Choosing the best metal for a facade involves considering project requirements, rerehua, maintenance, environmental impact, and cost. Popular options include aluminum composite material for strength and versatility, stainless steel for corrosion resistance, zinc for durability, and nickel-containing stainless steel for visual appeal. Copper offers a unique patina, while titanium-zinc aluminum composite panels are fire-resistant. Seeking professional advice ensures the right material is chosen for safety and design needs.
