Pedestrian Traffic Metal Treads
Product Description
Galvanized Steel Perforated Metal Stair Treads ISO9001
Galvanized Steel Grating is an extremely strong and durable solution for all load-bearing applications, primarily used for pedestrian and light vehicle traffic. Our galvanized coating process ensures years of corrosion resistance in acidic and high-moisture environments.
Galvanized Steel Expanded Metal is a sheet product that has been slit and stretched to create diamond-shaped openings. This solution offers weight savings while allowing free passage of light, liquid, sound, and air, while maintaining corrosion resistance in harsh environments.

Glossary of Terms
  • Bearing Bar - Load-carrying bars made from steel strip or slit sheet, extending in the direction of the grating span.
  • Cross Bar - Connection bars that extend across the bearing bars, perpendicular to them, welded or mechanically locked at intersections.
  • Bearing Bar Centers - The distance center to center of the bearing bars.
  • Cross Bar Centers - The distance center to center of the cross bars.
  • Band - A flat welded to a side or end of grating panel, extending neither above nor below bearing bars.
  • Toe Plate - Also called kick plate, a flat bar attached against the outer edge of grating to form a lip or curb.
  • Length - Refers to span of grating.
  • Width - The overall dimension of grating panel measured normal to the bearing bars.
