Avoiding galvanic/bimetallic corrosion between aluminium decking or balcony components and galvanised steelwork

One of the most common scenarios that AliDeck aluminium decking and balcony component products are used in is on steel-framed balconies, manufactured from galvanised steelwork.

With the two metals in close proximity once installed there is the risk that galvanic corrosion may occur unless suitable precautions are taken.

Galvanic corrosion (also known as bimetallic corrosion) is an electrochemical process that occurs when dissimilar metals are in contact via an electrolyte, with one of the metals corroding much more rapidly than if the two metals were not in electrical contact. An example of such a scenario would be aluminium connected to steel and doused in rainwater.
