Patina is called the noble pink surface of cortes. It develops over time and under the influence of weather. This process can take different lengths according to weather conditions, since the sheet metal requires a steady change between wet and dry in order to fully design the grate surface. In principle, however, it can be assumed that it is completed after about 6 months.
However, the process can also be artificially accelerated. Either by using appropriate chemicals, using salt water or by regularly moistening the corten steel sheets in dry weather. In any case, you get the characteristic surface.
