Hot Dip Galvanizing

​

​Although galvanization can be done with electrochemical and electro-deposition processes, the most common method currently used is hot-dip galvanization.

​

​Hot-dip galvanizing is a form of galvanization. It is the process of coating iron or steel with a thin zinc layer, by passing the steel through a molten bath of zinc at a temperature of around 860 °F (460 °C). When exposed to the atmosphere, pure zinc reacts with oxygen to form zinc oxide, which further reacts with carbon dioxide to form zinc carbonate, a dull grey, fairly strong material that stops further corrosion in many circumstances, protecting the steel below from the elements.

​

​International Galvanizing process is fully automated to control temperatures and coatings and assure proper quality.

Spin Galvanizing

​

International Galvanizing is also equipped with ceramic high temperature zinc ovens suitable for hot dip galvanizing of a whole variety of smaller fastening materials, such as bolts (from m8), nuts, clips, clamps, wire nails, threaded rods and anchors.

​

This procedure is of particular interest in various markets such as machine building, steel construction, wind turbine industry and in the automotive and energy sectors.

​

The modern spin process allows hot dip galvanizing of even smaller sizes of bolts and nuts without the fit being compromised. Products with a screw thread of between m10 and m100 can be hot-dip galvanized without a problem. The screw thread remains available over the complete length, even up to 3,000 mm in length.
