If coarse, furrowed bark, with deep fissures is what you want, along with cold hardy, you really need to look at the bur oak.
Super cold hardy and very rough bark. Hardy through or at least into zone 3.
Only the cork oak has a more rugged bark, and the cork oak is a tender mediterranean tree that will not tolerate its roots freezing solid.
