New products, corrosion-protection techniques and specifications have meant an update to corrosion protection guidance for lighting columns was long overdue. A new PLG from the ILP, PLG26, is therefore now replacing previous guidance and offering updated comprehensive advice on all aspects of corrosion protection. Over the years lighting columns have been manufactured in many materials, shapes, sizes and protective finishes. The only common theme for all of them is that they are not fit and forget, far from it. Apart from structural inspection and testing, they have had a variety of protective finishes, so there has been a fair degree of variety in terms of the advice for maintaining those coatings. In the 1960s, steel lighting columns would probably have been primed in a variety of single-pack materials then finished off by painting on site with single-pack paint, often alkyd-type finishes.
