Pre-engineered steel building frameworks are available in many varieties, so it is very important to study the all of the styles available before settling on a particular framework for your building. Commercial and agricultural grade all-steel structures are offered in two main configurations: rigid frame and arch styles.

Quonset huts are now more commonly known as arch style buildings. These buildings are appropriate for a large array of uses, including agricultural buildings, large and small garages, and storage sheds. The unique shape of the roofing and sidewalls of these steel building are created by the utilization of a series of interlocking metal ribs. Because arch style buildings are so simple to assemble, they are chosen by many buyers who want to construct their own building. They can cost a fraction of the amount for a conventionally built structure. Doors and windows are almost always installed only in the endwalls, because it is very difficult to install them on the arched walls. The overhead clearance towards the sides of the building drops quickly, reducing usable interior space.

Rigid frame design is more commonly used because it can be implemented for a wide assortment of needs. With sufficient building height, inclusion of a second level or mezzanine in a rigid frame pre-engineered structure is possible. While they do require more experience and equipment than arch systems, rigid frame steel structures are easier to assemble than traditional construction. Windows and doors can be added to the side or end walls. It is a favorite framework option because it incorporates high-grade steel skeleton framing as well as flat steel panels for the roof and building walls. Easy expansion of the pre-engineered steel structure down the road is feasible with this solid framework.

Regardless of structure style, you’ll need to obtain building approval. The ordinances that pertain to your project vary from state to state, and even from city to city. Proper wind and snow loads, earthquake (or seismic) activity opposition, and all other area conditions are addressed by local regulations. Zoning codes, rain drainage requirements and city or county covenants are other issues that can affect your project. A competent steel building producer or provider can help design your building to meet or exceed any structural codes. It is, however, the buyer’s responsibility to obtain the proper approvals.

You can include a basement with either style, but it will considerably increase the cost and complexity of your building project. Concrete pads are strongly recommended as a foundation regardless of whether you choose an arched structure or a rigid frame configuration.
Until you are absolutely certain of the building style you want, do not even make a down payment. Thoroughly research the two building styles to determine the right approach for your project before you buy.
