditions makes 316L stainless steel serrated grating the standard specification. Serrated surface is mandatory for safety in these environments.

Industrial Plants and Refineries

Process unit walkways, pump platforms, pipe rack access floors, and maintenance platforms where hydrocarbon spills, water, and chemical exposure are routine. Galvanized carbon steel serrated grating is common for most areas; stainless steel for sour service or acid handling areas.

Food and Beverage Facilities

Production floor walkways, drainage trench covers, mezzanine platforms, and stair treads in areas subject to regular washdown with water, caustic solutions, or food byproducts. Stainless steel 304 or 316L with pickling and passivation is standard.

Water and Wastewater Treatment

Filter gallery walkways, aeration tank access platforms, chemical dosing area flooring, and trench drain covers exposed to moisture, chlorine, and hydrogen sulfide. Galvanized or stainless steel depending on corrosion severity.

Ports, Docks and Maritime Infrastructure

Berth decking, container yard access roads, pilot walkways, and fender system access platforms exposed to tidal splash, rain, and cargo residue.

Municipal and Landscape

Pedestrian bridge decking, park walkways, tree grates, and urban plaza surfaces where public safety in wet weather is a priority. Press-locked serrated grating with a specific finish may be specified for architectural projects.

Power Plants and Energy Infrastructure

Boiler house access platforms, turbine hall walkways, cooling tower decking, and transformer yard flooring where safety, drainage, and ventilation are all required simultaneously.

Mining and Heavy Industry

Crusher plant walkways, conveyor gallery flooring, loading dock platforms, and haul road access structures where mud, water, and abrasive materials contact the walking surface.
