National Standard Galvanizing Thickness for Hot-Dip Galvanized Cable Trays
Tray Sheet Metal Thickness: Typically, the side plates and base plates of cable trays range from 1. Therefore, the local zinc thickness should be no less than 45µm (corresponding to a coating mass of no less than 325g/m²). The basic specification for hot dip galvanized coatings on iron and steel articles is defined by a single standard, EN ISO 1461 'Hot dip galvanized coatings on iron and steel articles – specifications and test methods'. However, there are some exceptions to this standard (see thicker coatings. There are certain specifications that have been developed for hot-dip galvanizing in order to produce a high-quality coating. There are three main standards that govern hot-dip galvanized steel, and a handful of supporting specifications that design engineers and fabricators should become familiar. This standard specifies the local thicknessand mean coating massbased primarily on the steel thickness. This standard contains coating thickness requirements as shown in Table 1 which will typically be suficient t achie steelwork may be grit blasted prior to galvanizing. The excellent qualities of the materials come from their protective zinc coating.
