People often call us asking how they can tell if a piano has an iron frame. There are 4 easy steps that can be followed to tell you if a piano has an iron frame rather than a wooden frame. These are as follows:
1. With the top lid open, look down inside the piano.
2. Whilst looking down inside the piano and looking at the back section, you should see approximately 250 tuning pins exiting the tuning plank.
3. Have a look around the tuning pins, if you can see or feel a metal structure running the length of the piano (Usually a gold colour) around the tuning pins, the piano has an iron frame.
4. If there is no metal structure around the tuning pins, the piano is most likely a wooden framed piano and may not be tunable.
