The Hot Dip galvanizing process has been around for 150 years & is a means of protecting steel products against oxidation & corrosion. Galvanizing protects a steel material by means of coating the steel work with a layer of zinc.
The galvanizing process is a staged process that includes hydrochloric acid treatment to ensure that the surface chemically clean prior to zinc coating. The steel work is then fully immersed into a tank containing liquid zinc held and controlled at 450 deg. C. The zinc reacts with the steel surface which forms a series of zinc iron alloy layers which are metallurgically bonded to the steel substrate. This gives a coating which even when damaged in small areas, will provide an impenetrable layer to the steel substrate. In comparison to other corrosion protection systems, Hot Dip Galvanizing provides protection to both side surfaces of hollow sections. For this to be successfully carried out, fabrications need to be vented allowing the zinc to enter at the lowest point and for the free passage of air to escape at the highest point (see above). This is a most important consideration at the design stage of a fabrication, as inadequate venting can lead to potential production problems.McArthur Group offer specialist Galvanizing services from 2 locations in the UK, namely:
