Galvanneal Sheet Metal Gauge

Galvanneal sheets offers good paintability weldability corrosion resistance and formability.

Galvanneal sheet metal gauge.

Galvanneal steel galvannealed sheet metal available in different gauges. Galvannealed sheet can be formed much in the same way and by the same variety of processes as galvanized sheet. Gauges 10 11 12 tolerances shown are for widths over 40 to 60 inclusive. May have minor scratching.

The gauges shown above are based on american galvanneal sheet steel manufacturers gauge thickness. This is preferred over galvanized if the metal is to be painted. Galvannealed steel has very similar properties as standard galvanized but the surface has a more porous and abrasive finish that more readily accepts paint. Galvannealed steel is readily paintable.

The steel is then annealed which converts the zinc into a zinc alloy coating that offers increased corrosion and scratch resistance. Galvannealed steel is carbon steel coated with zinc using a hot dipped process. Galvannealed steel has a matte grey color uniform which can be easily painted. In comparison to galvanized steel the coating is.

18 26 gauge 48 and 60 wide products galvannealed sheet and coil are made with a cold rolled substrate or base metal that is hot dipped with zinc and then subjected to an annealing process that forms a zinc iron composite on the surface. As a result some amount of powdering can appear when the metal is formed. Avoid painted metal degradation with resilient galvannealed steel sheet and coil products from alliance steel. Has no protective film.

Galvannealed product is an ideal material for painted product applications. Galvannealed steel sheet metal also known as galvanneal is the result of galvanizing followed by annealing of sheet steel. As a registered iso 9001 2015 company rolled steel products state of the art equipment meets virtually any requirement in panel flat quality leveling precision slitting close tolerance sheet blanking strip quality edge conditioning precision shearing and complete cold reducing capabilities. Sheet metal gauge size chart gauge or gage sizes are numbers that indicate the thickness of a piece of sheet metal with a higher number referring to a thinner sheet.

60 x 120 galvannealed flat sheet a40 20 gauge item. All other gauges tolerances shown are for width over 32 to 60 inclusive. However the zinc alloy coating on galvannealed sheet is more brittle than the zinc coating of galvanized sheet.
