I-bar welded steel grating is manufactured by resistance welding I-shaped bearing bars and cross bars into a strong and lightweight panel. Compared with conventional flat bar grating, the I-bar profile reduces weight while maintaining excellent load-bearing performance, making it a cost-effective solution for industrial flooring and access platforms. It is widely used for walkways, platforms, stair treads, and drainage covers where reduced dead load and reliable structural performance are required. Zhongzheng offers custom sizes, bearing bar spacings, and surface treatments to meet ANSI, AS, EN, and other international standards.
Features & Characteristics
- Lightweight Design. I-shaped bearing bars reduce the overall panel weight while maintaining excellent structural performance.
- High Load Capacity. The welded construction provides reliable strength and stability for industrial flooring, platforms, and walkways.
- Material Saving. The optimized I-bar profile reduces steel consumption, making it a more economical solution for many applications.
- Excellent Drainage & Ventilation. The open-grid design allows water, air, light, and debris to pass through freely.
- 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, spacings, panel dimensions, and surface treatments to meet specific project requirements.
