Soft steel coated with zinc is called what?

• A. Galvanized steel
• B. Stainless steel
• C. Tin plated steel
• D. Steel with chrome plating

Answer: (A)

Zinc coating on steel provides corrosion protection by sacrificially protecting the iron and by forming a protective barrier. When soft steel is coated with zinc through a process like hot-dip galvanizing, the result is galvanized steel. This coating prevents rust and extends the life of the steel in moisture-rich environments. Stainless steel, on the other hand, is steel alloyed with chromium (and sometimes nickel) to resist corrosion without zinc. Tin plating coats steel with tin for corrosion resistance in certain applications, but it’s tin here, not zinc. Chrome plating adds a chromium layer for hardness and a bright finish, not zinc protection. So the zinc-coated option is the galvanized steel.
