●Hot Dip Galvanized Steel Square and Rectangular Pipe
High-Zinc Galvanized Steel Pipes: Superior Corrosion Protection for Demanding Applications.
High-zinc coated hot-dip galvanized steel pipes are corrosion-resistant steel tubes with a metallurgically bonded zinc layer, achieved through immersion in molten zinc (typically 98-99% pure zinc at ~450°C). This process creates a dual-protection system:
►A physical barrier isolating steel from environmental factors
►Sacrificial anode protection where zinc corrodes preferentially to stee
