Integral service

Calderería CPK was founded in 2000 with the name of Calderería Pako, S.L. in Aizarnabal. After years of constant growth, in 2018 the company moved its facilities to Zestoa, deciding that the time had come to change its business name to Calderería CPK.

We have diversified with time, acquiring a great deal of experience in different industrial sectors including the chemistry, food, paper, metallurgy, naval and renewable energies industries, recycling and the environment.

Our commitment to innovation and to remaining at the forefront of technology also enables us to work in highly demanding sectors, producing work for science for example. We have all of the means and facilities required to build large-sized pieces, such as vacuum chambers, tanks and structures, in any quality of stainless steel.
