The galvanising bath contains slightly over 0.1% aluminium, added to form a layer bonding between the iron and coated zinc. [2] [3] Annealing temperatures are around 500 to 565 °C. [2] Pre-1990 annealing lines used gas-fired heating; post-1990s the use of induction furnaces became common. [1]
Galvanized surface with visible spangle. Galvanization (also spelled galvanisation) [1] is the process of applying a protective zinc coating to steel or iron, to prevent rusting. The most common method is hot-dip galvanizing, in which the parts are coated by submerging them in a bath of hot, molten zinc. [citation needed]
Galvanized fumes are released when the galvanized metal reaches a certain temperature. This temperature varies by the galvanization process used. In long-term, continuous exposure, the recommended maximum temperature for hot-dip galvanized steel is 200 °C (392 °F), according to the American Galvanizers Association.
However, only "pure" zinc coated steel is typically referred to as PPGI. For example, PPGL may be used for pre-painted 55%Al/Zn alloy-coated steel (pre-painted GALVALUME(r) steel*) Over 30 million tons of such coated steel is produced today in over 300 coating lines just in Boxing which is a little county in North of China.

Corrugated galvanised iron (CGI) or steel, colloquially corrugated iron (near universal), wriggly tin (taken from UK military slang), pailing (in Caribbean English), corrugated sheet metal (in North America), zinc (in Cyprus and Nigeria) or custom orb / corro sheet (Australia), is a building material composed of sheets of hot-dip galvanised ...

The term "galvanized" has also been applied to former Union soldiers enlisting in the Confederate Army, [1] including the use of "galvanized Yankees" to designate them. [2] At least 1,600 former Union prisoners of war enlisted in Confederate service in late 1864 and early 1865, most of them recent German or Irish immigrants who had been drafted ...
