The NACE 01210-2010 standard addresses the issue of preventing corrosion in steel frames within masonry buildings. The standard acknowledges two methods of treatment, namely treating the steel and changing the environment or controlling the corrosion process electrochemically through cathodic protection (CP).

The standard notes that the traditional method of treatment involves removing the facade, applying protective coatings to the steel, and preventing moisture ingress. However, this approach is often impractical and expensive, especially when dealing with large sections of masonry or heritage buildings. Therefore, the use of cathodic protection becomes a viable alternative. CP involves passing a protective current through the stonework or masonry to the steel through the mortar/masonry contact.

The standard stresses the benefits of CP, which include cost savings, minimal disruption to building occupants, and the conservation advantages, particularly valuable for heritage buildings. However, it acknowledges that determining the connection between the steel and masonry elements can pose challenges. This standard provides guidance on implementing cathodic protection to ensure the effective corrosion prevention of steel frames in masonry buildings, offering a solution that is practical, cost-effective, and conducive to preservation efforts.
