Galvanized Steel Sheet Properties

The properties of galvanized steel are a unique combination that make it ideal for use in interior and exterior applications such as car bodies appliances nuts and bolts roofs and rebar.

Galvanized steel sheet properties.

Some drinking water pipes are still made from galvanized steel. It is the hardness value obtained by applying 980n pressure to the steel ball with a diameter of 1 59mm. Nuts bolts tools and wires of all kinds are now galvanized because it is a cheap process and helps boost the metal s lifespan. 1 t bends in many of the steels were embrittled by galvanizing but galvanized 2 t and 3 t bends in all steels could be completely straightened.

This is the most common use for galvanized metal and hundreds of thousands of tons of steel products are galvanized annually worldwide. According to the american galvanizers association galvanized steel resists corrosion up to 100 times better than uncoated steel. When exposed to the atmosphere the pure zinc zn reacts with oxygen o 2 to form zinc oxide which further reacts with carbon dioxide co 2. In developed countries most larger cities have several galvanizing factories and many items of steel manufacture are galvanized for protection.

In the last 2 3 decades a large body of literature has been published on further enhancements of the corrosion properties of hdg by additions of magnesium aluminium or a combination of both. The steel features good resistance to chemicals red rust acid and base when applied to surfaces and points of machining. Galvanized steel in particular is often what is used in modern steel frame buildings. 61 67 new coating alloys containing aluminium and magnesium have been developed for continuous galvanized steel sheet.

Cool rolled sheet metal is also frequently galvanized. Thus the tensile strength proof strength and tensile elongation of cold rolled steel were unaffected except that the tensile elongation of 40 cold rolled steel tended to be increased by galvanizing. 61 69 the zinc magnesium. It is suitable for measuring soft metals such as nonferrous metals annealing and normalizing steel.
