Floor Cassettes

Our flagship product — prefabricated floor systems built with factory-controlled precision. We are not limited to standard dimensions. 100% of what we do is custom.

Specifications

Typical Spans12' to 24'+
Depth Options9-1/2" to 16" (I-joist dependent)
Live Load40 PSF residential / 80+ PSF commercial
Dead Load10-15 PSF (assembly dependent)
Sheathing1/2", 5/8", 3/4", 1"+ T&G OSB or plywood
Max Panel Width8' standard (transport width)
Max Panel LengthUp to 60' (per transport limits)

Materials

  • TJI / BCI I-joists (primary joist)
  • LVL rim board and headers
  • Glulam beams (at bearing points)
  • Dimensional lumber blocking
  • Simpson Strong-Tie connectors

Wall Panels

Factory-built wall panels with pre-installed sheathing, delivered ready for crane setting.

Specifications

Wall Heights8', 9', 10', and custom
Stud Sizes2x4, 2x6 (standard)
Stud Spacing16" O.C. or 12" O.C.
Sheathing7/16" or 1/2" OSB (one or two sides)
Max Panel LengthUp to 40' (transport dependent)
Hold-DownsSimpson HDU / PAHD series pre-installed

Materials

  • SPF or Doug Fir studs
  • OSB structural sheathing

  • Pre-installed anchor bolt layout
  • Fire blocking per code

Roof Panels

Prefabricated roof systems that eliminate on-site cutting and dramatically reduce installation time.

Specifications

Pitch RangeFlat (1:12) to 12:12
Rafter Sizes2x6 through 2x12
SpansUp to 24' (rafter dependent)
Sheathing1/2" or 5/8" OSB / plywood
