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.

It is suitable for measuring soft metals such as nonferrous metals annealing and normalizing steel. Nuts bolts tools and wires of all kinds are now galvanized because it is a cheap process and helps boost the metal s lifespan. 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. Some drinking water pipes are still made from galvanized steel.

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. 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. Hrc the hardness was obtained by applying 588n pressure at the diamond cone with 120 vertex angle for testing samples.

The steel features good resistance to chemicals red rust acid and base when applied to surfaces and points of machining. Cool rolled sheet metal is also frequently galvanized. This is the most common use for galvanized metal and hundreds of thousands of tons of steel products are galvanized annually worldwide. 61 69 the zinc magnesium.

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. Posmac is a corrosion resistant product that has five to ten times stronger resistance than that of a normal hot dip galvanized steel sheet gi gi h with the same coating weight. 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.
