Siderstamp was established in 1982 as a limited liability partnership (SAS) among Mr. Giuseppe Testa and his sons Generoso, Roberto and Alessandro.
Since early 1900 the family started to acquire its knowhow in the field of sheet metal works: the family’s grandfather through the manufacturing and handmade transformation of coaches, the father through the manufacturing of cabins for vans and vehicle bodywork implemented using “simple” yet effective tools.

These are the roots of the Company’s know how.

Over time, professional growth and the constant acquisition of always more sophisticated technologies were added to the experience part of a long family tradition.

Quality, environmental protection and pollution prevention along with a social responsibility system are the proofs of the excellent results accomplished, accompanied by value added characteristics that the Company offers to its stakeholders: determination, optimism and organizational efficiency under a light of constant cooperation with the client.

Sheet metal works for the manufacturing of semi-finished metal products and components for the automotive, railway and aerospace industry; manufacturing in medium-light and heavy carpentry with a focus on 2D and 3D laser machining.

The activity is carried out in the municipal district of Montefredane, which is part of the industrial core of the city of Avellino, in a 5,000 square meter covered facility featuring also 3,000 square meters of yard.

The knowhow of a Company is always the result of experience, experience that it processed and acquired from those who worked on it in since the beginning.
Policies, organizational efficiency and flexibility while always looking at the future with determination and optimism make the client’s expectations turn into the perfect product for your needs.
