Update: Here are the doors, installed.
ReUse Action and Rusted Grain can manufacture a variety of projects from reclaimed materials. These doors look great on the garage, but also would accent a room in a loft apartment or hous hold when installed as a sliding door (surface mounted). You’d have a attention grabber that would accent a room when it’s both opened and closed.
Costs vary depending on size and style, interior or exterior applications, and level of finish.
