Loading ... Iron is used in various fields as an indispensable material for our social life. This iron has the property of causing "rust" as it is. Surrounded by the sea on all sides and in a humid environment, the economic loss caused by "rust" is said to amount to 4 trillion yen annually. It is also a serious problem that can lead to disasters. Therefore, it is socially important to establish sufficient and reliable rust prevention and corrosion prevention for steel products and structures. Watashin Kogyo Co., Ltd. is a factory specializing in iron rust prevention processing (hot-dip galvanizing). Toshin Kogyo's strengths What is hot dip galvanizing? Hot-dip galvanizing is a technique in which a steel material is dipped in melted zinc to form a zinc film on the surface. Galvanized steel does not rust or corrode. And unlike painting and electroplating, the "alloy layer" formed between zinc and iron strongly bonds zinc and iron, so the plating does not come off even after many years. Hot-dip galvanizing has two major features: "protective film action" and "sacrificial anticorrosion action".
