Serrated Anti-Slip Steel Grating Factory Direct | Friction Coefficient 0.85 | Q355B High-Strength Material | Designed for Wet/Oily/Sloped Environments
On wet platforms, do your workers feel like they’re walking on ice? In oily environments, do you worry every day about slip accidents?
Ordinary steel grating’s friction coefficient plummets to 0.35 in wet conditions, while our serrated anti-slip steel grating maintains a stable grip of 0.62 even in oil.
With 18 years of expertise in anti-slip steel grating, we operate fully automatic cold-pressed serration production lines and offer a dual anti-corrosion process of hot-dip galvanizing + resin coating. From offshore drilling platforms to chemical plant maintenance walkways, from food processing plants to ports and docks, we deliver safety solutions featuring 47% improved slip resistance and 15 years of maintenancefree performance.
What is Serrated Anti-Slip Steel Grating?
Serrated antislip steel grating, also known as toothed or serrated bar grating, is a metal grid product manufactured by welding serrated flat bars (with 1.5–2 mm deep锯齿like grooves on one side) to twisted square bars, followed by hotdip galvanizing.
Its biggest difference from ordinary steel grating is that the top surface of every bearing bar undergoes special embossing or stamping, forming evenly distributed serrated patterns. These锯齿 effectively disrupt the continuity of water and oil films, creating strong mechanical interlocking between footwear and the surface—delivering exceptional antislip performance.
Three Core Advantages: Why Choose Serrated AntiSlip Steel Grating?
✅ 47% Improved Slip Resistance – Safe in Wet & Oily Environments
According to professional testing, the dynamic friction coefficient of our serrated grating reaches 0.85, compared to only 0.58 for ordinary grating—a 47% improvement in antislip performance.
Even more impressive is its oil resistance: when lubricating oil is present, ordinary grating’s friction coefficient drops sharply to 0.35, nearly losing all grip, while our serrated version still maintains 0.62—a 45% smaller decay in slip resistance.
A petrochemical enterprise reported that after replacing their refinery maintenance walkways with serrated grating, worker slip accidents decreased by 82% yearonyear.
✅ Upgraded HighStrength Material – 50% Higher Load Capacity
We use Q355B highstrength alloy steel instead of conventional Q235B, increasing yield strength by 50%. Combined with precision serration embossing, each individual tooth can withstand 300N shear force without deformation.
Scanning electron microscopy shows that the microroughness of the serrated surface (Ra 3.2–6.3μm) is 2–4 times that of ordinary grating (Ra 1.6μm). This multiscale structure greatly enhances mechanical interlocking at the contact interface.
Through a threestep process chain of “cold pressing – quenching – tempering,” the fatigue life of our products exceeds 2 million cycles, far surpassing the 500,000cycle standard of ordinary hotrolled grating.
✅ Excellent Drainage Design – 83.3% Open Area
The scientifically designed mesh structure of serrated antislip grating achieves a drainage rate of 83.3%—more than double that of cast iron covers. Rain, oil, and wash water drain quickly, preventing surface accumulation and从根本上 reducing slip hazards. The mesh effectively prevents objects smaller than 20mm from penetrating, balancing safety and functionality.
Three Series Specifications – Precisely Matching Application Scenarios
Based on bar spacing, we divide serrated antislip grating into three series to meet different operating conditions:
| Series | Bar Spacing | Core Features | Application Scenarios |
| Series 1 | 30mm | Most common type; maximum resistance to surface impact | Power plants, chemical plants, wastewater treatment plants, grain silos, highways, airports, docks—platforms, walkways, trench covers, stair treads |
| Series 2 | 40mm | Most economical and lightweight; best costeffectiveness | Warehouse shelving, mezzanine floors, catwalks, protective fences, sunshades, lightduty walkways |
| Series 3 | 60mm | Specifically designed for mining; solves mineral spillage problems | Crusher area flooring, conveyor walkways, ball mill areas, processing plants, transfer stations |
Application Scenarios: Comprehensive Safety Protection from Offshore Drilling to Food Plants
Thanks to its exceptional slip resistance, our serrated grating has been widely used in various highrisk scenarios:
| Industry | Application Scenarios | Slip Resistance Requirement |
