I don't think anyone is arguing with that. Any item that
fails in normal service is either not properly designed,
or not properly built.
However, aluminum IS much more subject to work hardening
than steel, and that fact must be taken into account during
the design process.
And when it IS taken into account, the product, when considering
structural products like towers, ends up being very much more
expensive than the comparable steel item.
Disagree?
