Residential Floor Span Charts
- Up to 12" may be field-trimmed from each end of the SpaceJoist TE truss. Contact your SpaceJoist TE representative or Engineering Department prior to any additional trimming.
- Span charts reflect the benefit of composite action afforded by a glued-nailed or glued-screwed connection of the sheathing to the top chord of the truss. Consult your SpaceJoist TE representative for appropriate spans if a nailed-only or screwed-only connection is to be utilized.
- Span dimensions are out-to-out at bearing supports.
- Minimum required bearing length is 1-3/4".
- Span charts are for the uniformly loaded conditions specified in the heading of each chart.
- For SpaceJoist TE trusses supporting concentrated (point) loads, cantilevered end conditions, or other special loading conditions, contact your SpaceJoist TE representative.
- Some spans may require top chord supports and/or web stiffeners. Contact SpaceJoist TE engineering for required reinforcements.
- Span Charts for additional loadings are available from your SpaceJoist TE representative.
