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.
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 ...
Galvanism is a term invented by the late 18th-century physicist and chemist Alessandro Volta to refer to the generation of electric current by chemical action. [2] The term also came to refer to the discoveries of its namesake, Luigi Galvani , specifically the generation of electric current within biological organisms and the contraction ...
In 1799 Volta invented the voltaic pile, which is a stack of galvanic cells each consisting of a metal disk, an electrolyte layer, and a disk of a different metal. He built it entirely out of non-biological material to challenge Galvani's (and the later experimenter Leopoldo Nobili )'s animal electricity theory in favor of his own metal-metal ...

In 1974 Sendzimir invented a spiral steel looper used in both the United States and Japan. Ninety percent of the world's galvanized steel production went through the Sendzimir process by the early 1980s. Poland, France, the United Kingdom, Japan, and Canada purchased his steel mills and technologies over the years.
Galvanised hand rail Crystalline surface of a hot-dip galvanized handrail, known as "spangle" Protective effect: completely rusted letter box mounted to a hot-dip galvanized wall Steel strip coming out of the zinc pot of a continuous vertical hot-dip galvanizing line. Hot-dip galvanization is a form of galvanization.
Sherardising is a process of galvanization of ferrous metal surfaces, also called vapour galvanising and dry galvanizing.The process is named after British metallurgist Sherard Osborn Cowper-Coles (son of naval inventor Cowper Phipps Coles) who invented and patented the method c. 1900.
