Timber, the perfect support.


Timber, steel and resin: these are the main components of GSA®-Technology. Glued threaded rods facilitate the high-performance joining of softwood and hardwood components. GSA®-Technology guarantees all three criteria essential for solid structural engineering – rigidity, load resistance and ductile properties.

For engineers, this means that swift scaling of the efficiency ratio is possible. Rigidity calculations can be made based on the gross timber values, which produces a sufficient approximation in most practical construction cases.

Neue Holzbau AG is specialised in timber engineering. By developing the GSA® technology, we have gained a leading position in the field of connection technology. We act as both a partner and a link between timber construction, architects and engineers as well as the client.

You choose whether you want consulting, engineering or the complete package up to project implementation. Our main expertise is in the design of high-performance connectors. We research new technologies, gluing techniques and the use of different types of timber.

You benefit from:

  • Pre-fabrication.
  • Supply of ready-to-use components.
  • Engineering expertise (experience with different timber strength classes and a high level of glulam skill in the case of hardwood and modified timbers).
  • Swiss precision, reliability and quality.
  • Service and engineering support to the highest standards.
