Shear Strength of Expanded Metal Grating

Shear Strength of Expanded Metal Grating

Shear Strength of Expanded Metal Grating

(OP)
I have a situation where there are some catwalks constructed of 3 psf expanded metal grading welded at 8" o.c. to perimeter angles.  If I can get this to act as a diaphragm (which I know it will to some extent) I can avoid adding cross bracing directly beneath this grating.  Does anyone know what diaphragm strength I can get from expanded metal grating?

RE: Shear Strength of Expanded Metal Grating

Call a metal grate manufacturer and see if they can give you some guidance.  

Although there is undoubtedly some shear strength, do not rely on it without documented justification.
