Products Description
A 2-inch galvanized steel pipe is a steel pipe with a nominal diameter of 2 inches that has been coated with a layer of zinc to protect it from corrosion. Here's a breakdown of its key features:
Material & Coating:
Base Material: Made from carbon steel.
Galvanization: Coated with zinc (via hot-dip or electro-galvanizing) to prevent rust and extend lifespan.

Products Advantages
A 2-inch galvanized steel pipe is coated by immersion in molten zinc, providing a protective barrier against corrosion. This zinc layer shields the steel from environmental wear, significantly extending the pipe's lifespan.
- The zinc coating acts as a sacrificial barrier, protecting the steel from rust, moisture, and harsh weather. Ideal for outdoor use (e.g., fencing, scaffolding) and humid environments.
- Lasts 20–50+ years with minimal maintenance, reducing replacement costs. Outperforms untreated steel in durability.
- Withstands high pressure, impacts, and mechanical stress. Suitable for structural applications (e.g., handrails, support columns).
- Lower long-term costs than stainless steel or copper due to its affordability and longevity. Requires no additional coatings or treatments post-installation.
FAQs
1. What is a 2-inch galvanized steel pipe?
A steel pipe with a nominal diameter of 2 inches (actual OD: ~2.375 inches or 60.3 mm) coated with zinc to prevent rust. Used in plumbing, construction, and industrial applications.
2. What are the types of 2-inch galvanized pipes?
Seamless: No weld joints, stronger, used for high-pressure systems.
ERW (Electric Resistance Welded): More affordable, common in plumbing and fencing.
Hot-Dip vs. Electro-Galvanized: Hot-dip offers thicker zinc coating for better corrosion resistance.
3. What are the standard lengths available?
Typically 6 meters (20 feet), but custom lengths (e.g., 12 ft, 24 ft) may be available.
4. What is the weight of a 2-inch galvanized pipe?
Schedule 40: ~5.79 kg/m (3.89 lb/ft).
Schedule 80: ~8.63 kg/m (5.80 lb/ft).
5. What pressure can it handle?
Schedule 40: ~300 PSI (varies by material and temperature).
Schedule 80: ~500 PSI.
