TG26:22 Galvanic Corrosion of Aluminium Tubes and Prefabricated Beams - Digital Download (PDF format)
This guidance note provides clear practical advice on galvanic corrosion affecting aluminium tubes and prefabricated beams, helping companies identify risks and prevent material degradation.
This 2 page technical guidance is aimed at scaffolding companies, designers, and inspection personnel. It explains how galvanic corrosion can occur when aluminium components come into contact with dissimilar metals in the presence of moisture, potentially leading to loss of strength and premature failure. The guidance outlines risk factors, typical scenarios, inspection indicators, and preventative measures such as material separation, protective coatings, and storage practices. By following this guidance, companies can reduce corrosion-related damage, extend the service life of aluminium components, and maintain safe and compliant scaffolding systems.
