Sukup Over a Million Bushel Bins

Sukup Commercial Bins are made to handle larger sized operations and so Million Bushel Bins were created.  The Sukup 135′ Commercial Bin was the first free-span bin of this size ever erected.  The Sukup 135′ and 156′ Diameter Commercial Bins were built to satisfy today’s massive grain storage needs.  With 1,200,000 and 1,520,000 bushel maximum capacities, you can maximize your storage space while minimizing the number of bins.

Sukup Over a Million Bushel Bins


Free span-extra heavy-duty – 100,000 lb. roof load rating standard

Roof rating: 100,000 lbs. evenly distributed on peak ring as pure vertical peak load with 40 psf ground snow zone or 90 mph wind zone as defined by ASCE7-05 Code

21′ flat surface platform at peak (156′ dia. bin) allows for conveyor maintenance and provides a flat, safe place to stand while doing inspections or service. Equipped with a handrail.

Roof rings are standard on all Sukup Commercial Bins. Number of rings depends upon bin diameter.


Top quality bolts – JS1000 or equivalent, Grade 8.2

70,000 psi tensile strength steel for sidewall sheets and stiffeners

Heavy-duty corrugated plate attaches sidewall to rafter making for a very strong connection

Triple laminated sheets and exclusive splice plate allow Sukup 135′ and 156′ Commercial Bins to be erected more quickly than other bins of similar size.

Patented splice plates eliminate the off-set in bin sheets, which prevents gaps that would allow grain leakage. This design also utilizes the full strength of the sheets. (U.S. Patent #8,291,664)
