Commercial steel buildings are prefabricated and custom-designed for use as offices, stores, distribution centers, freight terminals, service stations, aircraft hangers, commercial garages and more. Since they can be molded into a range of shapes and sizes, steel buildings are finding applications in most any industry imaginable.

All commercial steel buildings are pre-engineered at the manufacturing site and shipped out along with their components to the construction site for assembling. They are particularly advantageous as they can be easily increased in length and number. Since steel does not require much space for support columns, there is more usable free space, making it more suitable use in large warehouses and airplane hangers. Most manufacturers have trained staff who deliver and lay out the components. This makes construction easier and more efficient.

In addition to their low structural maintenance, and durability, accurate price estimates make steel buildings more attractive in the commercial sector.

Commercial steel buildings come in three major categories. The first is steel framed, wherein just the structure or the frame is made of steel, and the external finishing is done with other conventional material such as stucco or brick. This is common in offices, houses and other smaller establishments.

The next category is steel pole buildings, wherein posts and trusses are replaced with steel and then the roof and walls are sheathed with metal. These buildings, also known as pole barns, are more often used in the agricultural sector.

Lastly, steel arch buildings, made of arched steel panes, are the easiest to erect and are most often used for industrial and agricultural purposes. They are completely made of steel and molded in the form of an arch, which serves as both the roof and the wall. They are mostly used in do-it-yourself construction.

A steel building from any of these categories can offer an affordable and durable option for construction.
