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.

1. Wire Diameter The wire diameter is a critical measurement that indicates the thickness of the individual wires used in the mesh. Common wire diameters range from 1.6 mm to 6 mm (approximately 14 to 4 gauge). A thicker wire typically provides more strength, making it ideal for heavy-duty applications.
