Some results are removed in response to a notice of local law requirement.For more information,please see here.People also askWhich is better G90 or G60 coating?Which is better G90 or G60 coating?Similarly,a G90 coating is approximately 50% thicker than a G60 coating,and thus would be expected to perform 50% better (in terms of time to 10% rust).Limits on maximum acceptable coating weights for an application are usually given by other factors such as cost or formability.GalvInfoNote Understanding Coating Weight Designations for How long will a galvanized G40/G60/G90 coating last

How long will a galvanized G40/G60/G90 coating last? How long the galvanization lasts depends primarily on the site conditions (i.e.temperature,exposure,moisture,etc.),with a linear relationship between coating thickness and ability to resist corrosion.

The minimum protective coating requirement of ASTM C645 is G40.To explain the meaning of this coating designation,the alpha character G indicates that the coating is galvanized (zinc-based),and the numeric character refers to the weight of zinc on the surface of the steel sheet in ounces per square foot units.Using G40 as an example,theHOT-DIP GALVANIZED (HDG) SHEET STEELG60 0.60 0.20 0.50 G40 0.40 0.12 0.30 G30 0.30 0.10 0.25 CORROSION PROTECTION HDG sheet steel protects well against corrosion.Figure 1 shows typical results of outdoor exposure testing on G90 HDG coated steel sheet.The length of time to red rust is proportional to the thickness of the zinc coating.For heavy gauge steel,thicker HDGHOT-DIP GALVANIZED (HDG) SHEET STEELG60 0.60 0.20 0.50 G40 0.40 0.12 0.30 G30 0.30 0.10 0.25 CORROSION PROTECTION HDG sheet steel protects well against corrosion.Figure 1 shows typical results of outdoor exposure testing on G90 HDG coated steel sheet.The length of time to red rust is proportional to the thickness of the zinc coating.For heavy gauge steel,thicker HDG
