24’x40’x12′ Single-Slope Pole Barn Kit with Open Front

This 24x40x12 single-slope pole barn kit is designed for open-front access and long-lasting durability—ideal for equipment storage, agricultural needs, or sheltered workspace. The materials package includes everything required to build a structurally sound building with a modern single-slope roof profile.

The structural framework is built around 3-ply 2×6 glu-laminated posts spaced 8 feet on center, with pressure-treated 6×6 posts placed every 20 feet along the open front wall for enhanced stability. Each post sits atop a precast concrete footer block (5×12 standard, 5×16 on the open wall) and is anchored with an 80 lb bag of Sakrete per footing.

Headers include 2-ply 2×10 Southern Yellow Pine across standard walls, and a stronger 2-ply 16″ LVL header on the open wall for added structural support. The roof system uses pre-fabricated parallel chord trusses on a 4/12 pitch, spaced 48″ apart, engineered for 30-5-5 loading.

The barn features 12-inch eave overhangs with vented metal soffits, flush gables for a clean profile, and a 2×8 pressure-treated skirt board for ground-level protection. Horizontal framing includes 2×4 girts and roof purlins spaced 24 inches on center.

Everlast’s 28-gauge LYNX Series metal roofing and siding deliver superior weather protection and aesthetic appeal. Ventilation is enhanced with vented closures under the peak trim, and all trim components—peak, rake, corners, base angle, gutter apron, and overhead door trim—are painted steel for a polished, finished look. The package includes 4-inch GRK structural screws for secure header installation.
