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.

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.

Classification of serrated steel grating

The serrated steel grating has various different types, according to the different fabrications and materials, the serrated steel grating can be divided into different types. The different types can be applied in different applications and supply more choice for customers.

Fabrications of serrated steel grating

Welded serrated steel grating.

Welded serrated steel grating is produced by permanently joining serrated bearing bars and cross bars.

Swage-locked serrated steel grating.

Swage-locked serrated grating uses cross bars mechanically locked into the bearing bars. It may be selected for corrosion-resistant, lightweight, or architectural applications where stainless steel or aluminum is required.

Press-locked serrated steel grating.

Press-locked serrated steel grating uses mechanically interlocked bearing bars and cross bars. It provides a uniform grid pattern and is suitable for architectural, pedestrian, screening, and close-mesh applications where appearance and opening control are important.

Riveted serrated steel grating.

Riveted serrated steel grating is suitable for demanding applications involving vibration, impact, or heavy-duty loading. It can be considered for loading areas, industrial flooring, vehicle-access structures, and mining projects.

Materials of serrated steel grating

Low carbon serrated steel grating.

Aluminum serrated steel grating.

Stainless steel serrated steel grating.

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.

Serrated Grating vs. Plain Bar Grating

The correct surface should be selected according to the working environment, slip risk, maintenance conditions, and project safety requirements.

For standard industrial flooring in dry environments, see Flat Bar Steel Grating.

Surface and Finish Options

Surface profile and corrosion protection should be specified separately. Serrated bearing bars can be combined with different finishes according to the installation environment.

Black Steel Finish

Black steel grating is suitable for indoor applications, temporary installations, or projects where the customer will apply a separate protective coating after installation.

Hot-Dip Galvanized Finish

Hot-dip galvanized serrated grating is commonly specified for outdoor walkways, drainage covers, platforms, stair treads, and industrial facilities exposed to moisture or weather.

Painted or Powder-Coated Finish

Painted or powder-coated grating can be considered for indoor installations, color-coded safety zones, architectural projects, or locations where visual appearance is important. The coating system should be selected based on abrasion, UV exposure, and chemical conditions.

Stainless Steel Finish

Stainless steel serrated grating can be supplied for washdown, marine, food-processing, wastewater, chemical, and high-humidity applications. Surface treatment and material grade should be confirmed according to the service environment.

Edge Banding and Fabrication Options

Factory fabrication helps reduce on-site cutting, improve fit-up accuracy, and shorten installation time. Canri can review drawings for custom serrated grating panels and fabricated access solutions.

Standard Trim Banding

Trim banding uses a flat bar welded around exposed grating edges. It improves panel appearance, protects open bar ends, and provides a cleaner finished edge.

Load Banding

Load banding may be used when grating edges are exposed to concentrated load, repeated traffic, impact, or vehicle movement. It helps reinforce the panel edge and distribute loads more effectively.

Toe Plate / Kick Plate

Toe plates can be added to platform edges, maintenance walkways, and elevated access areas where tools, materials, or debris may fall from the platform.

Stair Nosing

Serrated grating stair treads can be supplied with nosing to improve visibility and traction at the step edge. Visit Steel Stair Treads for related products.

Fasteners and Installation Methods

Serrated grating panels may be permanently fixed or designed to be removable for maintenance access. The installation method should be selected based on the support structure, loading condition, maintenance frequency, and whether welding is allowed on site.

Welded Fixing

Welding is suitable for permanent installations where the panel does not need to be removed regularly. It is often used for fixed industrial platforms, walkways, and structural flooring.

Saddle Clips

Saddle clips can be used to secure removable grating panels to support steel without welding the full panel. They are commonly selected for maintenance platforms and access areas.

G Clips

G clips are installed from the top side of the grating and can be considered where access below the platform is limited.

J Clips

J clips may be used for close-mesh grating or configurations with narrow bearing bar spacing.

Weld Lugs and Bolted Connections

Weld lugs and bolted connections can be considered for removable panels, access hatches, inspection covers, and installations requiring repeated removal.
