The Capabilities of Silos in Mild Steel, Stainless Steel and Aluminium!

Storage solutions for bulk materials and silos have existed since the eighth century BC and have been used in a variety of different ways (mainly in agricultural deployments) throughout human history.

The earliest silos were manufactured out of whatever natural materials may have been available in that particular region at that point in time, but today’s silos are incredible marvels of modern engineering and almost always take advantage of the most advanced construction materials available.

Silos are still commonly utilised  in the agricultural world and are also used in the military across most industries where the maintenance and storage of components and materials is required. Recently they have even been converted into high-end luxury real estate investments!

However, if you are looking to take advantage of a silo for the purposes they were originally intended for (the bulk storage of materials) the odds are pretty good that you are going to be looking to leverage the right construction material for the task at hand.

While there are all different kinds of materials that you may decide to take advantage of – as we highlighted above – the overwhelming majority of industrial and agricultural options today are designed out of three different materials:

  • Mild steel
  • Stainless steel
  • Aluminium

Each of these different materials are utilised for varying reasons, and you are going to be completely certain that you’re always maximising the capabilities of silos that have been manufactured out of three materials outlined above.

To really help you make the most out of your new silo investment (and to be sure that you know exactly what you’re doing when you dive into this kind of research) we’ve put together some information to help you better understand the capabilities of different materials that construct silos.


Mild steel silos meet the needs of diverse industries:

The overwhelming majority of the “industrial focused” silos today are going to be manufactured out of mild steel for a variety of different reasons.

For starters, this construction material is incredibly robust and relatively easy to work with, making it an ideal solution for the mass production of these kinds of installations.

On top of that, the material itself – and the finished product – is tremendously durable and very corrosion resistant (on the inside as well as the exterior). This means it is going to enjoy a very long functional life with very little maintenance or repairs necessary along the way.

Mild steel is an Ideal solution for those involved in the chemical industry, the ceramic industry, the paper industry. Also those looking to leverage silos in the power and energy world, water and sewage community, and the oil and mining industries, mild steel meets most every demand.


Stainless steel silos are fantastic when looking to contain large quantities of liquids and other bulk materials:

Mild steel silos are considerably heavier than mild stainless steel silos. They are usually designed or at least optimised to take advantage of the properties of stainless steel to provide efficient and safe storage for large quantities of liquid. This ranges from juice, water, corn syrup, chemicals, and a whole host of other liquids that need to be kept safe and kept out of contact with a variety of different environmental factors. These kinds of silos are most commonly used in the beverage and agricultural world, though pharmaceutical industries are taking advantage of these silos as well.

Stainless steel is one of the most effective and “sterile” construction materials you are going to have the opportunity to take advantage of when you need a silo that can store potentially volatile liquids for extended amounts of time. This is probably their biggest advantage over the other options available.


Aluminium silos usually represent the least expensive silo options available:

They are incredibly lightweight, relatively easy to construct, and inexpensive when compared to other options manufactured to the same specifications utilising some of the other materials we have highlighted above. Aluminium silos are incredibly popular because of their strength to weight ratio, adaptability and flexibility, and their low price tag.

These silos do have to be treated with external solutions to better prepare them for life outside. These kinds of silos are going to require regular inspection and maintenance to make sure that they are still able to provide you with the safe and consistent results you are looking to take advantage of.
