The zinc protects the base metal by acting as a barrier to corrosive elements and the sacrificial nature of the coating results in a long lasting and high quality steel product.
Galvanised steel sheet properties.
Galvanized steel is among the most popular steel types because of its extended durability having the strength and formability of steel plus the corrosion protection of the zinc iron coating.

Alloyed coating a 25.
While molten zinc solidifies on the surface of the steel sheet normal zinc crystallization is suppressed creating fine crystals.
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 without cracking.
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.
Its good plating reliability rust inhibition and cost effectiveness make it ideal for many industries.
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.
Properties of galvanized steel.
Typical of astm steel.
