Typical Steel Building Basic Framing Components
Steel Building Main Frame Styles
The Gable Framing System is the most common building frame type. The frame is designed to accommodate all types of steel building applications. A Gable Frame can reach clear-span widths from ten feet up to two hundred feet and roof pitches up to 12:12*.
The Single Slope Framing Style is a good option for adding on to an existing building or for use as a stand-alone building with a slanted roof. The Single Slope design is extremely versatile and provides flexibility in the design of your building or addition. Water can be controlled by draining off the low side and gutters and downspouts are not needed for high side elevations.
When on a budget and not necessarily needing a clear interior, a multi-span steel building is a viable option. If the building width exceeds 75’ then including interior support columns can help to support the long spans and larger roof loads thus further saving on cost.
With a traditional barn look in mind, the Monitor framed building is used in today’s market for a variety of purposes. What was once used mainly for agricultural buildings, the monitor building is growing in popularity for houses, workshops, warehouses and other commercial buildings. The structural integrity of Steel Structures Unlimited’s pre-engineered steel buildings make unobstructed interiors like the monitor possible.
Ideal for residential structures or buildings with an upstairs office area, the Multi-Story steel building with a Mezzanine is an excellent solution to make the most out of your space. By using a combination of I-Beams, open web bar joists and columns to support the floor, this building frame style can provide endless design options.
To maximize natural light or air circulation, a clerestory roof is superior solution. With a vertical wall splitting the two sloping roofs, a row of windows or one continuous window is easily incorporated. High above the rest of the steel building, the clerestory reaches the most sunlight while preserving privacy.
A Lean-to Frame can be added onto an existing building structure to provide a parking area, outdoor storage or a covered porch. Lean-tos have a similar looking appearance to a single-slope frame but are usually smaller and used only as building additions. Lean-tos are typically attached to an adjoining column. Lean-tos are not stand-alone buildings.
The straight column frame is primarily used to create an unobstructed interior space. With strength and stability maximized in the straight columns of the steel frames, the design is ideal for garages, offices or other commercial purposes.
Also similar to a traditional barn structure, the gambrel style roof provides a spacious building that is both visually appealing and fully-functional. The gambrel style can conveniently incorporate your storage needs with a second floor or loft.
