Color coated galvanized plate measure coating thickness

CAMELSTEEL will introduce you some methods to measure the coating thickness of color coated galvanized plate.

This method is suitable for measuring the thickness of color coated galvanized plate and steel belt surface coating thickness.

The method stipulates four ways to measure the coating thickness of color coated galvanized plate, they are magnetic thickness tester method, handheld micrometer method, metallographic microscope method and drill-hole destructive microscopy observational method.

1. Magnetic thickness tester method: It is suitable for measuring coating thickness of color coated galvanized plate taking cold-rolled plate and galvanized plate as substrate, except that the coating thickness is less than 3μm.

2. Handheld micrometer method: It is suitable for measuring coating thickness of color coated galvanized plate of which the substrate can be all kinds of material. Yet it is not suitable for measuring thickness of coatings which are easy to distort under the load of micrometer measurement device.

3. Metallographic microscope method: It is suitable for measuring coating thickness of color coated steel coil of which the substrate can be all kinds of material.

4. Drill-hole destructive microscopy observational method: It is suitable for measuring coating thickness of color coated steel coil of which the substrate can be all kinds of material.
