Galvanneal sheet metal gauge.

Galvannealed steel is carbon steel coated with zinc using a hot dipped process. Galvannealed steel is readily paintable. Galvannealed steel sheet metal also known as galvanneal is the result of galvanizing followed by annealing of sheet steel. Galvannealed sheet can be formed much in the same way and by the same variety of processes as galvanized sheet.

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. Galvanneal sheets offers good paintability weldability corrosion resistance and formability. These will vary from british gauges with some exceptions. As a result some amount of powdering can appear when the metal is formed.

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. Avoid painted metal degradation with resilient galvannealed steel sheet and coil products from alliance steel.

Gauges 10 11 12 tolerances shown are for widths over 40 to 60 inclusive. 60 x 120 galvannealed flat sheet a40 20 gauge item. In comparison to galvanized steel the coating is. Galvanneal steel galvannealed sheet metal available in different gauges.

Galvannealed product is an ideal material for painted product applications. 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. Has no protective film. This is preferred over galvanized if the metal is to be painted.

May have minor scratching. The gauges shown above are based on american galvanneal sheet steel manufacturers gauge thickness. However the zinc alloy coating on galvannealed sheet is more brittle than the zinc coating of galvanized sheet.
