![]() ![]() In short: Don’t hesitate to contact us for your custom metal silo needs.Concrete stave silo under construction in 2015 If you’ve got some measurements and a rough idea of what you want, we can take it from there. It doesn’t take much to get started no fancy engineering drawings needed. We also hot-dip galvanize and paint, as well as fabricate structural steel and industrial access equipment, making us a one-stop shop for just about any custom metal silo needs. Here at Southern Metal Fabricators, we’ve built dozens of metal silos according to all sorts of specifications using just about any type of suitable material. ![]() If you have an unusual material, specific quantities, or restrictive conditions, you’ll be better off with a custom metal silo, which means working with a custom metal fabricator who can build one for you. While there are lots of “off-the-shelf” metal silos out there - whether you’re talking flat-bottom, conical-bottom, or horizontal configurations - they are always going to limit you to what’s available. Raised horizontal metal silos are accessed via stairs, ladders, or a combination of these two types of industrial access equipment, depending on the design. This also makes discharge convenient since gravity will do the work of pulling the stored material out of the silo via a chute or hopper. When installed inside a plant, horizontal metal silos are typically lifted off the ground on structural steel platforms to preserve floor space. Coming in a wide variety of sizes, they can be designed to meet any planning or space restrictions, including those for interior spaces. These types of silos are almost always made using welded construction and finished with durable paint. They are often used to aggregate metal chips, cement, lime, ash, and other waste particulate collected by air filtration systems. Like conical-bottom silos, horizontal metal silos are best suited for short-term storage. This type of silo can also be galvanized or painted to resist corrosion. Metal silos with conical bottoms must be precisely engineered for the material they are meant to store if flow is to be properly controlled. The conical hopper attached to the bottom of these silos allows for an easy, metered unloading, provided the material in the silo corresponds to the silo design. But they are also often made using welded construction, which lasts longer and produces a structure that is less likely to interfere with material flow. Much like flat-bottom silos, conical-bottom metal silos can be fabricated using sheets bolted to structural steel frames. But they are typically used for temporary storage as they often hold smaller quantities than flat-bottom silos and can be raised on structural steel supports to permit access underneath, making loading materials for transport easier. Conical-Bottom Metal SilosĪlso known as “cone bottom silos,” conical-bottom metal silos are also used to store a wide variety of materials, including grain, sand and salt for winter road maintenance, and powder. A sweep auger will also provide controlled flow for a diverse range of stored materials, which means that it can be adapted to store diverse materials over the years - rather than having to engineer a silo for a specific product’s physical properties, as with conical-bottom metal silos. The latter can include spiral stairs that wind around the silo (if it is big enough) and caged ladders to provide access to the inspection door at the top.īy equipping this type of silo with a sweep auger, the material at the bottom can be unloaded first according to the “first in, first out” principle. Important accessories for these large metal silos include wind rings, which stiffen the silos for wind loading and bolster their structural stability during filling and discharge, as well as industrial access equipment. All this metal is usually hot-dipped galvanized to protect it from the elements. While welded construction is available, flat-bottom metal silos are usually built using carbon steel body sheets that are bolted onto a frame made of structural steel stiffeners. Most often, they store grain, meaning that you’ll find them at breweries, feed mills, flourmills, and port facilities, for example. Metal silos with flat bottoms are used to store materials for extended periods of time. Knowing the difference between them - not only in terms of configurations but also applications - can be helpful to anyone who’s setting out to source metal silos. But there are three main types of silos that are typically used in industrial settings. Metal silos aren’t all built alike, especially when they are custom fabricated. ![]()
