When selecting materials, prioritize Aluminum Alloy for a sleek, lightweight, and rust-resistant finish, which is ideal for high-humidity areas like bathrooms. For a more premium feel, Stainless Steel (304 grade) offers superior corrosion resistance and a high-end polished look. If the target market prefers eco-friendly options, PS (Polystyrene) is a cost-effective, moisture-proof alternative that can mimic wood textures without the risk of warping. Ensure the backing material is MDF or moisture-resistant plywood to provide structural integrity and prevent the glass from flexing.
