Request Information
The HDS® Framing System is a high-performance, cost-effective, multipurpose, heavy-duty framing stud for headers, jambs, posts and built-up tube truss chords and webs. The superior strength and carrying capacity of the HDS® Framing System means higher performance with fewer members. It means eliminating box beam headers, nesting track and stud for posts and jambs, and eliminating multi-member built-up truss chords and webs. It also means improved finish quality by eliminating excessive material and screw head buildup around doors and windows.

Note

Note

 N/A Standard material coating is CP60 per ASTM C955; G90 available.
  • 1 For members having a web depth of less than 8" and also having a thickness less than 97 mil, allowable web crippling per AISI Standard for CFS Wall Stud Design 2004. This value assumes the web resists web crippling and the HDS is nested in track having the same thickness. For other members, allowable end one flange web crippling per AISI NASPEC, 2001 with 2004 supplement. Both calculation procedures use a bearing length of 1-1/4".
  • 2 Allowable end one flange web crippling per AISI NASPEC, 2001 w/2004 supplement. This value assumes 2 flanges resist web crippling for a bearing length of 1-1/4".
