Why the other options are wrong
- A. Aluminum is lightweight and corrosion-resistant, but generally not considered as premium in terms of longevity or aesthetic gravitas as copper.
- B. Galvalume steel offers excellent corrosion resistance and longevity but does not match the aesthetic appeal or the ultimate lifespan of copper.
- D. Galvanized steel is durable but lacks the extreme longevity and corrosion resistance of copper, and its aesthetic is more industrial.
