We’re going to look at pricing both the steel building and other construction considerations for an 18×20 metal building kit. An 18 x 20 metal building has become the most common size for residential use. The 18-foot width of this building allows you to include both a standard garage door as well as a man door for easy access. The most common uses for this size of building are:
- Single Car Garages
- Home Workshops
- Small Equipment Storage

18×20 Quonset Hut BuildingsA Quonset hut is a popular choice for this size of building. The main reason for this is that it’s quite simple to build your own quonset and many residential customers want to handle construction to save on costs. Quonset Huts are manufactured in a factory and ship to you typically on a couple of pallets. It is comprised of Steel panels that bolt together to create arches. These arches are then bolted together in a row to create the walls and roof of the building. Quonsets come in a few different profiles. The thought of a semi-circular military building may first come to mind, but these days you can purchase Quonset in multiple shapes including more traditional looking ones with straight sidewalls and a peaked roof.
Rigid Frame BuildingsWhile a rigid frame building is an option for your 18 x 20 building, we don’t typically recommend them for buildings of this size. The reason for this is that unlike Quonset hut buildings, a rigid frame steel building will typically require professional construction assistance due to the weight of the Interior steel frame that is used. You could of course have a rigid frame building in this size, but it’s kind of Overkill as the span of this building does not require the heavy gauge steel framing this type of building comes with.
18×20 Light Frame Metal BuildingsA light frame steel building would be our second recommendation for this size of structure. This type of building is sometimes called a c-channel building. It also uses an internal frame with steel cladding on the outside, similar to a rigid frame, but the steel frame is a much lighter gauge and is often in a ‘c’ shape. The main reason we recommend a Quonset over a light frame steel building is due to the longevity of the structure. The gauge of Steel used on Quonset walls would be heavier than you would see in a typical light frame steel building. This extends the life of your building and can help make it a better investment for your property.
