Queen Post Roof Truss

Custom Wood Trusses for Stunning Architectural Ceilings

Longer Spans. Balanced Strength. Proven Structural Design.

A queen post roof truss builds on the simplicity of the king post design while allowing for longer, more stable roof spans. By using two vertical posts instead of one, this truss distributes loads more evenly and reduces stress across the bottom chord.

At Allied Truss, queen post trusses are fully engineered structural systems—not off-the-shelf layouts. Each truss is designed for your specific span, roof pitch, loading requirements, and building application, then manufactured in-house for consistency and performance.

This design is ideal when a king post truss isn’t quite enough—but a more complex truss system isn’t necessary.

Why Builders Choose Queen Post Roof Trusses from Allied Truss Company

Custom Truss Design, Not Stock Layouts

Every project has different roof pitches, loads, and bearing conditions. We custom-design each queen post truss to match your plans.

Efficient Framing Without Overcomplication

Builders appreciate queen post trusses because they offer increased span capability without the clutter of heavy webbing. Our truss designs keep framing clean and easy to work with during installation.

Manufactured for Jobsite Accuracy

Trusses are fabricated in-house using consistent lumber selection, precise cuts, and proper connector placement. That accuracy means faster installs, fewer field adjustments, and smoother inspections.

Texas-Based Reliability

With local engineering, manufacturing, and delivery, Allied Truss keeps communication tight and timelines realistic. Builders across Texas rely on us to deliver trusses that arrive ready to set and perform exactly as designed.

When a Queen Post Truss Is the Right Fit

Queen post trusses are commonly used for:

  • Residential homes with wider footprints
  • Garages and detached structures with broader bays
  • Agricultural buildings and barns
  • Workshops and storage facilities
  • Light commercial buildings

If your project requires even longer spans or open vaulted interiors, we’ll help you find the best truss type. If a queen post truss fits, we’ll engineer it to perform.

How a Queen Post Roof Truss Works

A queen post truss features two vertical posts (queen posts) positioned symmetrically along the bottom chord, connected by a horizontal straining beam near the top.

This configuration:

  • Shortens unsupported chord lengths
  • Reduces bending stress in the bottom chord
  • Improves stability across wider spans
  • Creates a more balanced load path

While visually similar to a king post truss, the structural behavior is very different. Proper engineering is critical to ensure the queen posts, straining beam, and chord connections work together as a single system.
