Galvanized vs. Pre-galvanized Pipes: Pros and Cons
1. Galvanized Pipes (Hot-Dip Galvanized) Advantages: Superior Corrosion Resistance: Thick zinc coating (typically ≥85μm for large pipes) provides long-term protection in harsh environments like coastal areas or chemical plants, with a lifespan of 20–50 years26. The zinc-iron alloy layer formed during hot-dipping offers sacrificial anode protection, preventing rust even if the surface is scratched24. Enhanced […]
