Generally _____________ are subjected to galvanising (i.e., zinc coating)?
Correct answer: C. Low carbon steels
- A. Non-ferrous metals
- B. Non-metals
- C. Low carbon steels
- D. Stainless steel
Explanation
Low-carbon steel sheets are commonly galvanised because zinc protects the exposed steel both as a barrier and through sacrificial action. Stainless steel already has corrosion resistance, while non-ferrous metals do not require zinc coating for this purpose.
