What is DX54D+Z galvanized steel coil equivalent to?
DX54D+Z is a high-quality deep-drawn galvanized steel sheet in accordance with European standards (EN 10346), with excellent formability (elongation ≥34%, r value ≥1.8) and anti-corrosion coating (Z100-Z275).
Equivalent to:
China GB: DC54D+Z (GB/T 2518), with completely corresponding performance parameters;
Japan JIS: SGCD54+Z (KS D 3506), with equivalent stamping grades;
US ASTM: A653 DDS Type B (coating G90), please note that the North American standard focuses on coating rather than stamping grading;
German standard DIN: directly adopt DX54D+Z (EN10346 original standard).

If the product requires complex molding (such as car door panels, fuel tanks), DX54D+Z is preferred.
How to choose the thickness of the zinc coating for DX54D+Z?
The galvanized layer is classified by grams per square meter (g/m²), common specifications:
Z100: 100g/m² (≈7μm) on one side, suitable for general anti-corrosion needs (such as home appliances).
Z140: 140g/m² (≈10μm) on one side, suitable for higher anti-corrosion requirements (such as automotive parts).
Z275: 275g/m² (≈20μm) on one side, suitable for harsh environments (such as building exterior panels).
Selection suggestions:
Ordinary environment (such as indoors) → Z100
Wet/industrial environment → Z140/Z275
Ultra-high corrosion resistance requirements → Alloyed galvanizing (DX54D+ZA)
What is the steel material of DX54D+Z steel coil?
DX54D+Z is the galvanized steel plate grade in the European standard (EN 10346), with a yield strength of 140-300 (MPa) and a tensile strength of 270-420 (MPa).
DX54D: indicates the steel grade, with high deep drawing performance (higher than DX53D, close to DC04 level).
+Z: indicates hot-dip galvanizing (Zinc Coating), common coatings such as Z100 (single-sided 100g/m²), Z140, Z275
What surface treatments are available for DX54D+Z steel?
In addition to standard galvanizing (Z), the following treatments are available:
ZF: Chromium-free passivation (environmentally friendly, improves corrosion resistance).
ZM: Oiling (short-term rust prevention, suitable for storage and transportation).
ZA: Galvannealed (the coating contains iron, has better corrosion resistance, and is suitable for painting).
