Strength and Stability are engineered into our bins

Were 100% committed to 2.66" corrugation because we know it’s simply the best? Commercial grain storage systems are no place for compromise. That's why we use 2.66" (6.76 cm) corrugation on every sidewall sheet- everyone. It's best for hoop load, wind load and is performance proven over the years. This corrugation specification provides more steel per square inch when compared to wider corrugation of the same thickness- and that matters when you have tons of grain inside the bin.

1.5mm to 5.5mm we’ve extended our range of sidewall gauges to match an even wider range of commercial bin applications. These heavier gauges reduce the lamination requirements on larger bins- reducing bin costs and saving time and money in construction.

350 GSM - 600 GSM galvanization on every sidewall sheet means 27% longer life. 1.5mm to 5.5mm sidewalls available allowing us to design each bin to match your application. All sheets are identified for thickness, supplier, coil and date for easy traceability. Precise 7/16" sidewall punching easily accommodates 3/8" bolts, saving time during construction.

Bolt-on base angle provides a strong finished edge to bin bottom and secure seal of bin to foundation when a sealer is added-providing greater integrity over competitors' pre-formed angles that are simply rolled into the sheet.

Roof Systems
Quality starts at the Top

Options to match your commercial bin requirements.

Bali Group offers you a range of roof systems to match your commercial installation requirements and your budget.

72 ft. to 105 ft. Models (21.9 m to 32 m): Larger models typically need extra support due to larger capacity conveyers, catwalks and heavier spouts.
30 ft. to 60 ft. Models (9.1 m to 18.3 m): Option of raftered or non-raftered roof system.
Up to 30 ft. Models (Up to 9.1 m): Non-raftered roof systems are standard and generally meet or exceed roof load requirements for these sizes.

Every roof design has been tested for fit at the factory. All roof designs were initially assembled by our engineers before the first one shipped. This extra quality step means you don't have to worry about dealing with a "prototype" during installation. Every bolt hole lines up. Every sheet matches. Rafters and purlins are precisely manufactured. We know. Because we already built each size in-house before they were released to manufacturing and shipped to customers.

Engineered for long life and trouble-free construction:

350 GSM - 600 GSM galvanization on all outer roof sheets and most raftered components, leading to 27% longer life on areas exposed to the elements. Components that require welding are not galvanized, but are powder coated for optimal protection. 30° roof slope helps void debris and snow from the roof system, without increasing overall bin height.

Temperature cable brackets are easily added to raftered roofs with minimal expense.
Powered roof exhausters are easily added with trouble-free installation on site.
Gooseneck vents with corresponding pre-formed vent opening allow for easier installation.
Three roof panels per sidewall sheet also simplify installation.

Proprietary state-of-the-art roll former controls the distance between holes from rib-to-rib, not from the edge of the coil like competitive products. The result: Higher quality roof sheets that fit better- with bolt holes that line up every time. Bolts drop right in place. That means trouble-free, labour-saving, frustration-free installation on site.

Stiffeners

Structural integrity at every point.
Stiffeners provide integrity and optimal strength for the high eave heights typical of commercial grain storage bins. The stiffeners carry the vertical load, allowing the sidewall to account for hoop load. Choice of two or three stiffeners per sidewall panel provide optimal strength and stability depending on capacity and application. Stiffeners are easily mounted either externally or internally depending upon customer preference.

All stiffeners are 350 GSM - 600 GSM galvanized to provide 27% longer life. Most stiffeners are ASTM A653 Grade 55 with 55K yield and 70K tensile strength. Stiffeners are available from 1.5mm to 4mm to meet the demands of bins up to 105 ft. (32 m) diameter.

G115 galvanizing of stiffeners provides up to 27% longer life. Most stiffeners are ASTM A653 Grade 55 with 55K yield and 70K tensile strength.

12 gauge splice ensures that stiffeners are properly butted to effectively transfer vertical sidewall load to the foundation.

Heavy duty wind rings are easily attached to the stiffeners on bins requiring this extra measure. Pre-punched wind ring holes and special attachments simplify installation.

"Hat shaped" stiffener design is proven through engineering studies to be the preferred shape for commercial bin stiffeners. This design carries the full vertical load to the foundation.
