Galvanizing Thickness Measurement | Resources | DeFelsko

Steel corrodes when an electrolyte (such as water) connects anodes and cathodes on a steel surface. The formation of the corrosion cell causes a flaky iron oxide known as rust. To avoid rust, something must prevent the formation of the corrosion cell. Two common methods for preventing corrosion on steel are: 1. Cathodic protection (by using a sacrificial anode). 2. Creating a barrier to block electrolytes from contacting the steel. Galvanizingis the process by which a sacrificial anode layer of zinc is applied to thSee more on defelsko hot dipped zinc coating 20 gauge sheetGalvanized Steel Berlin MetalsThe corrosion resistance of the G type is directly related to the amount of zinc coating, i.e., G90 will resist corrosion to the base metal longer than G30.
