Outer rim is from alder-tree, laminated by birch plywood.
Inner face is veneered horizontally by Ebony Makassar.
Total thickness 7 cm.
The rim is produced with highest exactness at "CNC machine".

The solid construction of the rim of the P 194 Storm grand piano ensures high and longterm tuning stability and action regulation as well as sound board crown stability which is a prerequisite for perfect performance. Rare Ebony on inner face supports noble appearance of piano.

Frame posts

The connection is provided by fish-tail and beech dowels.
The frame posts are produced with high exactness at "CNC machine".

Solid beech core, solid alder outer lining, gabon counter veneer, outer decorative thin veneer.
The legs are 625 mm long.

The robust construction of the legs ensures high stability of the instrument whilst being played dynamically.

Iron plate

Czech producer. Gray cast iron, wet sand casted, hand finished surface, CNC worked.
New colour.

Precise drilling means exact length of strings and creates good conditions for their optimal oscillation and creation of an exact tone. The iron plate, which is of a vivid light gold tint, perfects the modern design of the instrument. It is possible to harmonize the piano design with the design of its surroundings and to produce a piano with silver metal parts.

Hardware fittings

Petrof original.
Solid brass, polished, lacquered.

Hardware fittings are corrosion resistant, therefore they do not require any maintanance.


Special beech plywood type Multiplex.
Original veneer thickness 2 mm compressed to the density 800 - 850kg/m3 (= 6 veneer layers/cm), high moisture resistant glue.

The pinblock in this grand piano has a high resistance against atmospheric changes (e.g. humidity). It provides equal torque of tuning pins, which results in a particularly high stability of tuning.


Petrof original.
The soundboard is made from European mountain spruce.
It is symmetric crowned, wedge tapered from 9 mm in the front to 7.7 mm in bass arc.

Symmetric crown and wedge tapering of soundboard gives Storm piano round singing tone colour typical for PETROF pianos. Piano is suitable for chamber-music and for advanced players.


Petrof original.
The ribs are made from European spruce and are symmetrically circular shaped.
The cross rib is produced from beech, is straight and is machined at "CNC machine".

Hornbeam and Ebony caps of treble bridge support bright tones of middle and treble frequencies. Foot bridge construction enables excellent sounding of low tones.


Agraffes, front and rear pretuned duplexes.
Laser positioning of duplex bridges (frets).
