There are some major differences in the type of steel buildings available on the market today. Most commercial and agricultural grade buildings come in two main designs. The choice is between arch style and rigid frame steel buildings.
Arch style steel buildings are also more commonly known as Quonset huts. They are built from a series of interlocking metal ribs that take form as the roof and sides of the structure. Arch buildings are used in a variety of applications but are very popularly used as storage facilities, garages of all sizes, and storage sheds. The smaller variety of arch buildings are popular among consumers who choose to build their own structure. This is because the assembly methods are simple and they are less expensive per square foot to construct than more conventional methods. They are, however, difficult to customize with exterior options. This type of construction only allows for doors and windows in the end walls, but not the sides, as a number of consumers would want. The interior overhead clearance of an arch style building drops precipitously as you move further away from the center of the building to the sides.
A more popular form of building for almost any use is the rigid frame style of building. They are constructed using steel skeleton framing and flat steel panels for both the roof and walls. Doors and windows can be added in the side or end walls. Rigid frame buildings are easily expandable lengthwise if future conditions demand. A rigid frame building can also incorporate a mezzanine for second story capacity. They are much easier to build than traditional construction but they require more construction experience and equipment than arch style buildings.
Whether you choose an arch style building or a rigid frame structure a concrete foundation is strongly recommended. The inclusion of a basement is an option but does make the project that much more complicated.
Whatever type of steel building you choose there is an approval process that is necessary. The building codes that will apply to your project vary state by state, and city by city. This includes such factors as snow and wind loads, seismic considerations, and other local considerations. Other things to consider will include your local zoning ordinances, drainage requirements, local community covenants, among others. A quality steel building manufacturer can help your building to meet or exceed your local codes, however, it is ultimately the consumer’s responsibility to get the proper approvals.
Make sure you investigate all of the advantages and disadvantages with both types of buildings before purchasing your structure. Do not place a deposit on a building or do an outright purchase unless you are sure of the style that you want.
