"stran steel studs" on 1948 drawings. any info?
does anyone have a catalog or other info on "4 inch stran steel studs @ 16" c.c."? this is the callout on some 1948 drawings for a building that we are rehabbing. in this particular case they are load bearing wall studs supporting a bar joist roof system. thanks for the help.
its not much, but i've run across this.
