Introduction to New Galvanised Drum Manufacturing Processes

Having operated within this industry for many years, manufacturers face diverse clientele and an increasingly competitive market. Beyond maintaining vigilant awareness of the latest developments, the remaining time is dedicated to enhancing product performance – with advancements in galvanisation techniques being one such focus. In recent years, our German manufacturer has recognised that merely producing iron drums is insufficient for market survival. The currently popular coated iron drums and painted iron drums are invariably galvanised.

Galvanised Iron Drum Material: Zinc readily dissolves in acids and also in alkalis, hence its classification as an amphoteric metal. Galvanised iron drums undergo minimal change in dry air. In humid conditions, a dense basic zinc carbonate film forms on the surface. However, galvanised iron drums exhibit poor corrosion resistance in atmospheres containing sulphur dioxide, hydrogen sulphide, or marine environments.

At elevated temperatures and high humidity, particularly in the presence of organic acids, the zinc coating is highly susceptible to corrosion. The standard electrode potential of zinc is -0.76V. For steel substrates, the zinc coating acts as an anodic layer, primarily preventing steel corrosion. Its protective efficacy is highly dependent on coating thickness.

The above outlines the advantages of galvanised iron drums. We hope this proves helpful. Should you have further queries, please telephone or leave an online message, and we shall respond promptly. Next time, we shall explore the selection of galvanised materials for iron drums. Should you possess superior countermeasures or processing methods, we would be most grateful for your guidance.
