Selkirk Truss manufactures floor trusses, fully customized to the customer’s needs, up to 22″ deep. Manufactured floor trusses are sometimes referred to as ‘open web floors’ or ‘System 42’ trusses because to build them we turn the 2×4’s on their side. This allows for shallow depths as well as a 3-½” nailing surface. A manufactured truss is an engineered structural component assembled from wood members, metal connector plates and other mechanical fasteners. The truss members form a rigid structural framework and are assembled such that the members form triangles. Most architects and builders are familiar with roof truss systems but may not realize the advantages of a manufactured floor truss system.
Advantages in Design:
- Floor trusses can span great distances, creating larger open spaces below, unobstructed by columns and partitions.
- HVAC, electrical, plumbing, and even beams can be run through the open webs requiring no dropped ceiling to conceal ductwork, which can make rooms feel smaller.
- Truss systems are quicker and easier to install than traditional floor joists, and because they’re manufactured in controlled environments, there’s less chance of warping, shrinking, and twisting of lumber.
- Manufactured floor truss systems also save timber resources by reducing the amount of wood waste generated during construction.
Advantages in Installation:
- The open web design allows for utilities to be run through in the floor system without drilling or cutting holes.
- Electricians, HVAC contractors and plumbers are off the job quicker.
- The consistent size and height of the manufactured floor joist makes sub-floor material installation easier.
- No cutting or fitting is required. Strong, lightweight, and rigid, ‘System 42’ Floor Trusses go up easily and quickly. Often without the use of a crane.
- Decking and ceiling materials are attached directly to trusses without need for special hardware.
- These benefits will reduce the amount of time trade contractors spend on site, speed up construction, and ultimately save the customer money.
