Galvanized Steel Bar Grating for Industrial Platforms and Trench Covers
Steel bar grating is a heavy-duty open-grid flooring solution made by welding load-bearing flat bars and cross rods into a rigid panel. It is commonly finished with hot-dip galvanizing, forming a protective zinc layer that ensures long-term corrosion resistance even in harsh environments. This makes it ideal for industrial platforms, walkways, trench covers, stair treads, ramps, and catwalks.
Types of Steel Bar Grating
- Plain Surface: Flat bearing bars for standard usage with easy cleaning.
- Serrated Surface: Anti-slip design for improved safety in wet or greasy conditions.
- ADA-Compliant (Close Mesh): Reduced bar spacing to accommodate wheelchairs and high-heel pedestrian traffic.
Product Features
- High Load Capacity: Designed to handle heavy vehicle and foot traffic.
- Superior Corrosion Resistance: Hot-dip galvanized surface protects against rust and wear.
- Slip-Resistant Options: Serrated surfaces increase grip for safety in hazardous conditions.
- Efficient Drainage: Open-grid design allows water, snow, and debris to pass through easily.
- Customizable Sizes: Available in a wide range of dimensions and bar spacing options.
- Quick Installation: Panels can be welded or secured with mounting clips.
