Shop Fabricated Wood Trusses

Use this 3 part specification template to specify pre-engineered, shop fabricated wood trusses for floor and roof framing.

Trusses play a crucial role in modern construction, providing structural support and stability to roofs, floors, and bridges. Understanding the process of truss fabrication and installation is essential for architects, builders, and homeowners alike. In this guide, we’ll delve into the intricacies of truss fabrication, highlighting its importance and key components.

The Fabrication Process

Trusses are commonly fabricated in off-site facilities, also known as truss manufacturing plants or truss plants. This prefabrication process offers numerous benefits, including increased efficiency, precision, and quality control. Fabricating trusses off-site allows for optimal working conditions and specialized equipment, ensuring that each truss meets rigorous industry standards.

Materials Used in Truss Fabrication

Trusses are typically constructed from dimensional lumber, such as timber or engineered wood products, chosen for their strength, durability, and cost-effectiveness. Steel connector plates and plywood gussets are often used to join the lumber components, providing additional reinforcement and structural integrity. These components are carefully selected and assembled to create trusses tailored to specific project requirements.

Transportation and Installation

Once fabricated, trusses are transported to the project site for installation. This transportation phase requires careful planning and coordination to ensure the trusses arrive safely and on schedule. Specialized vehicles, such as flatbed trucks or trailers, are used to transport trusses, with each truss securely fastened to prevent damage during transit.

Precision Installation Techniques

Truss installation is a critical phase of the construction process, requiring precision and attention to detail. Trusses are lifted into position using cranes or other lifting equipment, then secured in place according to engineered specifications. Proper alignment and bracing are essential to ensure the structural integrity of the truss system and the overall stability of the building.
