20 Gauge Grandstand Chart - 2.66" Corrugation
Narrow/2.66" Corrugation - 20 Gauge Grandstand Floor Support Chart
* For Aeration Systems recessed in the concrete, add one (1) ring for proper spacing.
When using FL-3102-3 or FL-3102-6 (3", 6") Grandstands, increase the listed quantities by 33%
(Standard Quantity x 1.33).
Quantities of Grandstands are minimum required for installation - Due to varying conditions
and construction techniques at floor and wall penetrations, additional supports may need to
be ordered.
How to read the chart: For example, a 12' diameter bin with 7 rings would have spacing of 54/27
(the top numbers). Meaning A=54" and B=27". The number of supports needed would be 62,
(the bottom number).
