The cast iron plate of an upright piano is subjected to as much as 20 tons of string tension. To enable our plates to withstand this tremendous stress, we use state-of-the art CAD technology to match the strength and natural tonal resonances of the plate to the requirements of the scale design. The proper combination of plate design, back post structure, and string tension provides an extraordinary foundation for outstanding tone and durability.
