What is a major concern when using electro-galvanized fasteners in tile installations?

The primary concern with using electro-galvanized fasteners in tile installations is corrosion over time. Electro-galvanized fasteners receive a thin zinc coating that provides some level of protection against rust, but this coating is less durable than other forms of galvanization, such as hot-dip galvanizing. In environments where moisture is present, particularly in wet areas like bathrooms or kitchens, the electro-galvanized layer can wear away, exposing the bare metal underneath. This exposure increases the risk of corrosion, which can compromise the integrity of the fasteners and the overall tile installation.

When fasteners corrode, it can lead to problems such as loosening tiles, cracks in the substrate, and potential water damage if the installation fails. The longevity and performance of the installation can be significantly affected, making it essential for inspectors to recognize this vulnerability when evaluating tile installations that use electro-galvanized fasteners.

Other options do not address the specific issues related to the use of electro-galvanized fasteners in tile installations. Concerns about structural integrity typically relate to the overall design and strength of the installation rather than the fasteners themselves. Insulation properties and heat resistance are not fundamental concerns associated with fasteners in tile installations, as
