Design Your Perfect A-Frame Steel Barn

Some people assume that all A-frame steel barns are the same, but you know where assuming gets you! With THE BOSS, you can customize your A-frame barn in several ways. Choose your own building measurements, steel gauges, door & window options, colors, and so much more!

Size & Style

What animals, equipment, or supplies do you need to protect and house? We can provide A-frame steel barns to accommodate a number of items, including up to three passenger vehicles. You decide the width, length, and height of barn that works best for your needs. Got some special design considerations? We can help with that, too!

Choose Your Gauges

14-gauge is a typical standard for steel barns, but you may want to consider a thicker 12-gauge for an even sturdier building. The gauge you choose for your metal roofing and side paneling is for you to decide, as well.

Door & Window Options

A steel barn isn’t much good if you don’t have easy access to it! We offer garage-style doors and other doors in different sizes and varieties, and you decide where you want to place them on your barn building. What about letting in some natural light and ventilation? You can add windows to your barn, as well.

Roof Style Options, Too

You’re not just tied to going with an A-frame style roof for your barn. Looking for an even more economical option with a rounded look? Consider a regular roof. Need a barn with additional reinforcement and the functional benefits of vertical metal paneling? Go with our premium vertical roof option.

Colors & More Colors

Your A-frame roof barn can be so much more than boring. What color or colors would you like to choose for your roof, side paneling, and trim? We have many popular color choices for you, and you can mix, match, or two-tone your colors, too..

More Ways to Customize, Too!

You Can Do More With an A-Frame Barn

An A-frame steel barn is much more versatile than “traditional” wood barns. Obviously they’re good for stabling horses or storing hay, but there are so many other ways you can use one of these sturdy steel barns:

Horse barn or stable

Indeed, these barns make excellent spaces for keeping horses, tack, and other supplies.

Hay barn

Great for keeping your hay, grains, feed, and seed dry, protected, and secure.

Shelter for tractors or other farm equipment

An A-frame barn can be designed large enough to accommodate a tractor, combine, or other farm equipment.

Garage & Multipurpose Storage

Don’t just house your farm equipment; you can also protect your personal vehicles too! Also great for RVs, boats, or other large vehicles. Need some outdoor storage space for stuff that no longer fits in your house? An A-frame barn can offer you the space you need!

We Are Happy to Offer Certified Barn Options

What’s a certified barn, you may ask? Steel buildings are already stronger and more durable than wooden buildings or other similar structures by nature. Steel is just stronger than other building materials! A steel barn that’s been certified means that it is professionally engineered to meet or exceed local building codes and requirements regarding specified wind and snow loads.

Do you need your barn to be certified? Honestly, that really depends on how you plan to use your barn, as well as what your local building codes and regulations may require. Even if a certified barn isn’t legally required in your location, we still encourage all of our customers to consider choosing certification. Certified buildings are just designed and constructed to be a little more rugged, so they also offer greater peace of mind.

A-Frame Barns in Different Sizes, at the Right Price

THE BOSS can help you design the A-frame barn you need, and then get it engineered it to meet your exact specifications. A 42’x21’ three-section A-frame barn is a great starting point for accommodating horses, livestock or other items. It includes an 18’-wide center building, with 12’-wide lean-to sections on either side. We can go wider or longer with your building, too. And if you need to go even bigger, we can offer you one of our larger vertical roof barn options. We’ll got you covered at Boss Buildings!

It’s great to get the barn you need, but it’s even nicer when you can get it cheaper! That’s what THE BOSS does for you! How? We work directly with the manufacturers themselves, so we’re able to sell for less. Your individual price will depend on a few deciding factors, including your barn’s size, the customization options you select, and the specific location where your barn will be installed. And here’s one more way we save you money, time, and effort – we deliver and install across our service area at NO additional charge, AND we can install on almost any foundation surface!
