MG-ZN-AL Steel Plate
“MAC” is the abbreviation of “Magnesium Alloy Coated”; they are products covered by ternary alloys made out of Zn-3%, Mg-2.5%, and Al. However, even though they contain the same coating mass as a conventional galvanized product, they have 5 times more resistance to corrosion.
Weight Table for MAC Steel
The anti-corrosion characteristics of “MAC” products are especially visible on cut edges, making them the perfect replacement for heat immersion galvanized products. Customers who have previously purchased GI products can easily switch to “MAC” products, because there are no changes in technical requirements related to processing, assembly or painting.
It is used as a raw material in HVAC, Construction, Automotive, Metalworking, Photovoltaic Industries.
Botanical structures, solar panels, “c” poles for construction, engine parts and parts for air conditioning, are some examples of the products that are manufactured with this material.
Benefits and Differences Against Steel Sheets
The magnesium within the “MAC” coating induces the formation of an extremely stabilized anti-corrosion product called Simonkolleite [Zn5 (OH) 8Cl2 • H2O]. Simonkolleite takes shape on the coating and the base metal in a way very similar to that of a thin adhesive film, protecting your product from the threats of corrosion.
When the “MAC” coating is cut, the coated layer on the top surface will partially dissolve to cover the exposed surface and induce the growth of Simonkolleite.
During the duration of this process, the base metal on the exposed surface is bound to be weak to some degree of oxidation, in which case the red rust may become visible. However, once the film layer has condensed on the exposed surface, it will prevent further corrosion.
