The article addresses the reduction of risks associated with the potential emergence
of industrial hazards caused by decreased reliability of corrosion protection systems for structures, within the framework of robust structural design (RDCPS – Corrosion Protection System under Robust Structural Design Conditions). The proposed approach is based on the development of robust (resilient to disturbing external influences) methods for designing primary and secondary corrosion protection measures for metal structures. In order to improve structural operation at all stages of the life cycle, a diagnostic and maintenance technology is substantiated. Enhanced survivability and resistance to aggressive operational environments are achieved through effective robust design
strategies for both primary and secondary protection of metal structures against corrosion. The proposed methodology contributes to the advancement of current standards (EN 1990) by incorporating principles of robust design. It is established that these requirements aim to ensure the quality of metal structures and are implemented through limit state calculations using partial safety factors (EN 1991). Structural load-bearing capacity and durability are ensured in accordance with the provisions of EN 1993. Characteristic values of metal structure quality indicators, protective coatings (EN ISO 12944, EN 1461), and materials (EN 1993-1-4) are applied. The methodology proposed herein is aimed at minimizing risks during the creation of metal structures and reducing the extent of
damage due to corrosion loss, which remains a highly relevant objective in the construction industry.
