Determine the Type of Grating You Need
Width of Bar
Depth of Bar
Grating Mesh
Span in Feet
  1. Use decimal numbers only.
  2. Concentrated Load is at mid span across one foot of width.
  3. To calculate Aluminum I-Bar values, use a bar thickness of 0.1875" and the depth of the I-Bar.
  4. Fiberstress calculations use 12,000 psi for aluminum, and 18,000 psi for steel.
