Abstract
An elongated metal structural member including an expanded metal web formed by severing a metal strip along a sinuous path forming a plurality of keystone-shaped tabs on each half, moving the two halves directly away from each other until outer corners of the tabs of one half overlap outer corners of the tabs of the other half, and affixing together the outer corners of one half with outer corners of the other half.

A metal structural member comprising an elongated web, said web including two substantially straight identical halves, each of said halves having a plurality of outwardly extending spaced tabs and said tabs of said identical halves being identical, each of said tabs having an outer edge and said outer edges of adjacent tabs being separated by a gap, said outer edge being wider than said gap between said adjacent tabs, said tabs further having side edges, each side edge and outer edge of each tab forming a corner, said corners of one of said two halves overlapping said corners of the other of said two halves and said overlapping corners being in separate parallel planes, and said overlapping corners being rigidly affixed together to form an expanded web.
A metal structural member comprising an elongated web, said web including two substantially identical halves, each of said halves having a plurality of outwardly extending spaced tabs, each of said tabs having an outer edge and said outer edges of adjacent tabs being separated by a gap, said outer edge being wider than said gap between said adjacent tabs, said tabs further having side edges, each side edge and outer edge of each tab forming a corner, said corners of said two halves being rigidly affixed together to form an expanded web, said corners being affixed together by reverse bends along said outer edges, said reverse bends of one of said halves grasping therein said reverse bends of the other of said halves, with said reverse bends being tightly crimped.
