In order to initiate corten steel maturation process, Metalco uses an oxidation process trough weathering. This type of system lends to corten a specific non-uniform aspect and different shades of color are particularly visible in welding areas depending on the fact that in such areas patina process is slower. Shades of colors, indeed, are not a defect.
Corten steel, thanks to the process of maturation/oxidation that characterizes it, is considered a “live” material, which may vary over time, in shades and hues, depending on the shape of the object, the position in which it is installed and according to the cycles of weathering which the object undergoes.
Warning: the average period of “stabilization” of corten maturation process, giving to the material a “testa di moro” (“brown”)
color typical of the oxidized corten, is approximately 12/18 months with adequate weathering.
