Dear,

Are you asking of measuring the thickness of the galvanized coating of the entire, including the steel sheet? In case you are refering to the galvanize coating only.

 

Size, shape and number of pieces to be tested dictates the method to be used. Specified test methods are either destructive or non-destructive. There are four ways to measure the thickness of galvanizing...

1. Magnetic Thickness Gauges

2. Stripping & Weighing

3. Weighing Before & After Galvanizing

4. Optical Microscopy (ASTM B 487)

 

The most practical test is the non-destructive method utilizing the magnetic principle for determining coating thickness. It is...

• Non-destructive

• Simple, Fast and Inexpensive

• Complies with recognized international standards including ASTM E 376, CSA G 164-M, ISO 2808
