Inspection of the Hot Dipped Galvanizing Process
WebIt has a galvanized wire mesh of an unknown original thickness added for extra security. Figure 7: The same fence from another angle, showing the galvanizing on the wire mesh has broken down and rust has stained the entire structure, while the tubular after-fabrication galvanized fence is still rust free. WebIf what we are interested in is the coating thickness, why do ASTM standards not use thickness measurements? The answer is simply that it is difficult to directly measure the thickness accurately and precisely. For example, a G90 coating contributes about 1.6 mils (0.0016 inches, or about 42 microns) to the total thickness of the coated sheet. fait divers orthographe
