AUJOR contributes to stainless steel treatment for the central towers of the Sagrada Família

Our expertise in pickling and passivation of super duplex stainless steel has contributed to one of the world's most iconic architectural projects.

The construction of Barcelona's Sagrada Família demonstrates how architecture, engineering and industrial technology come together to meet highly complex technical challenges.

AUJOR has contributed to the construction process of its six central towers, providing specialist expertise in the treatment of super duplex stainless steel structures.

Our work involved pickling, passivation and corrosion-related verification tests on structures made of stainless steel reinforcing bars and flat bars.

These components form part of the system used to pre-assemble the stone blocks of the towers, where dimensional precision and material reliability are essential.

The treatments remove surface contaminants and alterations, promote the formation of the stainless steel's protective passive layer and contribute to its corrosion resistance.

Being involved in such an internationally recognised project highlights our technical specialisation and demonstrates the importance of surface treatments in demanding industrial and construction applications.

At AUJOR, we continue to provide specialised solutions that enhance the performance and reliability of stainless steel.
