It was created by metallurgist sherard osborn cooper coles and patented around 1900.
													
																	Galvanised iron sheets have a coating of which metal. 
									
																	Galvanized coating is the application of zinc coating to prevent corrosion or rusting from the steel or iron structure. 
																	The resulting finish is a dull matte surface. 
																	What is galvanised iron. 
																	Cabinets signs light fixtures or anywhere else that an excellent finish is required are a good fit for electro galvanized bonderized sheets. 
															
													
									
																	The metallic parts that are to be galvanized are put inside of a closed rotating drum along with zinc powder and sometimes a filler like sand. 
																	The liquid zinc adheres to the metal and when you remove the metal out of the bath the zinc will harden. 
																	The application of zinc on a steel structure is a process called galvanization. 
																	This process was first invented and developed in france and england in 1837 in which a sheet of iron or steel was dipped in a molten zinc bath and cooled a method called hot dip galvanization. 
															
													
									
																	Electro galvanized bonderized sheets can be formed rolled or stamped without flaking powdering peeling or cracking. 
																	Galvannealed steel is a zinc iron alloy product where the base metal is coated by the hot dip process then heated to induce alloying between the molten zinc coating and the steel. 
																	A special form of galvanizing called sherardizing is used to create a zinc coating on iron or copper products. 
																	Is steel covered in a zinc coating to protect the steel from corrosion. 
															
													
									
																	The galvanising process involves cleaning the steel and dipping it in a bath of molten zinc solution at temperatures around 450 degrees.
