Product Information

Precast/Prestressed beam depths will vary based on the specific project design.  Common beam shapes are Inverted Tee, L-Shaped and rectangle profiles.  Prestressed beams are typically supported by columns and used for to support double tee, hollowcore or solid slab framing.

Standard Design Options

  • Prestressed beams can be used to support other framing systems (CLT) given their structural ability for longer spans.
