Galvanized Sheet Metal Vs Aluminum

At the same thickness steel is 2 5 3 0 times stronger.

Galvanized sheet metal vs aluminum.

The aluminum is added to improve the adhesion between the coating and the steel substrate during formation. Galvanized steel has better corrosion resistance. At wenzel we take pride in making high quality parts and use only g90 galvanized sheet meaning there is 90 ounces of zinc coating per square foot or steel sheet. But nevertheless steel sheet has advantages.

If we compare galvanized and aluminium steel for facade construction steel with zinc plating and aluminum alloy sheets are the closest competitors. Galvannealed steel is the preferred coated steel for use in architectural applications. The combination of aluminum and zinc is used once again as a protective layer to the steel. Aluminum is a metal whereas galvanized steel is obtained by a hot dipping process in which carbon steel is dipped into zinc.

Iron or steel can be coated with zinc. G90 is the best thickness for spinning and the industry standard for coating astm a653. Galvalume is aluminum and zinc coated steel. The zinc acts as a protective layer to iron or steel to prevent rust.

Galvanized steel has a porous and rough surface which is difficult to clean. Specification astm a 653 a 653m coating designation a a60 a40 galvanized steel zinc coated by the hot dip process resulting in a full spangled finish galvanized steel is less conducive to forming welding and painting.
