FAQ:
  • What are the common applications of DX51D galvanized sheets?
    DX51D galvanized sheets are widely used in construction, automotive, home appliances, and manufacturing of mechanical parts, toys, and decorations due to their durability and corrosion resistance.
  • What is the difference between hot galvanizing and pre-galvanizing?
    Hot galvanizing involves dipping the steel sheet in molten zinc, providing a thicker coating (60-275g/m²), while pre-galvanizing applies a thinner zinc layer (80-275g/m²) before fabrication, offering a smoother finish.
  • How does the zinc coating thickness vary based on the environment?
    For indoor use, Z10 or Z12 (100-120g/m²) is sufficient. Suburban areas require Z20 (200g/m²), urban/industrial areas need Z27 (270g/m²), and coastal areas require thicker coatings to prevent corrosion.
