When you are thinking about different ways to make use of your land, you need not look any further than the barn. Barns are practical pieces of architecture that are also aesthetically pleasing. Because they are useful, they have been around for centuries.
An old-fashioned design is simply a barn-style building with an open top and few walls. Barn metal buildings serve the same purpose only include more modern features such as steel beams and offer new ways to customize your barn.
Simplify your research by letting us do the work for you.
Barn metal buildings (red-iron steel or engineered cold-formed) deliver rugged, low-maintenance protection for livestock, hay, feed, equipment, and shop space—and can be adapted into barndominiums with living quarters. This guide covers costs, sizing, roof styles, code loads, and buyer tips—with real-world examples you can sanity-check your budget against.

Best Uses for Metal Barns
- Livestock & Tack: Wash bay, stalls, tack room, and feed storage with durable metal liner panels.
- Hay & Equipment: Wide, clear spans for tractors, balers, and implements without center posts.
- Shop + Storage: Add roll-up doors and a partition wall for a secure workshop.
- Barndominium: Combine living quarters with a shop under one roof (separate conditioned envelope for comfort).
Design Choices That Affect Price
- Roof profile: Gable for simplicity; gambrel/monitor for classic barn look and loft storage.
- Eave height: 12′–14′ standard; 16′–20′ for equipment, mezzanines, or RV clearance.
- Openings: 12–14′ roll-ups for machinery; add man doors and windows for light and egress.
- Ventilation: Ridge vents, cupolas, and wall louvers to control moisture in livestock/hay areas.
- Insulation: Drip-stop, vinyl-back fiberglass, or spray foam; choose based on use and climate.
Codes, Loads, and Site Planning
Start your spec with the building department: design wind speed, exposure category, and ground/snow loads drive frame weight and cost. Roof pitch and profile also influence snow shedding. In snowy regions, barns often carry 40–70 psf roof snow design depending on jurisdiction.
- Mark setbacks, easements, and drive paths for livestock trailers and deliveries.
- Plan utilities early (power drops, water lines, frost-free hydrants, trench drains, septic).
- Choose slab thickness, vapor barrier, and drain slopes that match your use (stalls vs. shop).
Metal Barn vs. Pole Barn (Quick Compare)
| Factor | Metal Barn (Red-Iron/Engineered Steel) | Pole Barn (Post-Frame) |
|---|---|---|
| Structure | Engineered steel frame, clear spans | Embedded posts, wood trusses |

Barns are a great way to store debris from your homestead or even your tools from your small business. Maybe you have an old truck that is worth restoring, but it’s hard to get around anywhere with it. You can use it as part of your family heirlooms, but you don’t want to leave it out in the open. With a barn metal building, you can put it out of sight and still enjoy knowing that it’s there when you need it.
Barns are also useful for housing livestock. When the weather is nice, you might let your animals graze the land around your homestead. However, when it gets cold or there is a storm approaching, you’ll want to bring them indoors where they will be safe and warm.
If you don’t have a barn metal building to keep them in at night, they could end up protecting themselves from the elements by huddling together in a corner of your yard. A barn is also useful for housing animals that are sick or recovering from an injury.
The commercial metal building industry went up by 3% back in 2018. The pandemic may have slowed down the growth but steel commercial metal buildings will continue to be a popular choice.
Metal Barns
Steel buildings are ideal for keeping livestock. The reason is that they provide shelter from inclement weather and predators. They also protect the animal from its own waste which can be very hazardous to both humans and animals alike. As a plus, barns have tie-down points which serve as an anchor point when it comes to feeding and milking.
Depending on the metal building supplier, barns can also provide storage space for tools and machinery. This way, mechanics and farmers alike can have access to their favorite equipment at all times. They are also used as parking spaces for farm vehicles.
Another advantage that metal buildings offer is that they are easy to clean. This is more difficult for traditional barns as they can harbor insects and even rodents!
In residential areas, some people use metal buildings as metal garages or workshops. In some states, these types of structures may be used as dwelling spaces with a special permit from the local government.
The Benefits of Steel Barn Buildings
Barn metal buildings are made of steel. This is because it is one of the most versatile metals used in construction today. Steel is also easy to clean which means that barns will look brand new even after several decades!
The sturdiness of these structures is another important benefit. They have been tested against harsh weather conditions and are able to stand strong against wind, rain, and snow. This makes them virtually impervious to natural disasters too!
The price of steel may be higher than that of wood but metal buildings are worth their weight in gold. This type of construction is more durable, stronger, and sturdier overall making it a better investment rather than traditional materials used for building barns and other structures.
Metal buildings also save time in construction. As we all know, wood is a very delicate material and requires extra care in manufacturing. Not only that but it will take weeks before they can be used for their intended purpose! On the contrary, metal buildings are ready to use right after fabrication! No need for further finishing or painting.
This is why more and more people are choosing metal buildings over traditional wooden structures. It’s not just because metal buildings look good in pictures but their benefits speak for themselves!
Barn Metal Building Sizes
Barn metal buildings are available in different sizes. You can find the right size that will match your needs. Here are some of the more popular barn sizes that are available today:
- 30 x 30
- 30 x 60
- 50 x 50
- 50 x 60
- 50 x 80
- 60 x 100
- 100 x 200
Each size is ideal for a specific purpose. 30 x 30 Barn Metal Buildings are perfect for storage, but they cannot be used for keeping large equipment. A 100 x 200, on the other hand, maybe too large for other purposes.
Why Use a Barn Metal Building
If you are thinking of building a barn, you should go for one made from steel. While a traditional wooden barn may have its appeal, it has its limitations. But why should you use a barn metal building? A pre-engineered metal structure offers several advantages that you cannot find in other types of buildings. Here are some of the main reasons why you should go for a custom metal barn:
It’s Economical
Perhaps the main advantage offered by prefab metal barns is that they are economical. For a low-rise construction project, it is arguably the best option for you. Compared with a large wooden structure, a steel barn will be cheaper to build.
A major reason why a steel barn is a lot more economical is because of the faster building time it offers. That means labor cost, which is a major part of the construction cost, would be lower. That’s just for starters because steel buildings require less maintenance, they will also offer savings over the long term.
Lower Insurance Rates
This is something that people tend to overlook. Steel buildings have lower insurance rates compared to other types of structures. That’s because they can resist damage from natural calamities better than wooden structures. Steel is also flame retardant so there is less risk of a steel building burning down.
It’s not surprising that many insurance companies offer huge discounts for steel buildings.
Energy Savings
Steel is a very poor insulator, so a structure made from steel will have an abysmal, modern performance when it comes to energy savings. For the most part, barns do not really require heating or AC but a steel barn actually has great potential for energy saving.
Because steel buildings have deep wall cavities that allow the installation of modern insulation. Modern insulation makes these buildings energy efficient. You can potentially get energy savings of up to 50%, which is very substantial.
There are also steel panels that have been coated with special paint that can help reflect the heat of the sun, which will lower the temperature inside prefab metal buildings.
Low Maintenance
A major reason many property owners are using steel barns now is the low maintenance requirement of this type of building. The exterior of wooden and concrete buildings needs a great deal of maintenance work. For example, they have to be painted regularly, not just to keep up appearances but also to maintain the entire structure’s integrity.
Steel structures will require a new paint job from time to time, but it is not as often as a wooden structure. Also, the steel panels would come in prepainted.
Another point that needs mentioning is that Barn Metal Buildings will have no issues with termites. Americans spend over $5 billion each year for termite control. There is no need for you to use harsh chemicals for controlling termites and rodents.
Easy and Fast Construction
If you’re unfamiliar with barn metal buildings, then you may not be aware that they come prefabricated. That means most of the work in building them has already been done.
Think of barn metal buildings as like toys that need to be assembled. All the parts are there, and you just need to put them together. All the parts will be delivered on location, so putting together of the structure should take less time than building a more traditional barn.
Faster construction time also means that you can save money on labor costs.
Fewer Foundation Problems
Steel is a solid material, and because of that buildings made from it would require less framing. Fewer framing would mean that the structure’s overall weight would be far less compared to a traditional building of the same size.
Because Barn Metal Buildings will be lighter, it will mean there will be less load that the foundation will have to bear. In the long run, that would mean fewer foundation problems.
Metal Barn Roof Styles
The metal roofing is usually made from steel or aluminum and is often covered with a layer of protective coating to keep it free of rust. Some roofs fold, others can be shaped like a dome, and some make use of heavy beams for support like the traditional barns.
Steel Barn’s frame has an average width of 1 to 5 feet. Take this into account when ordering your building plan.
The different metal barn roof styles are as follows:
- Truss roofs – The roof system is held together by beams, called trusses. The truss may be wood or steel, you can choose between the two types to fit your needs. Steel truss roofs are usually made with recycled steel materials to keep costs down and reduce weight. It’s usually easier to change the pitch of a truss roof, but have more area to cover.
- Gable roofs – are the most common type of barn roof. This is the one you typically think of when imagining a traditional barn roof. There are two angled panels meeting at a ridge in the center top. The gable roof is easy to build and cover with material to protect it.
- Sawtooth roofs – this type of roof is designed to increase the amount of light reaching inside, so they are often used in farming buildings or greenhouses. The sawtooth roof has a small ridge along its length, with panels running up on both sides at an angle with one end attached to the ridge and the other side resting against it.
- Gambrel roof – is a traditional roof design consisting of two different angled roofs, one small and the other big. The lower part has a steeper pitch than the upper portion to allow more storage space in the lofted area. Its appearance resembles that of a Dutch Barn.
General style notes for metal barns:
- For a traditional gable style roof, the ridge of the panels should be pointing towards the front and back of the building.
- A sawtooth roof can be either on top or on both sides of a metal barn structure for more natural light inside. The design is popular in greenhouses and farming buildings. It can be used with other types of roofs as well.
- A gambrel roof is common in traditional barn styles, usually with a steep lower portion and a higher upper section.
Steel Barns Roof Style
Flat:
These roofs work well for agricultural buildings like dairy farms, where there is a lot of equipment to maneuver around inside. You can add more insulation on these flat or low pitched roofs because they have less air space to fill.
Gable:
A sturdy and traditional roofing option that’s easy to use and comes in many different styles. You can use it with or without a ridge vent, but they’re very effective in areas that don’t get a lot of wind.
Sawtooth:
A metal roof design was originally developed for greenhouses and farming buildings where ventilation is critical. It’s also used in industrial buildings because the open space creates high airflow.
Gambrel:
A traditional roofing style with a higher portion up top to accommodate large hay bales. These are popular in agricultural buildings, but you need more roof space so they can be harder to fit on smaller buildings or ones that have steep slopes.
Mansard:
These roofs are almost flat at the bottom and then rise steeply at the top. They’re often used to create more space in high-density living areas like apartment buildings but can work well for agricultural buildings.
