The grating is 1” x 3/16” (18” x ~34”) aluminum with a safe load of 632 lbs per square foot for a 24” span, our unsupported span is 15”. The channel is 6061 aluminum 4” x 1.58” x 0.18” anchored to the floor with ¼-20 bolts spaced 18” apart. The “L” brackets will keep the grating from sliding much. More of this raised floor could be added to extend to penetrations. Let me know if there are a questions or comments. </p><p class="MsoNormal"> </p><p class="MsoNormal">Thanks, Joe</p><p class="MsoNormal"> </p><p class="MsoNormal"><span style="color:#44546A">Joseph F.
