The Company organized a seminar on ?Hot Dip Galvanizing to Combat Steel Corrosion, with a special focus on Concrete Reinforcing Steel? for engineers in galvanizing industry and architects. Mr. Bernard Tonnon, Managing Director, opened the seminar and invited Mr. Doug Rourke from the International Zinc Association (IZA) and Dr.Satian Niltawach as speakers. The seminar was held on November 9, 2006.
Here’s some of the opening speech of Mr.Bernard Tonnon
This meeting reflects the importance the International Zinc Association (IZA) and Padaeng Industry give to the support of the galvanizing industry in Thailand.
To this end, IZA and Padaeng Industry are determined to join hands in bringing timely technical information to you, so that all undertakings in this field may meet international standards for the benefits of the Thai society.
Hot dip galvanizing has been for decades the best and cheapest way to protect steel in most applications. Even if largely ignored by the public, this industry has been one of the pillars that support the development and the infrastructure of most advanced countries. Of course, Thailand has already earned its place in that field among advanced countries but you will agree with me that there is still a potential for further progress.
More and more end-user markets become aware of the costs of corrosion, and the increasingly global market will extend that trend to all regions of the world where corrosion occurs.
As you know, this seminar will focus on galvanized steel reinforcing bars for concrete.
In recent construction ventures, the quality of black steel bars sometimes leaves much to be desired in terms of bonding strength with concrete. There are many cases where corrosion of the steel bars occurs inducing cracking and spalling of concrete. All this leads to a shorter service life of concrete structures and a reduction of safety in those structures.
It has now been established that galvanized steel bars are much superior than black steel bars in the task of reinforcing concrete. I believe that galvanized rebar will gain more and more momentum as time goes by. When you know that more than 100 million tons of reinforcing steel are used every year in the world and that only a minor fraction is galvanized, this is a major target for improvement??
