Freezing Pipes?

I've had copper domestic plumbing pipes freeze and rupture. Always when they were installed in an exterior wall.

My hydronic heating system is full of steel pipes, some in exterior walls. Never a freezing problem in 60 years. Is it because steel is stronger and resists bursting?

Yes... steel is stronger than copper but it is not immune to bursting.
If it freezes solid..... it can burst too.

Thanks. My typically vacant bedrooms have manual control valves on their heat emitters. I leave them cracked open, which probably has helped prevent freezing.
