Hot dip galvanized steel (HDG) is steel that has been dipped in molten zinc in order to produce a rust-resistant coating. The term galvanizing usually refers to the hot dip method; it is also sometimes called zinc hot dipping. A characteristic crystalline pattern, called spangling, is often left on the surface of the steel. Hot dip galvanized steel is used in applications where steel may be exposed to weather, but where stainless steel is too expensive.
