Blog circa Repurposed Poultry Barn Trusses Cut Construction Costs

For those seeking an economical yet sturdy construction solution for warehouses, workshops, or agricultural buildings, an unconventional option has emerged: repurposed steel trusses from decommissioned poultry barns. These structural elements, originally designed to support large-scale farming operations, now present a compelling opportunity for secondary use in various construction projects.

Engineered to bear specific loads, these steel trusses can be professionally evaluated and adapted to serve as structural frameworks for buildings spanning 32 feet or more. Early adopters have successfully transformed these components into spacious, well-lit industrial facilities while significantly reducing construction costs.

The appeal of poultry barn trusses extends beyond cost savings. Their structural integrity remains a key advantage, as they were originally designed to withstand substantial uniform loads. For example, a 32-foot span truss can typically be spaced at 10-foot intervals and supported by 6x8 inch posts, demonstrating excellent performance in various applications.

One builder reported using 36-foot trusses to construct a 60-foot-long workshop. The trusses were anchored to concrete posts to achieve a 12-foot clearance, with purlins welded to support metal roofing and siding. Another successful project involved 30-foot trusses spaced 12 feet apart to create a 30x36-foot barn, utilizing 2x6 wooden purlins to achieve an open interior with generous ceiling height.

Critical to these projects is the secure connection between trusses and supporting structures, typically achieved through welding or bolting at the bottom flange or nodal points. While connection methods vary based on design specifics, the principle remains consistent: ensuring robust load transfer to supporting elements.

While offering significant benefits, repurposed trusses require careful evaluation:

• Structural assessment: Original load specifications must be verified, particularly for regions with snow accumulation requirements. Professional engineering consultation is recommended.
• Handling logistics: Large trusses often require specialized equipment for transportation and installation.
• Connection engineering: Proper detailing of connections to posts or foundations is essential for structural integrity.
• Corrosion protection: Existing rust may necessitate surface treatment to ensure longevity.

The ongoing modernization of poultry operations has created a steady supply of used trusses, with some available for as little as $50 per unit. However, past incidents of structural failures in high-snow regions underscore the importance of thorough engineering evaluation before repurposing.

Recent reports of poultry barn collapses in Delaware and Maryland due to snow accumulation have increased market availability while simultaneously highlighting the need for rigorous structural assessment.

When properly evaluated and installed, these repurposed trusses offer an environmentally conscious and cost-effective alternative for construction projects, combining historical durability with contemporary utility.
