I'm just going over a report and there is reference to a W25x100. The time period would be the late 1970's and in Canada. Has anyone come across this 'critter'... I've not been able to obtain any information about the section.
That was my thought... It's only referenced the one time... but, there is no other reference to a W24x100 either... my 1962 steel handbook has a 24WF100 listed.
