Preface

Steel is an essential and vital resource in today's human life. However, because of its own characteristics, "rust" is constantly accompanied by us, and our resources are lost all the time - steel. In particular, Taiwan's "rust" problem is worse than any other country in the harsh environment of Taiwan's maritime monsoons that are hot and humid.

Advanced countries have long noticed the seriousness of "rusting". It is estimated that losses caused by corrosion prevention are estimated at about 3.5% of gross national product (GNP) in Japan in one year and 4.2% in the United States, 3.5% in Britain and 3% in Germany, while Taiwan far surpassed the above countries. For example, with Japan's 3.5%, we unknowingly lost NT $ 586.65 billion in 2015 (Gross national product in 2015 was NT 16.775 billion). Therefore, advanced countries have set up relevant anti-corrosion technology research institutions to take effective measures to avoid or reduce their losses. However, at present it seems that there is no major body in our country to face this issue squarely. Therefore, everywhere we can see the "rusty" landscape caused by the poor anti-corrosion technology or the wrong anti-corrosion method. It is very distressing.

Hot-dip galvanized anti-corrosion technology is currently the most advanced countries, the most widely used, but also the most effective method of atmospheric corrosion, its performance, characteristics and economic benefits, are mentioned in this introduction. Hope that by the introduction of this briefing, so that everyone on the hot dip galvanized anti-corrosion methods, have a deeper understanding, and to be adopted. Let us hope that as soon as we can see the calm and steady "zinc" in various parts of Taiwan, we will fill every corner of our lives and shoulder the heavy responsibility of safeguarding our human being with limited resources.

The use of hot-dip galvanized has more than 170 years of history, and its principle has not changed. And due to numerous research reports for its work processes for a detailed review, so from the most primitive wet zinc plating has evolved to dry and continuous operation. Its anti-corrosion effect is also recognized as the best, and the most cost-effective. It is estimated that there are about 20,000,000 tons of hot dip galvanized steel in the world each year and the maintenance value of limited human resources is hard to estimate.

The use of hot dip galvanized steel in advanced countries has been very extensive. For example, electricity, telecommunications, roads, transportation, bridges, bays and buildings are all used. Therefore, "there is hot dip galvanizing in iron areas" should not be overemphasized. Taiwan is in a subtropical humid maritime environment where the corrosion problem is more serious than that of other countries. However, due to the lack of alertness to anti-corrosion problems, the landscape of abandoned steel due to corrosion can be seen everywhere. Thinking deeply.

Benefits of Hot-dip Galvanizing

■  Longer Lasting Duration
Longer lasting duration: High corrosion resistance, and much more durable than other anti-corrosion solutions.

■  High Economic
Highly economical: Steel structures that underwent hot-dip galvanization do not need regular maintenance; extremely economical.

■  Excellent Adhesion
Excellent adhesion: Hot-dip galvanization creates a thicker and stronger alloy coating that can withhold normal wear and tear during the shipping process and the coating is unlikely to fall off.

■  Cathodic Protection
Cathodic protection: By sacrificing the zinc anode, even if the outer layer is damaged the underlying rust is controlled and will not erode.

■  High Reliable
The galvanized item can be protected outdoor or indoor, all other anti-corrosion solutions have blind spots that cannot be protected.

■  Rapid Construction Period
Steel structures that have gone through hot-dip galvanization can be installed quickly even during rainy days, thus saving valuable time.
