International standard ISO12944 "Coatings. Protection steel structures from corrosion using coating systems" in its second part classifies environmental conditions into 6 categories based on their corrosive effect. Category C4 corresponds to high. Under such conditions, metal (in particular steel) is subject to a significant risk of rapid corrosion wear, therefore strict anticorrosion protection is required. Typically, this refers to industrial areas with high humidity and pollution, or coastal zones with moderate salinity.
Yes, we can offer several systems to choose from based on service conditions. System for conditions without UV exposure: 1*180 µm ARMEPOX 243 mastic. For conditions with UV exposure, 1*180 µm ARMEPOX 243 + 60 µm ARMOPUR DTM 162. Service life from 7 to 15 years.
Category C4 corresponds to environment class HA2. (Table 37. CH.2.01.07.-2020).
