What type of gusset plates are used on wood or floor trusses?

The correct answer highlights that gusset plates used on wood or floor trusses can either be made of plywood or metal. Plywood is a popular choice because it is strong, lightweight, and can be easily cut and shaped to fit various truss designs. Additionally, plywood provides a good surface area for fastening and can effectively distribute loads across the truss members.

Metal gusset plates are also commonly used due to their superior strength and durability compared to wood options. They tend to provide a more rigid connection and can handle heavier loads, making them especially beneficial in structural applications.

The other materials, like acrylic, laminated polymer, and organic adhesion board, are not typically utilized for gusset plates in truss construction. Acrylic is a plastic that lacks the necessary strength for structural applications, while laminated polymer does not provide the same level of support and stability that plywood and metal offer. Organic adhesion boards can also lack the durability and structural integrity needed for truss applications. Thus, plywood and metal are the most suitable and commonly used materials for gusset plates in wood or floor trusses.
