Galvanized steel Grating, is extremely strong and durable for all load bearingapplications and is primarily used for pedestrian and light vehicle traffic. Ourgalvanized coating process provides for years of corrosion resistance in acidicand high moisture environments.

Galvanized steel Expanded Metal is a sheet product that has been slit andstretched to diamond shaped openings. Galvanized expanded metal offerssavings in weight and allows free passage of light, liquid, sound and air whileproviding corrosion resistance in harsh environments.

1. Bearing Bar - Loading carrying bars made from steel strip or slit sheet or from rolled or extruded aluminum, extending in the direction of the grating span.
2. Cross Bar - The connection bars, made from steel strip, slit sheet or rolled bars or from rolled or extruded aluminum, which extend across the bearing bars, perpendicular to them. They're bent into a corrugated or sinuous pattern. Where they intersect the bearing bars, welded, forged or mechanically locked to bearing bars.
3. Bearing Bar Centers - The distance center to center of the bearing bars.

4. Cross Bar Centers - The distance center to center of the cross bars.
5. Band - A flat welded to a side or end of grating panel. Or along the line of a cutout, extending neither above nor below bearing bars.
6. Toe Plate- Also called kick plate. A flat bar attached flat against the outer edge of grating or rear edge of tread. Projecting above the top surface of grating or tread to form a lip or curb.
7. Length - Refer to span of grating.
8. Width - The overall dimension of grating panel. Measured normal to the bearing bars.
