Grand Piano P 237 Monsoon with steel frame

Grand Piano P 237 Monsoon with steel frame was built based on the research and development activities of The PETROF Company in cooperation with Universities, science institutions and special metal workshop. The core idea was the replacement of the cast iron frame (the plate). An idea to produce a steel frame from solid steel, cutting, drilling, milling and laser or plasma cutting came about during the discussion of possible solution. This type of production is the first of its kind in the world.

The steel frame is heavier than a cast iron frame; however, its design allows for a much larger open area of the soundboard. The steel frame is far more stable than its cast iron predecessor. Frame stability has a great influence on the quality and stability of tuning and regulation of the piano action.

This grand piano has a very good sound, and very high stability in the action and its tuning of stability.
