 RIGIDIZED ROOF

Behlen's roll formed roof panels are rigidized between the 3½" high ribs. The panels are held securely at the eave with a minimum of 8 bolts attaching the panels to a continuous angle iron and rib brackets. These features work to keep a roof over your crop, even in the strongest storm.

Wall System

WALLS WITH UNIQUE DESIGN FOR ADDITIONAL STRENGTH

STURDY, LONG LASTING WALL SYSTEM

The flat-sided, trapezoidal corrugation, offered as our standard design with all Behlen bins, provides greater strength, rigidity, and wind resistance than other types of corrugation. This, combined with our rigid anchor bracket and roll formed base angle will hold your bin securely in place.

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.
