Product Description
|
SigmaTrak™ is the ideal runner track for load bearing and curtain
wall metal stud wall assemblies. Manufactured from mill-certified steel, SigmaTrak’s
unique shape is designed to allow a stud to seat fully within the track, providing
full bearing at the top and bottom structural tracks. Load bearing studs must be
fully seated within the top and bottom tracks according to design standards.
SigmaTrak™ eliminates field issues typically seen with (T) section
tracks where the studs bear directly on the corner radius of the track, creating
gaps between the stud and track.
|
Load bearing walls are designed to fully seat within the top and bottom tracks.
Standard (T) Section tracks (above left) can contain an inside corner radius that
prevents “full” bearing within the track. SigmaTrak™ (above right)
allows full bearing of the stud within the track
|
|
SigmaTrak™ Value:
- Track web is oversized to allow the stud to seat fully in the track
- Eliminates the gap between the stud and the track as a result of bearing on corner
radii
- Faster assembly than with standard track(no forcing/squeezing stud into bearing
on track radii)
- Manufactured from traceable mill-certified steel
- Manufacturing tolerances based on ASTM C955-06

Track Recommendation
Load bearing studs must be fully seated within the top and bottom track. Design
standards recommend a maximum gap of 1/8” in order to obtain an effective bearing
condition
