It's the galvanised ones I grew up with. Are _any_ of them good
long term? Andy
Houses in the 50s were built with em, Houses in the 50s still
standing :-)

Yep and they probably will be for another 100 years or so.
Galvanised ones aren't sold anymore AFAIK due to them not meeting building
regs, although there are probably several hundred million still knocking
about in people's sheds etc.
Stainless ones are fairly cheap nowadays anyway

The ties in my house built in 1925 are starting to fail. Main problem is
that the tails are swelling with rust and forcing the bricks apart.
The problem is exacerbated by high porosity handmade bricks.
Lime mortar was used in those days so the wall will have to be rebuilt
in the next few years. I've no idea if they are galvanised or plain
steel from that era. Still 85 years is not too bad!
