Age old expertise and modern construction methods aid in determining the finest materials needed to build Haessler instruments, thus assuring that the wood that is best suited is chosen for each part. The parts are then assembled with great care to assure high performance and continuous high quality that makes the Haessler outstanding in its class.

The soundboard is made from the finest spruce harvested from the eastern Alps of Austria. Careful attention is given to the grain direction and the grain tightness to ensure expressive tonal response.

The soundboard crown is precisely formed to provide rich resonance. Selected hardwoods laminated together to form the bridge provide the vital link between the soundboard and strings that produces Haessler's colourful tone.

The pin block is made of 18 or more layers of compressed durable beech hardwood, wihch forms a firm foundation for the tuning pins.

The strings are made of special high elastic steel, precision drawn for evenness in size. Copper wound bass strings are made in house to ensure high quality and careful attention to our scale design.

The iron frame must take the high tensions of the strings which easily approaches 20 tons. However, it also is an important decorative part of the instrument. The arts of designing and engineering have created a form that is appealing to the eye.

The casting is done in grey iron which is afterwards polished to its glimmering appearance.

The action of the Haessler grand is made using traditional materials proven for trouble free use, completely devoid of plastic (artificial) materials.

The keys are made of spruce, weighted individually to produce a responsive touch throughout the scale.

The hammers are fabricated of carefully selected and processed felt that matches the requirements for different densities from the lower to the upper notes.

This carefully made and assembled action gives the pianist every advantage to meet even demanding musical needs.

The Rim: Solid spruce bracings reinforce a multi laminated rim. The Cross Beams are made of solid red beech for extra stability. The Outer Rim features a multi layer construction while the inside is decorated with select bird's eye maple.

The top lid is fitted with chamfered edging with a 2-stage lid prop.

The legs are solid wood, with a dovetail system for easy fastening, and fitted with fine brass casters.

The pedals include unacorda, sostenuto, and sustain (3 pedal system).
