Coating Thickness. There are two methods for measuring the zinc coating thickness of hot-dip galvanized steel; a magnetic thickness gauge and optical microscopy. The simplest and non-destructive way is to utilize a magnetic thickness gauge, as optical microscopy is a destructive test only used to resolve measurement disputes. Gauge Thickness and Weight Chart for Sheet Metal ProductsKynar Galvalume (Steel) for metal roofing and gutters:24 gauge. Kynar Aluminum for metal roofing:0.032" or 0.040".

Hot Dip Galvanized Information Sheet No - HDGASAHot Dip Galvanized Information Sheet No.7 Hot Dip Galvanizing of Nuts and Bolts Reference:SANS 121 (ISO 1461:2009) and ISO 100684:2004 Corrosion protection of carbon steel fasteners is generally achieved through the application of a coating (barrier protection), be it in the form of a paint system or through the use of a metallic coating.
Steels in thickness less than 3mm are unlikely to be significantly affected. The galvanizing process involves immersion in a bath of molten zinc at about 450°C. Heat-treated or cold-worked steels can be tempered by the heat in the hot dip galvanized bath and lose some of any increased strength obtained by heat treatment or cold working.

May 28, 2009 · One of my client has been asking me to restrict the coating thickness limit Of galavanizing to 227 microns . For a thickness of steel greater than 10mm with silicon content of 0.15- 0.35 %. His concern his that there is a possible chance of flaking beyond 227 microns . But is that true for the above specs and if yes .
