Zam is a remarkably superior corrosion resistant hot dip zinc aluminum magnesium alloy coated steel sheet product.
Hot dip zinc coated steel sheet.
Density g cc typical of astm steel.
Astm a standard specification for general requirements for steel sheet zinc coated galvanized by the hot dip.
1 2 the product is produced in various zinc or zinc iron alloy coating weights masses or coating designations as shown in table 1 and in table s2 1.
It is the process of coating iron and steel with zinc which alloys with the surface of the base metal when immersing the metal in a bath of molten zinc at a temperature of around 449 c 840 f.
Hot dip galvanization is a form of galvanization.
With its tight metallurgical bond between the steel and the coating zincgrip steel provides the strength and formability of steel plus the corrosion protection of zinc.
1 1 this specification covers steel sheet zinc coated galvanized or zinc iron alloy coated galvannealed by the hot dip process in coils and cut lengths.
Zinc protects the base metal by providing a barrier to corrosive elements and preferentially corroding in place of the base steel.
Protection against rust with zinc coating zinc coating z produced on both sides by hot dip galvanizing extends the service life of the end product by protecting the steel from corrosion.
When exposed to the atmosphere the pure zinc zn reacts with oxygen o 2 to form zinc oxide zno which further reacts with carbon dioxide co 2 to form zinc carbonate znco 3 a usually dull grey fairly strong material that protects.

The continuous hot dip galvanizing process offers a wide protection range from z100 to z600 in addition to a tight bond between the coating and the steel.
