Galvanized sheet metal vs aluminum.

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

Galvanized steel has better corrosion resistance. This is known as a galvanized metal. Galvanized steel is essentially pure zinc with a very small percentage of aluminum. The aluminum is added to improve the adhesion between the coating and the steel substrate during formation.

Iron or steel can be coated with zinc. Galvanized steel has a porous and rough surface which is difficult to clean. 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.

This is achieved through a multi step process where a steel sheet is immersed in pure molten zinc at a very high temperature bonding the zinc to the steel. But nevertheless steel sheet has advantages.
