The Siena can be used all year round, as the thick frame posts are made of heavy gauge aluminum. The entire structure, including the roof panels and all screws, nuts, and bolts, is completely rust-proof. The frame is powder-coated a sharp mocha brown color to further protect it against the elements.

The architectural-grade hard top roof is made of aluminum composite panels that provide strength, noise reduction, and insulation. It has a built-in roof vent to accommodate windy days, and the roof panels carry a five year limited warranty against defects, though they are expected to last much longer.
