What is minimum thickness of steel coat?
What is minimum thickness of steel coat? As indicated in Table 1, the total coating mass on heavier steel sections normally is a minimum of 600 grams of zinc per square meter of surface area (g/m²) which is equivalent to about 85μm thickness....COATING THICKNESS AND FACTORS INFLUENCING THICKNESS.Steel thickness mmAverage coating thickness minimum μmAverage coating mass minimum g/m²>3 to ≤670500>685600 How thick should galvanized coating? Typical galvanized coatings range from 3-8 mils (75-200 mi- crons) thick. When designing and detailing tapped holes, the increased thickness is important. Best practice suggests that the hole be tapped after galvanizing, removing the coating...
