Why is joint reinforcement often galvanized in masonry construction?

Joint reinforcement is often galvanized in masonry construction primarily to reduce the effects of corrosion. Galvanization involves applying a protective zinc coating to steel materials, which acts as a sacrificial barrier against moisture and other environmental factors that can lead to rust and deterioration. In masonry, where joint reinforcement is frequently exposed to moisture from rain, snow, or humidity, galvanization is essential to prolong the lifespan of the reinforcement and maintain the structural integrity of the masonry.

Although improving appearance, increasing tensile strength, and enhancing adhesion are important factors in masonry construction, they are not the primary reasons for galvanizing joint reinforcement. The main goal of galvanization is to ensure that the materials used in construction can withstand environmental conditions over time without succumbing to corrosion, which could compromise the overall stability and strength of the masonry system.
