Source DX51D+Z hot-dip galvanized steel sheet for roll forming, ducts, metalwork and coated sheet fabrication. Share your gauge, zinc coating, sheet size and quantity for a quotation matched to your purchase list.
Build your RFQ around the exact coating mass, thickness, finish and cut dimensions your production requires.
| Purchase item | Reference / requirement |
|---|---|
| Grade | DX51D+Z — hot-dip zinc-coated forming grade |
| Reference standard | EN 10346:2026; specify the contract edition for your order |
| Dimensional tolerance | EN 10143, normal or special tolerance as agreed |
| Coating | Zinc (Z); define the coating mass, e.g. Z100, Z140, Z200, Z275 |

| Surface / treatment | Spangle finish, surface quality, skin pass, passivation or oiling as required |
| Inspection | MTC, coating mass checks, dimensional checks as agreed |
| Delivery | Quantity, packing method, destination and shipment schedule |
Send one material schedule with each item below.
The dimensions above are example RFQ formats. Current production, cut length and stock availability are confirmed against your exact specification.
The +Z suffix specifies a hot-dip zinc coating. Your Z designation defines the coating mass for procurement and inspection.
| Coating code | Minimum total mass — both faces | Typical zinc thickness / face |
|---|---|---|
| Z100 | 100 g/m² | ≈ 7 μm |
| Z140 | 140 g/m² | ≈ 10 μm |
| Z180 | 180 g/m² | ≈ 13 μm |
| Z200 | 200 g/m² | ≈ 14 μm |
| Z225 | 225 g/m² | ≈ 16 μm |
| Z275 | 275 g/m² | ≈ 20 μm |
| Z350 | 350 g/m² | ≈ 25 μm |
