Hardness 250–550 MPa tensile strength (grade-dependent)
Length 6–12 meters (standard), cut-to-size or coiled options
Applications Construction, HVAC, automotive, water/gas pipelines, agricultural infrastructure

Technical Properties

Tensile & Bend Strength

  • Tensile Strength: Ranges from 270–500 MPa for low-carbon grades (e.g., DX51D) to 390–630 MPa for structural grades (e.g., S550GD).
  • Bend Strength: Achieves ≤3T/4T (top/back) due to uniform zinc adhesion, suitable for cold-forming applications like roofing and automotive parts.

Weight Calculation

Weight (kg/m) = (OD – WT) × WT × 0.02466
Example: For a 50mm OD pipe with 2mm wall thickness:
(50 – 2) × 2 × 0.02466 = 2.37 kg/m. Custom calculators provided for galvanized steel pipe for sale.

 

Identification Marking

  • Laser-etched labels include:
    • Grade (e.g., DX51D+Z, SGCC).
    • Zinc coating (e.g., Z275).
    • Mill origin and production date.
  • Compliant with ASTM A653 and EN 10346 standards.

Why Stainless Steel Corrodes?

While hot-dip galvanized pipe fittings resist rust through zinc’s sacrificial protection, stainless steel may corrode due to:

  1. Chloride Exposure: Coastal environments or de-icing salts induce pitting.
  2. Mechanical Damage: Scratches or welding defects expose the base metal to oxidation.
  3. Galvanic Corrosion: Contact with dissimilar metals (e.g., copper) accelerates degradation.
  4. Temperature Extremes: Prolonged high heat (＞300°C) destabilizes passive oxide layers.

Manufacturing Process

Stage Description
Material Prep Cold-rolled steel coils cleaned via pickling to remove oxides.
Galvanizing Dipped in molten zinc (435–455°C) to form Fe-Zn alloy layers (Z275 coating).
Surface Treatment Chromated or oiled for enhanced corrosion resistance.
QC Inspection Eddy current testing, salt-spray checks (＞1,000 hours), and coating thickness verification.
