The materials used for the support poles of electric vehicle sunshades are typically selected with a primary focus on lightweight design and cost-effectiveness; common choices include aluminum alloy, galvanized steel tubing, and stainless steel. Aluminum alloy is a widely utilized material due to its light weight and superior corrosion resistance, making it well-suited for daily short-distance travel as it places minimal strain on the vehicle.
Galvanized steel tubing is frequently found in lower-cost or heavy-duty sunshade models. While it offers high structural strength and is relatively inexpensive, it is heavier than aluminum alloy, and its weight can have a more pronounced impact on the electric vehicle's stability during prolonged use. Nevertheless, the galvanization process enhances its rust resistance, enabling it to withstand outdoor environmental conditions.
Stainless steel falls between these two options, offering a balanced combination of structural strength and corrosion resistance, as well as a longer service life. Additionally, certain connectors or mounting components often incorporate engineering plastics or rubber materials to provide cushioning and anti-slip properties, thereby enhancing the overall stability and safety of the installation.
