Post-Frame Construction

Choosing the Right Truss System

2025-03-23Updated: 2025-04-21 Valley Truss

Post-frame construction has risen in popularity throughout Colorado for its versatility, cost-effectiveness, and impressive clear-span capabilities. At the heart of every successful post-frame building is a properly designed truss system that ensures structural integrity while meeting the specific needs of your project. As the exclusive truss provider for Post Frame Plus in Penrose, Valley Truss combines engineering expertise with manufacturing excellence to deliver truss systems specifically optimized for post-frame applications.

Whether you're planning a barndominium, workshop, agricultural building, or commercial space, understanding your truss options is essential for a successful build.


Understanding Post-Frame Construction Basics

Post-frame construction utilizes large posts or poles buried in the ground or mounted on concrete foundations to provide the primary structural support for the building. This method creates a framework where the load is transferred directly from the roof to the posts and into the ground, eliminating the need for interior load-bearing walls.

  • Structural Support
    Unlike traditional stick-frame construction that uses closely spaced studs on a continuous foundation, post-frame buildings feature posts typically spaced 8' apart, creating wider spans between structural supports.

  • Open Interior Space
    The result is an open, flexible interior space that can be configured to suit virtually any purpose, from workshops to living spaces.

  • Versatile Applications
    Post-frame buildings are ideal for a variety of applications in Colorado, from agricultural structures and workshops to the increasingly popular barndominiums.


Truss Considerations Specific to Post-Frame Buildings

When designing trusses for post-frame construction, several factors must be considered to ensure optimal performance in these specialized structures:

  • Wider Spacing Requirements
    Unlike traditional construction where trusses are typically spaced 24" on center, post-frame buildings generally use trusses spaced at 4' on center to align with post placement. This wider spacing means each truss must be designed to handle significantly more load.

  • Load Transfer Mechanisms
    In post-frame buildings, the entire roof load is transferred to the posts through the truss-to-post connection. This connection point requires careful engineering and often specialized hardware to ensure proper load distribution.

  • Clear-Span Capabilities
    One of the primary advantages of post-frame construction is the ability to create large, open interior spaces. Trusses must be designed to span these distances (up to 90 feet with Valley Truss) without intermediate support while maintaining structural integrity.

  • Colorado Climate Considerations
    Colorado's variable climate presents unique challenges, with heavy snow loads in mountain regions and high wind areas along the eastern plains. Trusses must be engineered to handle these specific regional conditions, which vary significantly across the state.


Types of Trusses for Post-Frame Buildings

Valley Truss manufactures several truss types specifically designed for post-frame applications, each offering unique benefits for different project requirements:

  • Clearspan Trusses
    These trusses provide maximum interior space with no interior supports, making them ideal for workshops, equipment storage, and open concept barndominiums. Our manufacturing capabilities allow us to produce clearspan trusses up to 90 feet wide, accommodating even the largest post-frame projects.

  • Attic Trusses
    For buildings where additional storage or future living space is desired, attic trusses create usable space within the roof structure. These are popular choices for barndominiums and workshops where overhead storage is valuable.

  • Mono-Pitch Trusses
    These single-slope trusses are perfect for lean-to additions or buildings where a simple drainage system is preferred. They're commonly used in agricultural applications or as additions to existing structures.

  • Scissor Trusses
    When vaulted ceilings are desired for aesthetic appeal or improved ventilation, scissor trusses provide the perfect solution. These trusses create dramatic interior spaces while maintaining structural integrity.

  • Gambrel Trusses
    For a traditional barn look with maximum overhead space, gambrel trusses create the distinctive two-slope design on each side. These trusses provide excellent storage capacity and a classic agricultural aesthetic.


Factors to Consider When Selecting Your Truss System

When working with Post Frame Plus and Valley Truss on your post-frame project, consider these important factors in your truss selection:

  • Building Use and Interior Space
    How you plan to use your building will significantly impact your truss choice. Need maximum overhead clearance for equipment? Clearspan trusses might be best. Planning a barndominium with living space above? Attic trusses could be the right solution.

  • Local Climate Conditions
    Colorado's diverse climate means snow loads and wind requirements vary dramatically by location. Our engineering team at Valley Truss designs each truss package with your specific location in mind, ensuring compliance with all local building codes.

  • Budget Considerations
    Different truss designs come with different price points. We'll work with you to balance performance with cost-effectiveness, finding the right solution for your budget without compromising structural integrity.

  • Aesthetic Goals
    The truss style you choose impacts both the exterior appearance and interior feel of your building. From classic gambrel designs to modern scissor trusses, your selection contributes significantly to the character of your finished structure.

  • Future Expansion
    Planning for potential future additions now can save considerable costs later. Our engineering team can design your truss system with future expansion in mind, ensuring your building can grow with your needs.
