Protect heat exchangers from root corrosion with Hot-Dip Galvanized helical finned tubes. Immersing tubes in a molten zinc bath at 440°C–465°C creates a seamless metallurgical alloy bond. This 360° total coverage prevents rust micro-gaps, resists thermal expansion, and lowers maintenance costs. Ideal for air-cooled heat exchangers, boilers, and petrochemical systems.
