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.

4. Market Demand The demand for galvanized iron sheets varies across different sectors, such as construction, automotive, and appliances. Economic growth can lead to increased construction activity and higher demand for roofing materials, consequently driving prices up. Conversely, during economic downturns, demand may decline, leading to price reductions as factories seek to maintain sales.
