But if you’re looking for one you can rely on for years to come, that will never let you down, and you won’t have to put too much work into after install, you’ve come to the right place. Here at Union Steel Structures, we offer a large selection of custom steel buildings to choose from, all of which can be customized to your exact specifications. And before you start to say that this isn’t an option due to finances, take a look at everything you’ll gain by investing in one of these prefab metal buildings.

What Exactly Are Metal Buildings?

Prefab metal buildings are just that – prefab! Each of these structures are designed to your specifications before being engineered in one of our dedicated manufacturing facilities. They arrive on-site, ready to be assembled. And because they arrive ready-to-go, the time needed for installation is cut nearly in half! Our steel structures are the most flexible solution offered to builders, contractors, business owners, homeowners, do-it-yourselfers, and their families. Whether you’re in need of a personal, residential, agricultural, or commercial solution, you can find the perfect answer right here at Union Steel Structures.

Advantages of Metal Structures

You may be asking yourself, “Why should I buy one of these metal buildings? What makes them so special?” Well, allow us to give you some insight as to why these are the best solution you could find on the market today.

Easy to Install – Our pre-engineered units will arrive to your install site ready for assembly. With the right motivation and hard work, they can be completed within just two to thirty days! That’s crazy compared to several months of a traditional wooden building being assembled.

Low Construction Cost – The steel components that are used for these structures are designed to easily fit together. They are cut and prepped in a manufacturing facility, significantly reducing the cost of assembly. And due to being virtually maintenance free, you won’t have to worry about spending extensive amounts of money on labor or maintenance.

Energy-Efficient – Precise engineering, you can be assured that the doors and windows will close tightly, reducing the escape of warm and cold air. And if we hadn’t mentioned it already, these metal buildings are also almost 100% recyclable! So, when they’ve reached the end of their lifespan, they won’t waste away in a dump, they can be reused for a variety of purposes.

Durable – Each of our prefab steel buildings are made with solid steel components, guaranteeing their overall strength, durability, and longevity. They are built specifically to stand strong against extreme weather conditions.


One of the most important aspects of your steel building is its roof. Not only does the roofing system complete the structure, but it provides the contents of the unit with exceptional protection year-round. We have three available roofing options here at Union Steel Structures, more information for each style listed below.

Regular Roof

A regular roof is the most economical style offered in the metal building industry. They are designed and installed with rounded edges and horizontal panels that run from end of the structure to the other. These simple roof styles are best suited for areas that do not typically experience high winds or heavy precipitation. Their biggest advantage is having an affordable price tag.

Vertical Roof

Out of the three roof styles we have here at Union Steel Structures, the vertical system is the most efficient, durable, and longest lasting. Its vertically aligned paneling and additional framing pieces allow it to withstand much harsher weather conditions. While it is built for all climate types, it is best suited for areas that receive extreme weather. It is also required for structures longer than 31’.

A-Frame Horizontal Roof

A slight upgrade from regular roofs, our A-frame horizontal roofing systems are also installed with horizontal panels. However, their more complex designs make them a wonderful option for buildings that will be installed in warmer areas that may receive some high winds, but light precipitation. Their primary advantage is the ability to own an A-frame style structure without the cost of a vertical roof.

All of our buildings come standard with some type of bracing, from 4 braces up to one each leg, depending on the type of building purchased. For those buildings in which the bracing is an optional feature we recommend 2’ braces on buildings 8’ or shorter and 3’ braces on buildings 9’ or taller.

Wind Ratings & Snow
Loadings for Metal Buildings

Depending on the area you live in and the typical weather conditions there, your structure may need to be engineered to meet certain wind and snow ratings. These ratings will tell how strong of wind gusts the unit can take and how much accumulating snowfall it can uphold. Some areas may not experience as much wind or snow as others, so you won’t have to worry about the structural integrity of your building. However, if you live in an area that is prone to high winds or heavy snowfall, you will need to check with your local building department about their required wind and snow load ratings.
