Galvanized Sheet Metal Vs Aluminum

Cost and price are always an essential factor to consider when making any product.

Galvanized sheet metal vs aluminum.

The aluminum is added to improve the adhesion between the coating and the steel substrate during formation. Galvanized steel is essentially pure zinc with a very small percentage of aluminum. 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. It is ductile corrosion resistant flexible and a good thermal conductor.

When working with sheet metal it is common for the term gauge to be used someone unfamiliar with the gauge system may not understand what is meant by 18 gauge steel for example. Aluminum vs steel cost. This is known as a galvanized metal. If we compare galvanized and aluminium steel for facade construction steel with zinc plating and aluminum alloy sheets are the closest competitors.

Kynar aluminum for metal roofing. But nevertheless steel sheet has advantages. G90 is the best thickness for spinning and the industry standard for coating astm a653. Galvanized steel has better corrosion resistance.

The question is frequently asked when two dissimilar metals are placed in contact with each other. Kynar galvalume steel for metal roofing and gutters. Galvannealed steel is the preferred coated steel for use in architectural applications. However steel is generally cheaper per pound than aluminum see galvanized vs stainless for more info on steel.

The combination of aluminum and zinc is used once again as a protective layer to the steel. Iron or steel can be coated with zinc. Aluminum is also weather resistant and can be machined thinned into wires and sheets or soldered. 24 gauge 20 gauge 18 gauge and 16 gauge.

Aluminum is a metal and it has all the attributes of metal that are. 26 gauge 24 gauge 20 gauge 18 gauge 16 gauge 14 gauge 1 8 and 1 4. 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. What happens when i put galvanized steel together with aluminum parts or put aluminum sheets on galvanized steel studs.

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. Difference between aluminum and galvanized steel is obtained by comparing the properties of both. The price of steel and aluminum is continually fluctuating based on global supply and demand fuel costs and the price and availability of iron and bauxite ore. Aluminum vs galvanized steel.

The chart below shows the electrode potentials of metals in seawater. At the same thickness steel is 2 5 3 0 times stronger.
