Customizable Galvanized Pipe | Tailored Sizes for Construction

Product Overview

Our hot-dip galvanized pipes are precision-engineered for structural and industrial applications, offering unparalleled corrosion resistance and durability. Designed to meet ASTM A53, EN 10255, and ISO 1461 standards, these pipes are ideal for welding galvanized pipe projects, square galvanized pipe frameworks, and long-span installations like 20 foot galvanized pipe systems. With a zinc coating density of ≥130 g/m² and customizable dimensions, our products excel in harsh environments, including coastal and high-humidity regions.

Key Properties

  1. Corrosion Resistance
    The zinc layer forms a sacrificial barrier against rust, even in saline or acidic environments. For welding galvanized pipe joints, post-weld galvanizing ensures seamless protection.

     

  2. Mechanical Strength

    • Tensile Strength: ≥500 MPa (ISO 6892-1)
    • Yield Strength: ≥300 MPa
    • Bend Resistance: Withstands 90° bends without cracking (EN 10242).
    • Impact Toughness: 27 J at -20°C (ASTM A370).

  3. Customization
    Tailor square galvanized pipe dimensions (e.g., 20x20mm to 400x400mm) and wall thickness (0.8–25mm) for scaffolding, greenhouses, or structural frames.

     

Weight Calculation

Calculate pipe weight using:

Where:

  •  = Outer Diameter (mm)
  •  = Wall Thickness (mm)
  •  = Length (m)
    Example: A square galvanized pipe of 30x30mm (WT=2mm, 6m length) weighs ≈8.9 kg.

Marking & Identification

Pipes are laser-etched with:

  • Manufacturer’s logo and batch number
  • ASTM/EN standard (e.g., ASTM A53)
  • Dimensions (OD, WT, length)
  • Coating type (HDG for hot-dip galvanized).

Why Stainless Steel Rusts?

While stainless steel is corrosion-resistant, rust can occur due to:

  1. Damaged Passive Layer: Scratches or abrasive cleaning disrupt the chromium oxide film.
  2. Chloride Exposure: Coastal or de-icing environments cause pitting corrosion.
  3. Galvanic Corrosion: Contact with carbon steel or copper triggers electrochemical degradation.
  4. High-Temperature Oxidation: Prolonged exposure above 400°C weakens the alloy.

Applications

  • Structural Frameworks: Square galvanized pipe for scaffolding, warehouses, and bridges.
  • Gas Distribution: Welding galvanized pipe systems with NSF 61 certification for methane/LPG.
  • Agricultural Use: 20 foot galvanized pipe for greenhouse frames and irrigation.
  • Industrial Plumbing: Corrosion-free water and chemical transport.

Certifications & Compliance

  • ISO 1461 (Hot-Dip Galvanizing)
  • ASTM A53/A500 (Structural Integrity)
  • NSF 61 (Potable Water Safety)
  • UL Listed / FM Approved (Fire Safety)
