Serrated welded steel grating is manufactured by resistance welding serrated bearing bars and cross bars into a rigid and durable panel. The serrated surface provides enhanced slip resistance, making it an ideal choice for wet, oily, or hazardous working environments. It is widely used for industrial platforms, walkways, stair treads, offshore facilities, and drainage covers where safety and reliable performance are essential. Zhongzheng offers custom sizes, bearing bar spacings, and surface treatments to meet ANSI, AS, EN, and other international standards.
Features & Characteristics
- Enhanced Slip Resistance. Serrated bearing bars provide excellent grip, reducing the risk of slipping in wet, oily, or icy conditions.
- High Load Capacity. The welded construction delivers outstanding strength and structural stability for demanding industrial applications.
- Excellent Drainage & Ventilation. The open-grid design allows water, air, light, and debris to pass through freely, keeping working areas clean and safe.
- Corrosion Resistance. Available with hot-dip galvanized, painted, or black finishes for reliable protection and long service life.
- Low Maintenance. The durable welded structure requires minimal maintenance, reducing long-term operating costs.
- Custom Manufacturing. Available in various bearing bar sizes, serration patterns, mesh spacings, and panel dimensions to meet project requirements.
