On the other hand, we produce special screws for the DIY sector. In both cases, fasteners made of stainless steel are produced on request. We also offer packaging services as well as Ruspert® and wax coatings and heat treatments. In addition to that we also provide customized screws based on your drawings.

Terrassenbau
The creation of an ETA and its use as the basis for CE marking are clearly defined and regulated processes. Nevertheless, it takes a lot of effort and experience to implement them correctly. Therefore, especially in the field of regulation and approval, we recommend not to take unnecessary risks, but to work with experts who have a lot of experience with the dynamic regulatory environment and the specific technical and logistical requirements of a manufacturer.
At AVVIO, we offer a unique package: for more than 35 years, we have been involved in the manufacture and approval of fasteners for structural timber construction. Internal product testing prior to application, which ensures the necessary performance, completes our service.
