There are many products which protect structural steel from corrosion. There is also an intense focus on sustainability. Hot-dip galvanizing is one product that provides economical, long-lived, and sustainable corrosion protection. It is also more durable than most other barrier systems. Not all steel can be galvanized because sometimes the elements are too long and/or too heavy to be placed in the baths. Also, at times the intended environment is not conducive for zinc longevity such as acidic environments or immersed in salt water. But for those applications where galvanizing is appropriate, why would anyone not choose to hot-dip galvanize steel?
