Standard Truss Configurations - Factory Builders

Open Joist™ floor trusses are "stock" trusses built to standardized configurations determined by truss depth and length. Engineering fits these standard trusses into specific job situations by matching truss depth, on-center spacing and other factors to residential floor loadings and other requirements.

Actual profiles for standard OPEN JOIST trusses are also shown below.
