Galvanneal Sheet Metal Gauge

This is preferred over galvanized if the metal is to be painted.

Galvanneal sheet metal gauge. Thickness inches thickness inches galvanized galvannealed aluminized sheet. Galvannealed sheet can be formed much in the same way and by the same variety of processes as galvanized sheet. Galvannealed steel has a matte grey color uniform which can be easily painted. 60 x 120 galvannealed flat sheet a40 20 gauge item.

The equivalent thicknesses differ for each gauge size standard which were developed based on the weight of the sheet for a given material. Galvannealed steel has very similar properties as standard galvanized but the surface has a more porous and abrasive finish that more readily accepts paint. The steel is then annealed which converts the zinc into a zinc alloy coating that offers increased corrosion and scratch resistance. Galvanneal steel galvannealed sheet metal available in different gauges.

Galvannealed steel is carbon steel coated with zinc using a hot dipped process. 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.

Gauges 10 11 12 tolerances shown are for widths over 40 to 60 inclusive. Avoid painted metal degradation with resilient galvannealed steel sheet and coil products from alliance steel. Galvanneal sheets offers good paintability weldability corrosion resistance and formability. These will vary from british gauges with some exceptions.

Galvannealed steel sheet metal also known as galvanneal is the result of galvanizing followed by annealing of sheet steel. Galvannealed steel is readily paintable. Galvannealed product is an ideal material for painted product applications. Has no protective film.

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