I-bar Swaged-locked Aluminum Grating is manufactured by inserting aluminum cross bars into pre-punched I-shaped bearing bars and permanently locking them through high-pressure swaging. The unique I-bar design provides a higher strength-to-weight ratio compared with traditional flat bars while reducing material usage and overall weight.
Made from high-quality aluminum alloys, this grating offers outstanding corrosion resistance, making it suitable for environments exposed to moisture, chemicals, and harsh weather conditions. It is widely used for platforms, walkways, stair treads, and access areas where lightweight construction and long-term durability are required.
Features & Characteristics
-Lightweight & High Strength. I-shaped bearing bars provide excellent load capacity while significantly reducing the overall weight of the grating.
-Excellent Corrosion Resistance. Aluminum construction offers natural resistance to rust, moisture, and chemical corrosion, ensuring long service life.
-High Strength-to-Weight Ratio. The optimized I-bar profile delivers superior structural performance with less material consumption.
-Slip-Resistant Surface. Available with serrated or anti-slip surfaces to improve safety in wet or slippery environments.
-Low Maintenance. Aluminum grating requires minimal maintenance and maintains its appearance over long-term use.
-Easy Installation & Handling. Lightweight panels are easier to transport, cut, and install, reducing labor costs during construction.
-Customizable Options. Available in various bearing bar heights, spacing configurations, panel sizes, and surface treatments to meet different project requirements.
