20 Gauge Grandstand Chart - 4.00" Corrugation
Wide/4.00" Corrugation - 20 Gauge Grandstand Floor Support Chart
* For Aeration Systems recessed in the concrete, add one 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
.
Floor styles in order of increasing strength are 18 gauge Cor-Lok, Cut-Lok, Dura-Lok.
How to read the chart:
For example, a 12' diameter bin with 5 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).
