About Metalbox
Thirty-five years building anywhere in the world
Metalbox was born from one conviction: modular construction is not an alternative; it is the smartest way to build. Behind that conviction stands a career: that of Jesús Rabadán, founder and project director, with more than 35 years leading modular and industrial construction across three continents.
Company“My commitment is to bring experience, rigour and leadership to turn every project into a solid, sustainable result.”
