Abstract
Trials are reported of zinc, lead and aluminium coatings exposed for 8·7 years at Lighthouse Beach, Lagos. Sprayed aluminium coatings gave good results. Zinc coatings applied by hot-dipping or electrodeposition were also successful but, after 8·7 years, sprayed zinc coatings were beginning to fail. Electrodeposited lead coatingscould not be recommended. The thickness of coating applied to the steel specimens was only 50–80 μm.
