Hi all,

I repair a number of low income rental properties. In recent years we've
experienced an uptick in tenant violence towards the rental units. We
are getting interior door "holed" and mangled and main entry doors are
getting kicked in and the hinges occasionally get bent (maybe swinging on
the door?).

We've been replacing the kicked-in entry doors with the "steel" doors at
Lowes and Home Depot. Unfortunately, these light duty doors simply
aren't strong enough.

Anyone know of an industrial strength steel door for reasonable dollars?
