Galvanneal sheets offers good paintability weldability corrosion resistance and formability.
Galvanneal sheet metal gauge.
Galvannealed steel is readily paintable.
In comparison to galvanized steel the coating is.
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.
All other gauges tolerances shown are for width over 32 to 60 inclusive.
Gauges 10 11 12 tolerances shown are for widths over 40 to 60 inclusive.
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.
The steel is then annealed which converts the zinc into a zinc alloy coating that offers increased corrosion and scratch resistance.
However the zinc alloy coating on galvannealed sheet is more brittle than the zinc coating of galvanized sheet.
This is preferred over galvanized if the metal is to be painted.
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.
As a result some amount of powdering can appear when the metal is formed.
These will vary from british gauges with some exceptions.

The gauges shown above are based on american galvanneal sheet steel manufacturers gauge thickness.
Galvanneal steel galvannealed sheet metal available in different gauges.
Galvannealed steel sheet metal also known as galvanneal is the result of galvanizing followed by annealing of sheet steel.
Galvannealed product is an ideal material for painted product applications.
Avoid painted metal degradation with resilient galvannealed steel sheet and coil products from alliance steel.
May have minor scratching.
Galvannealed steel has very similar properties as standard galvanized but the surface has a more porous and abrasive finish that more readily accepts paint.
Has no protective film.
