9/10/2023 0 Comments Metal grain siloWhen it comes to timing and quality, a metal silo can be fabricated in weeks and then shipped to its destination - sometimes in one piece - for easy installation. This means less of a facility’s footprint will be taken up by storage and that grain will be stored in carefully regulated conditions that prevent various forms of feed degradation such as fermentation. On the value side of things, a metal silo is a relatively inexpensive, long-term vertical storage solution. Why Metal Is Generally Best for a Bulk Corn Siloįor the customer looking for value, speed, and quality, metal will generally be the best option for a bulk corn silo as metal silos provide the most vertical storage capacity per dollar, can be fabricated and installed quickly, and are built in controlled environments. This can be mitigated with thicker plate, welded construction, and stiffening rings.Ĭorrosion - While all silos are subject to damage from abrasion and impact, metal also has to contend with rust.įlow limitations- If inward-facing welds aren’t done properly, they can restrict material flow. Structural integrity - Metal silos can be subject to vertical buckling. While not as cheap as plastic bag silos, metal silos are much less expensive than concrete silos with welded metal construction being a bit pricier than bolted metal.Īlthough they typically provide the best value for long-term vertical grain storage, metal silos have a few limitations that should be weighed when considering them for bulk corn storage. Metal silos can be fabricated is sizes less than 30 feet in diameter as well as greater than 30 feet in diameter, and can be up to nine stories tall. Diminished flow - Compared to metal, concrete facilitates less flow unless it is lined with a supplementary material such as ceramic or polyurethane.Ĭracking - Concrete is very rigid and can crack if subjected to significant force such as that caused by an earthquake.Ī metal bulk corn silo will usually be made out of thick carbon steel plate.Strict foundation requirements - Concrete silos have to be built on firm soil that can support the substantial weight of the structures.Difficult to accessorize - Adding industrial access equipment such as doors, platforms, and ladders can be challenging when dealing with a concrete silo.Variable timelines - Because concrete silos are constructed on site, they involve many contingency factors, such as weather conditions, that can lead to unexpected delays.For concrete silos to be cost-effective, they should only considered for applications that require silos with diameters greater than 30 feet.īesides cost, a few other limitations should be taken into account when considering a concrete bulk corn silo: As such, they are the most expensive of the three options under consideration when it comes to building a bulk corn silo. Rodents and debris from nearby farming equipment frequently breach bag silos.ĭifficult to unload - There’s no using gravity to flow grain out of a bag silo it has to be pumped out.Ĭoncrete silos are custom, permanent installations that are built on the premises. Breakage - A plastic sheet is relatively easy to pierce.Large footprint - Bag silos lie on the ground, taking up a lot of space on a horizontal axis. ![]()
