Which statement about zinc-coated sheets is true?

• A. They are easy to paint and corrosion resistant, making them good for roofs.
• B. They peel easily and rust quickly.
• C. They cannot be painted.
• D. They are not suitable for roofing.

Answer: (A)

Zinc coating on steel provides durable corrosion resistance and also gives a surface that can be painted when prepared correctly. The zinc acts as a sacrificial layer, protecting the steel underneath from rust, which is why galvanized sheets hold up well in outdoor roofing environments. Because the coating withstands weather and the surface can accept paint with proper cleaning and priming, galvanized sheets are commonly chosen for roofs. The other statements don’t fit because galvanizing does not cause rapid rust or easy peeling, painting is possible, and these sheets are indeed suitable for roofing.
