Taken: 1951-1953, Ref: M1951

Hot-dip galvanising’. Photo (18) from a series illustrating the making of a window. From page 20 of catalogue. The caption says ‘Hot-dip galvanizing. There are eight separate operations in the hot-dip galvanizing process. Here is shown the actual dip into the bath of molten spelter. This contains over one hundred tons of metal. The frames are slowly immersed and withdrawn, remaining submerged until they have reached the temperature of the molten zinc. It is strongly recommended that whenever possible Crittall windows should be hot-dip galvanized’. Probably at Braintree. See link for notes on the catalogue.
