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

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:

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.”

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.
