Structural steel is generally used for important purposes such as load-bearing, and is often used in steel structure projects, with good corrosion resistance and processing performance
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.
✔The caustic cleaning solution is rinsed off.
✔The steel is pickled in an acidic solution to remove mill scale.
✔The pickling solution is rinsed off.
✔A flux, often zinc ammonium chloride is applied to the steel to inhibit oxidation of the cleaned surface upon exposure to air. The flux is allowed to dry on the steel and aids in the process of the liquid zinc wetting and adhering to the steel.
✔The steel is dipped into the molten zinc bath and held there until the temperature of the steel equilibrates with that of the bath.
