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.
