The Difference Between Hot Dip Galvanizing And Pre-galvanizing:

Zinc metal has been used for corrosion protection of steel handrail tubing for more than 100 years. Hot-dip galvanizing is the most widely used method of applying zinc to steel handrail tubing. In this process, the entire handrail tubing is dipped into a bath of molten zinc. A thin layer of zinc alloys with steel forms a metallurgical bond, providing long-term corrosion protection. The benefits of hot-dip galvanizing include low initial costs, long-term corrosion protection, and low maintenance costs. The major disadvantage of hot-dip galvanizing is that it can be difficult to achieve a consistent coating thickness on complex shapes. In addition, the process can be slow and expensive.
