Stainless & Galvanized Steel Pipe Corrosion Protection in Production
During production, stainless steel pipes maintain a shiny appearance due to their natural corrosion resistance. However, galvanized steel pipes rely on zinc coating for protection. The longevity of galvanized products depends on coating thickness, quality, and environmental conditions.
Key Differences Between Regular Steel & Galvanized Steel:
Regular Steel – Prone to rust and corrosion when exposed to moisture/air.
Galvanized Steel – Zinc coating provides short-to-medium-term corrosion resistance, but does not last forever.
Over time (especially after 10+ years), rust may still form.
Additional paint protection (primer + topcoat) is required for long-term durability.
Challenges in Painting Galvanized Steel:
Smooth Surface – Standard paint struggles to adhere to galvanized steel, leading to peeling and poor corrosion resistance.
Solution: Use specialized primer + topcoat systems for maximum adhesion and durability.
Recommended Paint System for Galvanized Steel
Surface Preparation (Critical Step!)
Lightly sand/abrade the galvanized surface to create roughness for better paint adhesion.
Remove dust, grease, and oxidation before
