Reed's elasticity was stretched to its limits by Doom, iirc. Even in comics, it is not all that effective against physical attacks.
As for Sue's shield - the London Eye was giving her an aneurysm - I don't see it withstanding more than one punch (if that).
Thing is actually quite weak, he struggled a lot to simply pull up a fire-engine and he struggled to support (along with Sue) the London Eye.
Hulk would have no problems with either feat.
