Product Introduction

Q195 Galvanized Pipe: High-Performance Corrosion-Resistant Steel Tubing.

Engineered for Versatility: Construction, Machinery & Utility Systems

Q195 galvanized pipe is a ‌low-carbon steel pipe‌ with a minimum yield strength of 195 MPa, featuring zinc coatings (5–20 µm) for enhanced corrosion resistance. Ideal for harsh environments, it offers 3–5x longer lifespan than untreated steel in applications like agricultural machinery, warehouse frameworks, and water supply systems.


Certifications & Key Advantages

  • ASTM A53/A123 & GB/T 3091 Certified‌: Compliant with JIS G3442 and DIN 17162 standards.
  • Cost Efficiency‌: 40% lower lifecycle costs than stainless steel alternatives.
  • Custom Sizing‌: Thickness 0.1–300 mm (±0.15 mm), length up to 12 meters.
  • MOQ 1 Ton‌: Available in hot-dip galvanized (HDG) or electroplated (EG) finishes.

Technical Specifications

Mechanical Properties

Property Value Test Standard
