Production in the PETROF factory and its logistics have passed through many changes compared to earlier methods. Despite the effort of incorporating modern technology, the company insists on making instruments by hand, which guarantees the instruments have high tone quality.
The timeless style of the instruments with a brilliantly clear and rich sound and widen and colourful range of the musical voice is the result of the perfect treatment of each detail.
Unlike a lot of other manufacturers of key instruments, the PETROF plant produces a substantial part of raw products and instrument parts itself. The company workshops produce resonance boards, keyboards, hammers, strings, metal parts and a number of other parts. The only exception being cast iron frameworks and piano bodies, which are purchased.
At the customer"s wish it is possible to also use other parts from specialized world manufacturers . In some cases there is direct cooperation between them and PETROF. An example is the very successful close cooperation with the famous RENNER company. Besides original Renner actions and hammers , PETROF instruments also use the RENNER-PETROF actions.
