16 . The cold formed metal stud of claim 1 , said first flange forming an acute angle with said web.
17 . The cold formed metal stud of claim 1 , said second flange forming an obtuse angle with said web.
18 . The cold formed metal stud of claim 1 , said second flange forming an acute angle with said web.
19 . The cold formed metal stud of claim 1 , said second flange further comprising a vertically extending second channel.
20 . The cold formed metal stud of claim 19 , said second channel having a dovetail shaped cross-sectional profile.
21 . The cold formed metal stud of claim 19 , said second channel having a plurality of channel perforations.
22 . The cold formed metal stud of claim 19 , said second channel having a plurality of channel indentations.
23 . The cold formed metal stud of claim 1 , said second flange further comprising an end flange.
24 . A method of forming a composite panel assembly, the method comprising the steps of:
pouring a concrete panel; and,
embedding a first flange portion of a cold formed metal stud in said concrete panel, said first flange portion located along a first longitudinal edge of a vertically extending web of said cold formed metal stud
wherein when said concrete panel solidifies said cold formed metal stud and said concrete panel form a composite panel assembly.
25 . A method of manufacturing a cold formed metal stud, the method comprising the steps of:
forming a first flange portion along a first longitudinal edge of a vertically extending web;
forming a second flange portion along a second longitudinal edge of said vertically extending web; and
forming a vertically extending channel along said first flange portion.
26 . The method of claim 25 , the method further comprising the step of:
forming at least one channel perforation in said vertically extending channel.
27 . The method of claim 25 , the method further comprising the step of:
forming at least one channel indentation in said vertically extending channel.
28 . The method of claim 25 , the method further comprising the step of:
forming at least one web opening along the centerline of said web.
29 . The method of claim 28 , wherein said at least one web opening is elliptically shaped.
30 . The method of claim 28 , the method further comprising the step of:
forming a stiffening rim around the perimeter of said at least one web opening.
31 . The method of claim 25 , the method further comprising the step of:
forming at least one longitudinally extending stiffening rib in said web.
32 . The method of claim 25 , the method further comprising the step of:
forming at least one indentation in said web.
33 . The method of claim 25 the method further comprising the step of:
forming an end flange in said first flange portion.
34 . The method of claim 25 the method further comprising the step of:
forming a vertically extending second channel in said second flange portion.
35 . The method of claim 34 , the method further comprising the step of:
forming at least one channel perforation in said vertically extending second channel.
36 . The method of claim 34 , the method further comprising the step of:
forming at least one channel indentation in said vertically extending second channel.
37 . The method of claim 25 , further comprising the step of:
forming an end flange in said second flange portion.
