Products Description
DN100 hot-dip galvanized steel pipe is a versatile and robust solution for heavy-duty industrial, commercial, and municipal applications. This size (4 Inch Nominal Pipe Size) is one of the most commonly used in water distribution, construction frameworks, and scaffolding systems. Manufactured to international ASTM standards, it undergoes a rigorous hot-dip galvanizing process that provides a thick, uniform zinc coating for exceptional corrosion resistance and long service life, even in harsh environments.

Products Advantages
Precise Sizing: DN100 (4" NPS) with consistent outer diameter (114.3mm) ensures perfect compatibility with all standard fittings, valves, and flanges.
Superior Corrosion Protection: The hot-dip galvanizing process creates a metallurgical bond between the zinc and steel, offering complete internal and external protection against rust and corrosion.
High Pressure & Load Capacity: The substantial wall thickness (e.g., Sch 40: 6.02mm) provides excellent mechanical strength, high internal pressure rating (PSI), and significant load-bearing capacity for structural applications.
Long Life & Low Maintenance: The combination of high-tensile steel and a durable zinc coating drastically reduces maintenance needs and replacement costs, offering a superior return on investment.
Ready for Installation: Available with threaded (T&C) ends for easy, screw-on assembly, saving time and labor costs on site.
Products Applications
