coating thickness gauge pce instrumentsthe pcect 28 coating thickness gauge for cars is for measuring the thickness of paint and plastic on ferrous or nonferrous materials without damaging the coating 39;s surface. the coating thickness gauge stands out due to its high range of measurement. measurement range: 0 1250 µm / 49.2 mils galvanized coating thickness gauge fob portable hardness testercoating thickness gauges is designed for measuring the thickness of coating. the feature for this meter is fast , nondestructive and accurate. galvanized coating thickness gauge portable coating thicknes galvanizing thickness measurement resources defelskosteel 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 the surface of a fabricated steel part to provide corrosion protection. the final step in this process is the inspection of: 1. coating thickness 2. visual appearance 3. adhesion 4. uniformity the thickness of the galvanized coating is directly related to: 1. service life 2. amount of corrosion protection 3. quality a thicker coating of galvanize results in a longer service life for the coated part. consequently, inspection of coating thickness is the single most important see full list on defelsko the size, shape and number of pieces to be tested will dictate the appropriate test method. specified test methods are categorized as either destructive or nondestructive. there are four ways to measure the thickness of galvanizing: 1. magnetic principle thickness gages 2. stripping and weighing 3. weighing the part before and after galvanizing 4. optical microscopy (astm b 487) the most practical test is the nondestructive method utilizing the magnetic principle for determining coating thickness. this test is 1. nondestructive 2. simple, fast, and inexpensive 3. complies with recognized international standards including astm d7091, csa g 164m and iso 2808 because it is nondestructive, magnetic thickness measurementis the most common method of evaluating galvanizing coating thickness. see full list on defelsko coating thickness gages that operate on a magnetic principle are designed to measure nonmagnetic coatings applied to ferrous metals. the three most common types of magnetic principle thickness gages fall into one of two categories: see full list on defelsko duplex coating systems use a combination of two corrosion protection systems typically paint or powder coating over galvanized steel (hotdip, electro or zinc spray metallizing). the corrosion protection which results from a duplex coating system is superior to either protection system used independently. defelskos positector 6000 fndscoating thickness gage nondestructively measures the individual thicknesses of both the paint and the zinc galvanize layers in a duplex coating system with a single reading. see our duplex coating system thickness measurementapplication note to learn more. see full list on defelsko magnetic coating thickness gages report measurement values in units of linear distance, not coating weight. however, the gage reading can easily be converted to an expression of coating weight. example conversions example a:imagine you take a measurement on a steel coil coated with zinc galvanize using a positector 6000 f gage and obtain a singleside thickness reading of 0.35 mils. this can be easily converted to oz/ft² using the following method: 1. multiply the gage reading of 0.35 mils by 2 to account for both sides of the panel (0.70 mils) 2. multiply 0.70 by a factor of 0.5938 to convert to oz/ft² (0.4157 oz/ft²) 3. 0.4157 oz/ft² of zinc galvanize indicates g40 weight (0.40 oz/ft² minimum average, total of both sides per astm a 653) example b: alternately, you can quickly confirm that a galvanized steel sheet meets a specific coating weight. according to astm a 653, a g90 coating designation means the weight of zinc on both sides of a steel sheet is 0.90 oz/ft². however, a m see full list on defelsko q: why does it seem that i never obtain the same gage reading twice? a: although the galvanized surface may appear smooth, microscopic surface roughness exists on both the zinc and steel. therefore, the best representation of coating thickness is obtained by averaging a series of readings as per astm a123. q: can i use a magnetic coating thickness gage to measure coating weight? a:magnetic coating thickness gages report measurement values in units of linear distance, not coating weight. however, the gage reading can easily be converted to an expression of coating weight using a conversion table or multiplication factor. q: what should a coating thickness gauge read on a g90 galvanized coating? a: according to astm a 653, a g90 coating designation means the weight of zinc on both sides of a steel sheet is 0.90 oz/ft2 a magnetic thickness gauge measures only one side. therefore: 1. 0.45 oz/ft2x 1.684 = 0.76 mils per side 2. 0.45 oz/ft2x 42.78 = 19 microns per side see full list on defelsko excerpts from astm a123standard specification for zinc (hotdip galvanized) coatings on iron and steel products: 1. the specimen coating thickness shall be the average of a minimum of 5 readings at widely dispersed points. 2. this average value shall be not less than one coating thickness grade lower than the value listed in the appropriate specification. 3. thickness should be between 1.4 and 3.9 mils (35 and 100 µm) depending on the coating grade. astm e 376standard practice for measuring coating thickness by magneticfield or eddycurrent (electromagnetic) examination methods astm a123/a123mstandard specification for zinc (hotdip galvanized) coatings on iron and steel products astm a153/a153mstandard specification for zinc coating (hotdip) on iron and steel hardware astm a653/a653mstandard specification for steel sheet, zinccoated (galvanized) or zinciron alloycoated (galvannealed) by the hotdip process astm a767/a767mstandard specification for zinccoated (galvanized) stee see full list on defelsko galvanized coating thickness gauge fob portable hardness testercoating thickness gauges is designed for measuring the thickness of coating. the feature for this meter is fast , nondestructive and accurate. galvanized coating thickness gauge portable coating thicknes coating thickness gauge grainger industrial supplyget a precision coating thickness gauge from grainger to help measure the thickness of paint plating, coatings and galvanizing on ferrous and nonferrous metals. find mechanical and electronic coating thickness gauges with a variety of measuring ranges. some models include a holster, a carrying case or both. measurement of the thickness of hot dipped galvanizing kta jun 01, 2020 · if structural shapes greater than 5/8 inches in thickness are being galvanized, table 1 indicates that the coating grade is 100. table 2 indicates that the galvanizing thickness of coating grade 100 is 100 microns or 3.9 mils. the weight of the galvanizing is 705 grams/square meter or 2.3 ounces/square foot. thickness gauges mcmastercarrcoatingthickness gauges use these gauges to measure nonmagnetic coatings such as paint, galvanizing, plating, and enamel on steel. economy coatingthickness hot dipped galvanized coatings: g140 vs. g90 vs. g60nov 18, 2010 · g60 is a hot dip galvanizing specification for .6 oz total weight of zinc per square foot (approx. 0.0005quotthickness per side), whereas there is a different spec for electrogalvanizing wherein 60g60g means each side is plated to a weight of 60 g/m2. what is a coating thickness gauge?a coating thickness gauge (also referred to as a paint meter) is used to measure dry film thickness. dry film thickness is probably the most critical measurement in the coatings industry because of its impact on the coating process, quality and cost. galvanized coating thickness gauge best galvanized coating galvanized coating thickness gauge, metal painting thickness meter, plating thickness test this device is a portable meter. it is capable of measuring coating thickness quickly, precisely and without injury, both for the laboratory and engineering
