Galvanneal Sheet Metal Thickness

Galvannealed steel has very similar properties as standard galvanized but the surface has a more porous and abrasive finish that more readily accepts paint.

Galvanneal sheet metal thickness.

We stock a variety of galvanized and galvannealed sheet metal ranging in thickness from 0 027 to 0 138. Coating thickness coating thickness is measured as the coating weight in ounces per square foot. 73 slit width tolerance. Aisi thickness tolerance ranges lbs sq.

0 040 1 01 mm. Galvanneal does not flake off its coating when formed and bent. Galvannealed steel grade data sheet galvannealed steel hot dip zinc iron coated structural steel annealed with guaranteed minimum yield strength. May have minor scratching.

It also can be painted. In comparison to galvanized steel the coating is harder and more brittle. Has no protective film. For example the coating designation g 90cifies spe there is a minimum coating weight of 90 ounces per square foot on both sides of the sheet.

The very fine matte finish acts like a primer and easily adheres to paint and it is very rust proof only white to dark grey marks appear if it comes in contact with water. Available in 4 x 10 and 5 x 10 sheets. 005 alliance steel s galvannealed steel sheet and coil service capabilities include slitting shearing blanking degreasing and brushing stretcher leveling and metallurgical support. This is preferred over galvanized if the metal is to be painted.
