Steel Building Designs
There are two main types of designs for pre-fabricated steel buildings: Quonset huts and straight wall buildings. Each type has its own advantages and disadvantages. Both are ideal choices for a wide range of structures. No matter which type you go with, you can make your building as large as you would like.
Quonset huts are also known as “arch designs.” A Quonset hut is essentially that — a single large arch forming an enclosure. The ends of the arch can be walled up or not; that is up to you.
There are three models of Quonset huts:
|The Q-Model is your most basic and popular type of arch building. |
It is the least expensive design, and offers excellent strength, economy,
|The S-model has straight walls on the side and the arch overhead. |
It is great for warehouses and other storage areas since it is easier to utilize all the space.
|The P-Model is the most expensive. This model has straight walls and |
a gabled roof, rather than a standard arch. These are popular for garages and workshops.
Why go with a Quonset hut instead of a straight wall design? They are renowned for their strength. They can stand up to harsh weather conditions and withstand everything from hurricanes to earthquakes. They cost about 30% less than their straight wall counterpart.
Straight Wall Steel Buildings
Straight Wall steel buildings are exactly what they sound like—your traditional buildings with straight walls and a flat ceiling. You can choose a variety of roof spans. There are a number of different designs for straight wall buildings, including Straight Column, Gable, Beam and Column, and Lean-to, also known as a “Wing.”
|Straight Column||Quite typical and can feature gabled or single sloped roofs. They generally used for small retail stores and the like.||20'-70'
|Rigid Frame||This type of structure is for if you need a large open space for a structure like a gymnasium or hangar. These are column-free clearspan systems that keep interior space open and unobstructed.||20'-150'
|Beam-and-Column||These structures offer a great deal of space and are easy to expand. Use if you want to build a warehouse if a building for a factory||80'-300'
|Lean-to or "Wing"||Used to expand an existing structure without disrupting anything going on inside. Remember, you can finish steel with whatever you want, so you can easily make a Wing blend into an existing building.||20'-50'
Why go with a straight wall building instead of a Quonset hut
The main advantages are aesthetic, since Quonset huts technically offer more in terms of cost-savings and structural stability. Some people simply prefer the traditional style of straight walls and a roof-over-the-arch look. These buildings are still quite sturdy and stable, thanks to their pre-fabricated steel construction.
