A sheet metal structural shape for use as a stud or mullion in wall construction or a purlin or sub-purlin in deck construction which is symmetrical about a vertical bisecting plane having a central vertical web, two diagonal legs projecting downwardly from one end of the web forming an included angle of about 30.degree. to about 90.degree., each of the diagonal legs having a leg projecting downwardly at its extremity in a plane substantially parallel to the web, each of the parallel legs having flanges extending outwardly at their extremity, a closure side extending between the extremities of the flanges enclosing the area formed by the diagonal sides, parallel sides and closure side, and a stiffening member at the other end of the web. A wall structure utilizing a spaced series of the metal structural shapes with a wall material attached to the flanges of adjacent structural shapes. Also included in this invention is a double wall construction wherein a second wall material is attached between adjacent metal structural shapes to a flat face of the stiffening member of the structural shape.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
