Galvanneal Sheet Metal Gauge

18 26 gauge 48 and 60 wide products.

Galvanneal sheet metal gauge.

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 has very similar properties as standard galvanized but the surface has a more porous and abrasive finish that more readily accepts paint. Galvannealed product is an ideal material for painted product applications. 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.

For example 18 gauge steel according to a gauge conversion chart is 0 0478 inch or 1 214 millimeter. However the zinc alloy coating on galvannealed sheet is more brittle than the zinc coating of galvanized sheet. The steel is then annealed which converts the zinc into a zinc alloy coating that offers increased corrosion and scratch resistance. This is preferred over galvanized if the metal is to be painted.

The gauges shown above are based on american galvanneal sheet steel manufacturers gauge thickness. Galvannealed steel is readily paintable. Galvannealed steel is carbon steel coated with zinc using a hot dipped process. Galvannealed steel sheet metal also known as galvanneal is the result of galvanizing followed by annealing of sheet steel.

These will vary from british gauges with some exceptions. 60 x 120 galvannealed flat sheet a40 20 gauge item. In comparison to galvanized steel the coating is. May have minor scratching.

Has no protective film. Galvanneal sheets offers good paintability weldability corrosion resistance and formability. As a result some amount of powdering can appear when the metal is formed. Galvanneal steel galvannealed sheet metal available in different gauges.

Avoid painted metal degradation with resilient galvannealed steel sheet and coil products from alliance steel. The equivalent thicknesses differ for each gauge size standard which were developed based on the weight of the sheet for a given material. 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.
