Capacities to nearly 1.5 million bushels
Higher peak load ratings
Larger roof decks
UNMATCHED ROOF SYSTEM
CLEAR SPAN ROOF SYSTEM
The Big Bin® Series offers an enormous, clear span roof system designed for strong winds, snow loads, temperature cables and high volume filling equipment. The 30° roof allows for optimum filling, and the huge deck at the peak easily accepts today’s ever larger catwalks and higher capacity filling equipment.
The 11” or 15” deep continuous I-beam rafters from eave to peak provide a strong framework for roof loads. This roof system is capable of supporting uniform loads of 50,000-100,000 lbs. (depending on model) at the peak and 40 lbs. per sq. ft. ground snow load.
INNOVATIVE ROOF SYSTEM
STRONG STANDING SEAM PANEL
System uses a “Standing Seam” panel to elevate the roof fasteners above the roof valley. The roof panels are attached to the roof skelton with standing seam roof straps.
RIGIDIZED ROOF PANELS
Roof panels are rigidized for longer life and attach with numerous bolts to the wall system through a continuous angle at the eave. This prevents panels from tearing loose in high wind conditions.
EXTRA HEAVY-DUTY TENSION PIPE
BRINGS ALL MAJOR COMPONENTS OF THE BIN TOGETHER
These massive pipes (up to 4½” diiameter) connect the rafters to the wall panels and stiffeners for outstanding strength at this critical location. This full circle ring at the eave stabilizes the roof and walls under all loading conditions and provides unmatched strength in both tension and compression situations, and provides support of non-uniform loads created by snowdrifts, high winds and earthquake forces.
LARGE ROOF DECK
IMMENSE 13’ 4” DIAMETER DECK
The fill opening can easily accommodate up to 4’ diameter spouting for maximum flexibility in choosing your fill equipment.

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.
