Product Introduction

‌DX51D Z150 Galvanized Steel Sheet: High-Performance Corrosion Resistance for Industrial Applications‌


‌DX51D Z150 Galvanized Sheet Product Overview‌

DX51D Z150 galvanized steel sheet is a cold-rolled carbon steel product with a ‌150g/m² zinc coating‌ applied via the hot-dip galvanizing (HDG) process. Compliant with ‌EN 10346 standards‌, this material combines ‌excellent formability‌ (suitable for deep drawing/bending) with ‌enhanced rust protection‌, delivering 8-15 years of maintenance-free service in moderate environments. Its zinc-iron alloy layer provides superior adhesion compared to electrogalvanized alternatives, making it ideal for automotive panels, roofing systems, and agricultural equipment.


‌Key Technical Specifications‌

‌1. Base Material Properties‌

Parameter DX51D Z150 Values Testing Standard
Thickness Range 0.12mm – 6.00mm (±0.02mm) ISO 9444
Yield Strength 240-380 MPa ISO 6892-1
Tensile Strength 270-500 MPa ISO 6892-1
Elongation (A80) ≥22% ISO 7438
Zinc Coating Z150 (150g/m²) ISO 1461

Note: Z150 coating equals 210μm zinc thickness

‌2. Chemical Composition‌

Element C Si Mn P S Ti
Content ≤0.12% ≤0.50% ≤0.60% ≤0.100% ≤0.045% ≤0.30%

This low-carbon formulation ensures optimal ‌weldability‌ (C.E. <0.35) and ‌cold-forming capabilities‌ without cracking.


‌Performance Advantages‌

  1. ‌Superior Corrosion Protection‌
    • Salt spray resistance: ‌480-720 hours‌ (ISO 9227)
    • Zinc-iron alloy layer hardness: ‌250 HV‌ (vs 150 HV for pure zinc)
  2. ‌Surface Treatment Options‌
    Code Treatment Key Benefit
    C Chromate passivation 72hr extra rust prevention
    Q Phosphating + oiling Class 1 paint adhesion (ISO 2409)
    O Oiling only Scratch resistance during transport
  3. ‌Environmental Adaptability‌
    Application Environment Recommended Coating Service Life*
    Indoor dry storage Z150 + Chromate (C) 15-18 years
    Coastal regions Z150 + PVDF topcoat 12-15 years
    Automotive underbody Z150 + Epoxy primer 10+ years

Based on ISO 12944-2 corrosion categories


‌Comparative Analysis‌

‌DX51D vs Competing Grades‌

Grade Coating Weight Formability (r-value) Cost per Ton
DX51D Z150 150g/m² 1.8 $980
SGCC (JIS) 120g/m² 1.5 $850
ASTM A653 G90 (275g/m²) 1.2 $1,150

Key advantage: DX51D Z150 offers 25% better deep-drawing performance than SGCC grades


‌Manufacturing & Quality Control‌

  • ‌Production Process‌:
    1. Continuous annealing at 720°C
    2. Zinc bath immersion (455°C ±5°C)
    3. Air knife coating control (±5g/m² precision)
  • ‌Certifications‌:
    • ISO 9001:2015 quality management
    • RoHS compliance (Pb/Cd-free)
  • ‌Testing Protocols‌:
    • 3T bend test (ASTM A90)
    • XRF coating thickness verification

‌Recommended Applications‌

  1. ‌Construction Sector
    • Standing seam roofs (0.6mm sheets withstand 150km/h winds)
    • HVAC ducting (meets SMACNA airflow standards)
  2. ‌Automotive Manufacturing
    • Body panels (compatible with MIG/TIG welding)
    • Chassis components (salt spray resistance >600hrs)
  3. ‌Agricultural Equipment
    • Grain silos (Z150 + Q treatment resists fertilizer corrosion)
    • Livestock enclosures (self-healing zinc protection)

‌Why Choose DX51D Z150?‌

  • ‌Custom Sizing‌: Available in 600-1500mm widths with CNC cutting services
  • ‌Global Compliance‌: Meets EN 10346 (EU), JIS G3302 (JP), GB/T 2518 (CN)
  • ‌Sustainable Choice‌: 85% recycled steel content with zinc recovery system
