EN ISO 1461
- 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 below).

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’.
The British, European and International standard for hot-dip galvanizing is BS EN ISO 1461, which specifies a minimum coating thickness to be applied to steel in relation to the steels section thickness e.g. a steel fabrication with a section size thicker than 6 mm shall have a minimum galvanized coating thickness of 85 μm.
Hot dip galvanizing is a very simple process that provides long term corrosion protection to steelwork. Hot dip galvanizing process steps. Main steps within the galvanizing process include : cleaning cycle – decreasing and chemical clean; fluxing – helps to wet the surface of the steel; galvanizing – immersion of steel into bath of molten ...
Hot dip galvanizing is a relatively simple process to specify and is covered by a single standard EN ISO 1461. Galvanizers Association can provide detailed advice on compiling your specifications, as well as reviewing design details to maximise the benefits of galvanizing your steel.
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 with to promote a high-quality coating and ensure their steel design is suitable for hot-dip galvanizing.
While the steel is in the kettle, the iron in the steel metallurgically reacts with the molten zinc to form a tightly-bonded alloy coating that provides superior corrosion protection to steel. The hot-dip galvanizing (HDG) process consists of three basic steps: Surface Preparation. Galvanizing. Inspection.
Once considered only as a means of corrosion protection, hot-dip galvanizing is now specified for an array of reasons including lower initial cost, durability, longevity, availability, versatility, sustainability, and even aesthetics.
