Technical Data
EN 10346 DX51D+Z Galvanized Steel Roofing Sheet Chemical Composition
| Element | Carbon (C) | Manganese (Mn) | Phosphorus (P) | Sulfur (S) | Silicon (Si) | Aluminium (Al) | Others |
| Content (wt%) | ≤ 0.12 | ≤ 0.60 | ≤ 0.045 | ≤ 0.045 | ≤ 0.03–0.15 | 0.015–0.06 | Balance Fe |
Notes:
DX51D+Z is a low-carbon steel with good formability and suitable for hot-dip galvanizing.
Coating with Zinc (Z) has excellent corrosion resistance.
The composition may vary slightly from producer to producer or rolling according to process, but the above values are the standard range.
EN 10346 DX51D+Z Galvanized Steel Roofing Sheet Mechanical Property
| Property | Typical Value |
| Yield Strength (ReH) | 140–280 MPa (depends on thickness) |
| Tensile Strength (Rm) | 270–410 MPa |
| Elongation (A50) | 23–34% |
| Hardness (HB) | ~120 HB (varies with cold-rolled thickness) |
| Bend Test | 180° bend over sheet thickness without cracking (depends on thickness) |
| Zinc Coating (Z) | Z60 – Z275 g/m² per side (depending on corrosion requirement) |
Notes
Thickness: Normal roofing thicknesses range from 0.4 mm to 1.0 mm.
Coating: Z60–Z275 offers light to heavy corrosion protection; higher values are applied in aggressive environments.
Formability: DX51D+Z can be roll-formed, bent or cut with ease, which make it a perfect material for roof profiles.
Grades For Roofing: We usually use DX51D+Z100 or Z120 for the normal roofing in good balance between cost and corrosion protection.
EN 10346 DX51D+Z Galvanized Steel Roofing Sheet Sizes
| Parameter | Typical Range | Notes |
| Thickness (t) | 0.35 – 1.2 mm | Most roofing sheets are 0.4–0.7 mm; thicker sheets used for industrial roofs. |
| Coating (Z) | Z60 – Z275 g/m² per side | Determines corrosion resistance; Z120–Z180 common for roofing. |
| Width (B) | 600 – 1250 mm (mill finish) | Roll-formed widths vary with profile; effective cover width is slightly less. |
| Length (L) | 2 – 12 m | Can be cut to customer requirements; long sheets reduce joints. |
| Spangle (Zinc coating appearance) | Regular / Minimized / Zero | Depends on aesthetic requirements. |
| Weight | 3–10 kg/m² | Depends on thickness and coating. |

1.What is EN 10346 DX51D+Z steel?
EN 10346 DX51D+Z is a cold rolling low carbon steel sheet with zinc coating (galvanized) used for rust prevention.
DX51D: Cold rolled steel good for forming and bending.
+Z: Hot-dip zinc coated for resilience.
Application: roofing, cladding, gutter, light industrial buildings.
2.The Advantage
Corrosion Resistant: The zinc coating prevent steel from rusting.
Light & Buildable - Can be roll-formed, bent and cut.
Long Life: Minimal Maintenance Over A Long Life.
Affordable: A budget-friendly options for the residential, commercial and industrial roofs.
3.Service Life
Normal surroundings: 15–25 years.
Z180–Z275 or pre-painted sheets are recommmended in coastal or industrial areas.
4.Painting / Coating Options
It can be pre painted (PPGI) with polyester, PVDF or other paints to enhance the appearance and provide additional protection against corrosion.
5.Industrial Applications
Ideal for medium-duty general purpose roofing.
Severe heavy-duty loads may necessitate the use of thicker sheets, or structural steel (i.e. ASTM A653 G60).
6.Maintenance Tips
Clean roof from debris, leaves and dust.
Do not scratches your skin off steel.
