The set we know and loved as the SGC, including the Gate room, briefing room, mess, infirmary, nondescript hallways, and more, was eventually torn down. Parts of the actual Stargate were auctioned off soon after. This set was used for a few more Atlantis episodes (Midway and Search and Rescue) while it was being used for filming Ark of Truth and Continuum.
