Galvanneal Sheet Metal Gauge

This is preferred over galvanized if the metal is to be painted. The equivalent thicknesses differ for each gauge size standard which were developed based on the weight of the sheet for a given material. 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.

Galvanneal sheet metal gauge.

Galvannealed steel has a matte grey color uniform which can be easily painted. Has no protective film. For example 18 gauge steel according to a gauge conversion chart is 0 0478 inch or 1 214 millimeter. May have minor scratching.

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. These will vary from british gauges with some exceptions. Galvannealed steel has very similar properties as standard galvanized but the surface has a more porous and abrasive finish that more readily accepts paint. However the zinc alloy coating on galvannealed sheet is more brittle than the zinc coating of galvanized sheet.

The gauges shown above are based on american galvanneal sheet steel manufacturers gauge thickness. 18 26 gauge 48 and 60 wide products. 60 x 120 galvannealed flat sheet a40 20 gauge item. 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.

Galvanneal steel galvannealed sheet metal available in different gauges. 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. Galvannealed steel sheet metal also known as galvanneal is the result of galvanizing followed by annealing of sheet steel. A gauge conversion chart can be used to determine the actual thickness of sheet metal in inches or millimeters.

As a result some amount of powdering can appear when the metal is formed. Galvannealed product is an ideal material for painted product applications. Galvannealed sheet can be formed much in the same way and by the same variety of processes as galvanized sheet. Galvanneal sheets offers good paintability weldability corrosion resistance and formability.

Galvannealed steel is carbon steel coated with zinc using a hot dipped process. In comparison to galvanized steel the coating is. Galvannealed steel is readily paintable.
