Hot Dip Galvanising for Steel Corrosion Protection
Singapore, August 18, 2011.
By Dr Michael Ainsley, PHD from University of Adelaide
Super Galvanising Singapore invited DR Mike Ainsley to conduct a sharing session of an overview of the Hot Dip Galvanising process, the benefits of this coating method and its application as illustrated with both Global and Regional examples.
Corrosion mitigation is a critical consideration for many steel structures and is particularly relevant to Singapore and environs given such corrosion-inducing factors as high ambient temperatures, high humidity/rainfall levels and marine proximity.
Hot Dip Galvanizing (HDG), which involves applying zinc coating to steel, has gained throughout the world an enviable and proven track-record of providing a reliable, durable and cost effective solution for corrosion protection for many steel applications. Additionally, the benefit of this coating method are now well-recognized as contributing significantly to sustainable construction from an environmental perspective.

Using Hot Dip Galvanised Reinforcing Steel
by Professor Stephen R Yeomans, University of New South Wales, Canberra, Australia.
Super Galvanising Singapore invited Professor Stephen R Yeomans to conduct a sharing session of the corrosion of steel reinforcement in concrete and strategies that can be adopted to avoid this insidious problem. During the session, Professor Yeomans discussed about how the corrosion of reinforcement is the most likely cause of the lack of durability of concrete and represents a significant expense in the maintenance and repair of concrete structures. If allowed to progress, reinforcement corrosion may also affect the structural integrity of the concrete itself.Galvanizing is a well-known and widely-utilized method for the protection of steel reinforcement embedded in concrete. The history of the use of galvanizing steel in concrete extends over a period of more than 70 years. Recent experience indicates an increasing use of galvanized steel in a variety of concrete structures exposed to a range of environmental conditions including severe topical marine and industrial environments.
The seminar reviews the characteristics and use of hot-dip galvanized reinforcement. It covers its metallurgical characteristics and corrosion performance, design considerations, bond and load capacity, fabrication and handling, and showcases a range of world-wide applications. A key source of information to support the seminar is Galvanized Steel Reinforcement in Concrete, SR Yeomans (Editor), Elsevier, 2004. An overview paper extracted from the various chapters of this book is provided for quick reference.
