Final answer:
Aluminum is used in construction for skylights, sloped glazing framing, and roofs and walls of sunrooms due to its strength, lightness, and resistance to corrosion.
Step-by-step explanation:
The uses of aluminum structural members or aluminum panels vary widely in the construction industry due to the material's unique properties such as lightness, toughness, strength, and resistance to corrosion. Aluminum's applications in construction include skylights and sloped glazing framing, which take advantage of its lightweight and durable nature, making it ideal for supporting glass structures without adding excessive weight. Additionally, aluminum is often used for the roofs of sunrooms and the walls of sunrooms where its corrosion resistance and strength are crucial for supporting glazing and withstanding environmental elements. Therefore, the correct answer to the question regarding the uses of aluminum in the described scenarios is 4) All of the above.
