21.5 Inch To 16 Inch Pre Galvanized Steel Pipes Q235 1.5mm to 12mm

Galvanized steel pipe is a steel pipe whose surface has been galvanized. This treatment significantly improves the pipe's corrosion and rust resistance, extending its service life.

• Appearance: Surface is typically silvery-white with metallic luster and snowflake-like or fish-scale-like crystalline patterns. After use, it may turn dark gray due to oxidation.
• Coating: Available in hot-dip galvanizing and electro-galvanizing (cold galvanizing). Hot-dip galvanized pipe is most common, with thick zinc layer, strong adhesion, and excellent corrosion resistance.
• Weight: Slightly heavier than black pipe of same specifications due to added weight of zinc layer.
• Corrosion Resistance: Zinc layer effectively isolates steel substrate from air and water corrosion. Even with minor damage, zinc protects iron through cathodic protection.

Galvanized steel coil products are mainly used in construction, light industry, automobile, agriculture, animal husbandry, fishery and other industries. Applications include building roofs, highway guardrails, sheet metal processing, roof grilles, household appliance enclosures, ventilation ducts, chimneys, kitchen utensils, grain storage and transportation, frozen processing of meat and aquatic products, etc.
