Galvanneal Sheet Metal Gauge

Has no protective film.

Galvanneal sheet metal gauge.

Galvannealed steel is readily paintable. 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. 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. These will vary from british gauges with some exceptions.

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. In comparison to galvanized steel the coating is. Galvannealed steel sheet metal also known as galvanneal is the result of galvanizing followed by annealing of sheet steel.

Avoid painted metal degradation with resilient galvannealed steel sheet and coil products from alliance steel. Galvannealed product is an ideal material for painted product applications. A gauge conversion chart can be used to determine the actual thickness of sheet metal in inches or millimeters. 60 x 120 galvannealed flat sheet a40 20 gauge item.

However the zinc alloy coating on galvannealed sheet is more brittle than the zinc coating of galvanized sheet. As a result some amount of powdering can appear when the metal is formed. May have minor scratching. Galvannealed steel has a matte grey color uniform which can be easily painted.

The steel is then annealed which converts the zinc into a zinc alloy coating that offers increased corrosion and scratch resistance. For example 18 gauge steel according to a gauge conversion chart is 0 0478 inch or 1 214 millimeter. 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. 18 26 gauge 48 and 60 wide products.

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 steel is carbon steel coated with zinc using a hot dipped process. The gauges shown above are based on american galvanneal sheet steel manufacturers gauge thickness.
