Hot-dip galvanization - Wikipedia

The process of hot-dip galvanizing results in a metallurgical bond between zinc and steel, with a series of distinct iron-zinc alloys. The resulting coated steel can be used in much the same way as uncoated. A typical hot-dip galvanizing line operates as follows Steel is cleaned using a caustic solution. This removes oil/grease, dirt, and paint.
