Philippine Tonan > Products > Hot-Dip Galvanizing (Cebu)

The hot-dip galvanizing of Philippine Tonan Corporation is one of the best and the biggest in region 7 specifically in Cebu. It gives services to one of the biggest shipbuilding in the country. We also handle the power industry requirements on their transmission line post, cable trays, control boxes and tower protectors here and abroad. Local steel structure fabricators also avail our services. This hot-dip galvanizing technology can also be used in the bridges and roads for railways, parking and transportation, sports stadium, entertainment areas and/or recreation like gymnasium. Our tank capacity is 6mLx1.2mWx1.5m H we can also accommodate longer than 6m but not more than 11m through our double dipping process. We use zinc with purity of 98.5% that gives us an edge in terms of quality. This type of technology can preserve a structure of more than 50 years. Hot-dip galvanizing is the process of coating iron, steel or aluminum with a thin zinc layer by passing the metal through a molten bath of zinc at a temperature of around 460 degrees Celsius. When exposed to the atmosphere, the pure zinc reacts with oxygen to form zinc oxide which further reacts with carbon dioxide to form zinc carbonate, a fairly strong material that stops corrosion. The process of hot-dip galvanizing results in a metallurgical bond between zinc and steel with a series of distinct iron-zinc alloys. The benefits of hot-dip galvanizing are as follows: lowest first cost, less maintenance, long life, reliability, toughest coating, its complete protection and faster erection time.
