Materials monitoring

ICP Materials carries out activities that aim to describe and evaluate long-term corrosion and soiling trends attributable to atmospheric corrosion.

These trends are monitored through “trend exposures” that evaluate the corrosion and soiling of selected materials during one, four and eight-year cycles, including samples of carbon steel, weathering steel, stainless steel, zinc, copper, aluminum, coil coated materials, limestone, and analysis of soiling of glass, limestone and marble.
