STIFFENED BIN ROOF SYSTEM

BROAD ROOF DECKS

The stiffened series of bins has broad roof decks with large diameter openings and a variety of peak loads available to meet customer needs.

ROOF DESIGNED WITH UNIQUE FEATURES

The roof panels are rigidized between the extra tall 3-1/2" high ribs and attached at the eave with a continuous angle iron and rib brackets giving added strength against wind.

TYPICAL GRAIN DENSITIES:

Wheat approximately 800 kg/m3 (50 lb/ft3)
Corn approximately 720 kg/m3 (45 lb/ft3)
Rice approximately 580 kg/m3 (36 lb/ft3)

* Capacities based on bin filled to eave with grain peaked in roof area at 28 degree slope. Bushels based on 1.25 cubic ft./bu. Metric ton calculations assume wheat at 800 kb/cubic meter; corn at 720 kg/cubic meter and rice at 580 kg/cubic meters. All maximum capacities include a 6% compaction allowances as determined by the American Society of Agricultural Engineers (ASAE) standard S413.
