Typical of that website- - - - -misinformation, presented in a very convincing manner, which can get a newbie into serious trouble. There's a lot of tall buildings from the early 1900's with structural steel skeletons that were assembled with properly done hot rivets that are still standing strong. The whole rivet was heated cherry red, then tossed to the assembly team. Repeat as required, thousands of times!
