Product Introduction

‌DX52D Galvanized Pipe: High-Performance Corrosion-Resistant Steel for Multisector Applications‌.

‌Engineered for Longevity: Construction, Automotive & Industrial Systems‌

DX52D galvanized pipe is a ‌cold-rolled steel pipe‌ with a zinc coating (Z275 grade, 20–25 µm) offering 5–8x longer lifespan than non-galvanized alternatives. Ideal for harsh environments, its ‌dual-phase microstructure‌ ensures tensile strength up to 540 MPa while resisting corrosion in applications like roofing, automotive underbodies, and agricultural equipment.


‌Certifications & Key Advantages‌

  • ‌EN 10346 & ASTM A653 Certified‌: Compliant with JIS G3302 and GB/T 2518 standards.
  • ‌Cost Efficiency‌: 45% lower lifecycle costs vs. stainless steel (30-year service life).
  • ‌Custom Sizing‌: Thickness 0.1–300 mm (±0.15 mm), width up to 3 meters.
  • ‌MOQ 1 Ton‌: Available in hot-dip galvanized (HDG) or electroplated (EG) finishes.

‌Technical Specifications‌

‌Mechanical Properties‌

Property Value Test Standard
Yield Strength ≥260 MPa ISO 6892-1
Tensile Strength 340–540 MPa ASTM E8/E8M
Elongation (A80) ≥18% EN ISO 6892-2
Zinc Coating 180–275 g/m² (HDG) EN 1461

‌Coating Details‌:

  • ‌Hot-Dip Galvanizing (HDG)‌: 50–85 µm layer (Z275/Z450 grades).
  • ‌Electroplating (EG)‌: 5–25 µm coating for indoor/low-humidity use.
  • ‌Surface Prep‌: ISO 8501-1 Sa2.5 blast cleaning (25–75 µm profile).

‌Dimensional Tolerances‌

Parameter Tolerance
Thickness ±0.15 mm
Width ±5 mm
Length ±10 mm

‌Applications‌

  1. ‌Construction‌: Anti-corrosion roof panels, HVAC ducts, and structural gratings.
  2. ‌Automotive‌: Exhaust systems, chassis components, and fuel tanks.
  3. ‌Agriculture‌: Grain silos, irrigation pipes, and livestock equipment.
  4. ‌Energy‌: Oil well casings, offshore platform supports, and solar mounting systems.

‌Fabrication Guidelines‌

  • ‌Cutting‌: Laser/plasma (pre-heat >120°C for HDG).
  • ‌Welding‌: Use ER70S-6 electrodes (preheat 100–150°C).
  • ‌Bending‌: Minimum radius = 2.5x pipe diameter.
  • ‌Painting‌: Apply epoxy primer (5 µm) + polyester topcoat (20 µm).

‌Quality Assurance‌

  • ‌Coating Adhesion‌: ISO 2409 cross-cut test (Class 0 rating).
  • ‌Salt Spray Test‌: 1,200+ hours (ASTM B117) for HDG pipes.
  • ‌Certifications‌: Mill Test Reports (EN 10204 3.2), RoHS, and REACH.

‌Competitive Edge‌

  • ‌Lifespan‌: 30–50 years in coastal/industrial zones.
  • ‌Lead Time‌: 10–20 days (MOQ 1 ton).
  • ‌Sustainability‌: 100% recyclable with 30% lower CO₂ emissions than aluminum.

‌Logistics & Compliance‌

  • ‌Packaging‌: VCI-coated paper + steel straps (ISPM15 compliant).
  • ‌Temperature Range‌: -40°C to 300°C (HDG), 0°C to 200°C (EG).
  • ‌Optional Coatings‌: Aluminized (ALUZINC) or PVC-laminated upon request.

‌Comparative Analysis‌
