Corten steel is a type of steel made from a chemical alloy that protects it from atmospheric corrosion. Thanks to this, and its natural and decorative appearance, it is a very versatile material for architects and designers.


Brass is an alloy of copper and zinc, with a proportion of more than 50% copper. Brass is often used in projects requiring high design and aesthetics.


The titanium finish is achieved by a chemical oxidisation process that provides a high quality design and metallic aesthetics.


The lacquering treatment consists of protecting and painting the surface of the profile with a homogeneous layer of paint. These treatments are carried out with the utmost respect for the environment, which is why all paints are lead-free.


Stainless steel is a material widely used in construction due to its hardness and high resistance to corrosion.
