There are many references to specifying hot dip galvanizing throughout the National Building Specification (NBS) system, the main location being G10 – Structural steel framing.

As coating life expectancy figures quoted are based on the minimum coating thickness they are therefore usually very conservative.ĮN ISO 1461: coating minimum masses/thickness on articles that are centrifuged Actual coating weights are often much more than the minimum specified in the standard. The actual thickness of galvanized coating achieved varies with steel section size, surface profile and surface composition. This is an important advantage of the galvanizing process a standard coating thickness is applied almost automatically. When hot dip galvanizing is specified, the surface of the steel is completely covered with a uniform coating whose thickness is determined principally by the thickness of the steel being galvanized (see Graph 1 below). What is the thickness of the hot dip galvanizing coating? It is now superseded by (BS) EN ISO 1461. However, there are some exceptions to this standard (see thicker coatings below).īS 729 was the old British galvanizing standard for hot dip galvanizing. 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’. To ensure the best quality and technical back-up service, it should be stated that the work be "processed by a member of Galvanizers Association".
