9 work steps Passion down to the smallest detail

ADGA leaves nothing to chance when selecting and processing the beech wood for its high-quality rulers. From the selection of the most suitable logs to careful storage and drying to finishing, we pay attention to the utmost care, precision - and patience, as it should be for any near-natural product.



The copper beech is one of the most common trees in Germany's forests. Because it loosens and improves the soil with its roots and leaves, it is also called the "mother of the forest". For near-natural forestry, it is therefore a particularly important tree species that is often mixed with other species.



When selecting the logs, we work intensively with the Baden-Württemberg forestry as well as municipalities and private owners. The logs are selected personally with the responsible forester. This ensures that only the ideal, high-quality wood is processed for us.


Raw material wood

The selected logs are transported directly to us by long timber trucks. Short distances are important to us in order to act ecologically. Red beech and hornbeam logs are processed. To guarantee a smooth process, the logs are temporarily stored at our wood yard.


Sawing process

In this step, the debarked logs are sawn for the further production steps, setting the course for a top-quality product to emerge. Correct sawing is an essential prerequisite for expert further processing.


Storage & Drying

Storage and drying are elementary steps in the creation of a ruler. This is the only way we can guarantee constant wood conditions for ADGA rulers. The natural drying process takes many months.


Bring to size

Our natural product wood is made to measure down to the last detail in our own joinery. This is where the machines developed by our own machine builders come into play. This enables us to meet the great challenge posed by wood in a professional and proper manner.



To protect the wood in all places, all rulers are given several coats of dip varnish. All milled and drilled holes on the wood are covered with paint and varnish all around.



With special machines which are developed in-house, the many individual parts of a scale are assembled into a perfect measuring system. The variety from the printed single scale to the colours and the design of the scaling makes our scales so unique.


Final product

The finished ruler is just waiting to receive one of the numerous imprints. It takes between 80 and 150 years from the creation of the basic product wood to a top scale.
