Another popular choice is galvanized steel sheet metal. Steel offers high tensile strength, making it an ideal option for RV roofs that require a robust structure to withstand weathering and potential impacts. Galvanization provides a protective coating that helps prevent rust formation and corrosion, thereby enhancing the lifespan of the roof. While steel is heavier than aluminum, its strength-to-weight ratio can be advantageous in specific designs where structural integrity is paramount.

While E110 is approved for use in many countries, there have been ongoing debates about its safety. Some studies suggest that artificial colorings, including E110, may be linked to adverse effects, particularly in children. Concerns have been raised about hyperactivity and attention issues associated with certain food dyes. As a result, some countries, such as those in the European Union, require products containing E110 to include warning labels indicating that the additive may have an adverse effect on activity and attention in children.
