Partition stud

Abstract

A metal stud comprising a web and flanges extending perpendicularly from respective edges of the web and each having a stiffening return, the web comprising a longitudinal rib at each edge thereof, each rib having a width of 0.250″ from a respective edge of the web and a depth of 0.060″ from a baseline of the web.

What is claimed is: 
     
         1 . A metal stud, comprising a web and flanges extending perpendicularly from respective edges of the web and each having a stiffening return, the web comprising a longitudinal rib at each edge thereof, each rib having a width of 0.250″ from a respective edge of the web and a depth of 0.060″ from a baseline of the web. 
     
     
         2 . The metal stud of  claim 1 , formed from a metal sheet. 
     
     
         3 . The metal stud of  claim 1 , formed from a sheet of a metal having a yield strengths of 33 ksi or 50 ksi with a thickness of 0.017″ or 0.021″ respectively. 
     
     
         4 . The metal stud of  claim 1 , formed from a sheet of a material having a yield strength of 33 ksi or 50 ksi with a thickness of 0.017″ or 0.021″ respectively, wherein said flanges have a width of 1″¼ and said returns have a width of ¼″. 
     
     
         5 . The metal stud of  claim 1 , formed from a sheet of a material having a yield strength of 33 ksi or 50 ksi with a thickness of 0.017″ or 0.021″ respectively, wherein said material is a steel. 
     
     
         6 . The metal stud of  claim 1 , formed from a sheet of a material having a yield strength of 33 ksi or 50 ksi with a thickness of 0.017″ or 0.021″ respectively, wherein said material is a steel comprising an anticorrosion coating. 
     
     
         7 . The metal stud of  claim 1 , said web having a width of 1.625′″, 2.500′″, 3.625′″, 4.000′″ or 6.000′″. 
     
     
         8 . The metal stud of  claim 1 , formed from a sheet of a material having a yield strength of 33 ksi or 50 ksi with a thickness of 0.017″ or 0.021″ respectively, wherein said flanges have a width of 1″¼, said returns have a width of ¼″ and a radius of curvature at a junction between the web and each flange is 0.040″. 
     
     
         9 . The metal stud of  claim 1 , wherein a connecting angle between each rib and the baseline of the web is about 45 degrees. 
     
     
         10 . The metal stud of  claim 1 , wherein the flanges are provided with knurling. 
     
     
         11 . A method for making a metal stud from a sheet of metal, comprising forming a longitudinal rib at each edge of the sheet, and folding the sheet into a general-shape section, with a central web connected at each edge thereof to a flange, and provided with a longitudinal rib at each edge of the central web. 
     
     
         12 . A method for reinforcing a metal stud comprising a web and flanges extending perpendicularly from respective edges of the web, said method comprising providing a longitudinal rib at each edge of the web, each rib having a width of 0.250″ from a respective edge of the web and a depth of 0.060″ from a baseline of the web.
