Serrated press-locked steel grating is manufactured by mechanically locking serrated bearing bars and cross bars together under high pressure to form a rigid, welded-free structure. Combining the clean appearance of press-locked construction with the enhanced slip resistance of serrated bearing bars, it offers excellent structural strength, dimensional accuracy, and long-term durability. It is widely used for industrial platforms, walkways, stair treads, drainage covers, and architectural projects where both safety and aesthetics are essential. Zhongzheng provides customized panel sizes, mesh configurations, serration types, and surface treatments to meet a wide range of project requirements.
Types
| Two standard configurations are available to meet different project requirements. | |
| Full Press-locked (Full Grating) | Half Press-locked (Half Grating) |

Features & Characteristics
- Enhanced Slip Resistance. Serrated bearing bars provide excellent traction, reducing the risk of slipping in wet, oily, or hazardous environments.
- Precision Press-Locked Construction. Manufactured without visible welding, the press-locked construction ensures excellent dimensional accuracy and a clean, uniform appearance.
- Reliable Load Capacity. The rigid press-locked structure provides stable load-bearing performance for industrial and commercial applications.
- Excellent Drainage & Ventilation. The open-grid design allows water, air, light, and debris to pass through freely, improving safety and reducing maintenance.
- Corrosion Resistance. Available with hot-dip galvanized, painted, or black finishes for long-lasting protection in demanding environments.
- Custom Manufacturing. Available in various bearing bar sizes, serration types, mesh configurations, panel dimensions, and edge treatments to meet project specifications.
