11 Steel Building Sizes to fit your needs

While these 11 sizes are some of the most popular steel building sizes, there is no actual "standard" size for a pre-engineered steel building.  We can design the building to whatever spec you have to fit your property or space needs.  Need a 36x44?  We can do it.  How about a 55x80?  We can do that too.  Even if you need 130x200, we can help.  If you don't see it here, give us a call so we can work with your specs.
Your steel building size can depend on many factors.  Sometimes the size of your lot and any set back requirements will determine the width and length.  Other times is what you need the building for that dictates the size.  For commercial properties, the land set backs and amount of parking spaces will govern your steel building size.  Whatever the determining factor, we can accommodate whatever size you need.  With that being said, we have seen a trend for a number of building sizes that tend to be most popular among our customers.


This illustration shows a 40x60x10 Steel building with one opening for a roll up door and a single walk door.  Part of what makes this steel building size so popular is the versatility and economical design.  It is typically designed with 3-20' bays giving you space for multiple roll up doors for additional access.  With a taller eave height, you have a great space for storing taller vehicles and equipment and still have space for parking smaller vehicles.  If your using it for a workshop, you should have ample space for storing materials in addition to your work area.

With a few options, you can also dress this building up to make it compliment it's surroundings.  Eave extensions, wainscot and a colored roof really dress a building up nicely.


Our next popular steel building size is a 30x40.  With 1,200 sq ft of open space to work with, it's no wonder this is the choice size for many of our customers.  Designed with 2-20' bays, you have room to add another roll up door on the front.  It is small enough to fit on many lots, but big enough to fit your needs.


Another favorite steel building size is a 30x50 with 1,500 sq ft of open space.  Economically designed with 2-25' bays, you get additional square footage without adding much more heavy steel in terms of I-beam main frames.


Our next size is a 40x40 steel building.  Giving you more depth than a 30' wide building, you gain the ability to add a door to the back of the building so that you can pull straight through with either a large vehicle or maybe a truck with a trailer attached.  This makes for a convenient method to load or unload product or equipment while being sheltered from the elements.  1,600 sq ft of space makes this steel building size very desirable for many uses.
