Pre-Fabricated, Pre-engineered Steel Building Structural Framework Designs

There are three major steel structure framework styles to consider when planning your pre-fabricated, pre-engineered steel building venture: clear span, modular, or single slope. Pre-engineered steel structure system sellers and fabricators use a precise planning and pricing process whether you are buying a finished product by phone or via the internet, regardless of which building style you choose. The following information should help you determine the best approach for your project.
The most popular choice on the pre-engineered steel building market right now is the wide span (also called clear span or free span) rigid framework structure. This design is the perfect solution when you need a large, unobstructed interior space. A clear span rigid steel frame structure is economical to build, provides dependability and durability, and is also adaptable to any configuration. There are no inner load-bearing column supports needed, so this system it is often used for industrial facilities, stores, sports facilities, farm and ranch structures. The interior can easily be divided using partitions into offices, rooms and other private areas. Since these internal partitions are non-load bearing, you can reposition your floor design as needed. Clear span construction is extremely cost effective for structures up to 150 feet wide. For structure widths over 150 feet wide up to the maximum available width of 300 feet, the cost per square foot will increase due to the fact that the structural framework must be made sturdier to handle the increased load caused by the broad distance.
The second category is the modular structural framework. Unlike clear span construction, modular steel building frames use interior load bearing pillars. The use of inner supports generally decreases the cost of both the framework and foundation, as loads are distributed more evenly. Modular design works well for an all-steel structure or plant that needs moderate interior space. The cost savings over clear span are most significant for structures up to about 80 feet across, but building widths up to 150 feet can also be economically feasible. Structures greater than 150 feet wide will usually include inside supports, unless the planned use of the building justifies the extra expense of clear span.
The single slope frame is the third style of pre-fabricated steel building. These structures have a distinctive appearance, since they have varying eave heights on each building sidewall. The rooftop pitches up from the front of the structure all the way to the back. Since the eave height of the lower side is generally pre-determined, you’ll need to calculate the appropriate slope for the roof. Roof slope is the quantity of inches a steel roof ascends vertically for each 12 inches of horizontal length. Although they can be more steeply pitched, a lot of single sloped building roofs employ one-half on twelve pitches. Strip malls, office suite areas, as well as mini-storages often employ the single slope engineering.
Think carefully about how your building will be used, and talk to your qualified steel building manufacturer or supplier to determine which building is the best selection for your project.
