The hot dip galvanisation process
Once we receive your items, we’ll prepare them by degreasing to remove any soil and grease. Next we’ll ensure a good clean surface is achieved by using acid to strip the steel back – a process called ‘pickling.’ Then, to help with the chemical reaction which occurs during galvanisation, we apply a fluxing solution.
Only when these three steps have been performed to our satisfaction will the galvanising process begin. The items are dipped into a bath of molten zinc at a temperature of around 460°C. This metallically bonds a layer of zinc to the steel or iron. The products are then cooled in a quench tank before being delivered to or collected by our customers.
