Arco Frame Types
FRAME TYPES
METAL BUILDINGS 101: ARCO FRAME SYSTEMS
Either clear span frames or frames with interior columns are available through our metal building supply company. Widths greater than 80 feet are more economical with an interior column. Endwall frames feature a beam and column design, unlike the rigid frame design used on the interior frames of the building, for maximum cost effectiveness. Optional rigid frame endwalls for future expansion may be ordered for the endwalls. All frames are finished with a red oxide primer.
GABLED (CLEAR SPAN)
A rigid (double slope) building in which the ridge is in the center of the building. Welded plate, tapered column “clear span” system, available in 1:12 or 4:12 roof slope. Standard widths are 20′ to 120′, eave heights of 10′ to 25′, and bay heights of 20′, 25′ or 30′. Greater widths and eave heights may be achieved, but must go through Design prior to quoting.
For projects requiring uninterrupted interior space, this Arco frame type is an ideal choice for maximizing usable square footage. This makes them perfect for recreational facilities, manufacturing plants, and aircraft hangars, where open layouts are essential. Additionally, these frames reduce the need for interior support structures, helping optimize flexibility in layout design.
GABLED (WITH INTERIOR COLUMNS)
Gabled (with interior columns) A ridged (double slope) building in which the ridge is in the center of the building. A modular, tapered column system, available in widths of 80′ to 240′, with eave heights of 12′ to 25′ and standard bay lengths of 20′, 25′ or 30′. Roof slope is 1:12. Greater building widths may utilize more than one row of interior columns to reduce cost.SINGLE-SLOPE
A sloping roof in one plane with both high sidewall and low sidewall columns. The slope is from one wall to the opposite wall. These are typically used for strip malls/shopping centers and office complexes. Façades or parapet walls are commonly used to give the appearance that all four walls are the same height. Single-slope buildings are also used when adding on to an existing building in the event that it was not designed to carry the load of a lean-to.
Single-slope structures offer flexibility for phased development. By selecting this design, businesses can ensure easy integration with future expansions. These pre-engineered metal buildings also support energy-efficient designs, as the roof slope allows for better water drainage and provides an excellent surface for solar panel installations.
LEAN-TO
Perfect for providing you with that extra storage space you need alongside your building. The Lean-to ties in at the eave of another building or below the eave and can provide a variety of uses, from just a covered area to a completely enclosed addition to your building. Available in all width extension increments for all new structures. The maximum width and height dimensions will vary according to loading requirements. Inside clearances can be specified for all frame options.
Whether used as a sheltered walkway, supplementary warehouse space, or even a utility work area, lean-tos are an Arco frame type that’s economical and adaptable. Their flexible configurations ensure you get just the right amount of space for your specific needs while maintaining a cohesive appearance with the main building.
