EN-Product-Metallic coated-All Grades Coatings Surface aspectsTSUK
Coatings
Three types of metallic coating are available:
Pure zinc
Galvanised steel (Z/GI) is coated with an almost pure zinc coating (>99% zinc).
Zinc-iron alloy
Produced in the Netherlands. For further information click here.
MagiZinc
MagiZinc steel (ZM) is coated with a zinc coating containing additional magnesium and aluminium.
Coating weight
| Coating | Minimum | Maximum |
|---|---|---|
| Pure zinc (Z/GI) | 90 (6 µm/side) | 275 (20 µm/side) |
| MagiZinc (ZM)1 | 70 (5 µm/side) | 310 (22 µm/side) |
Coating weight measured in g/m2 double-sided (µm, per side).
Surface quality
Surface quality complies with standard: EN 10346:2015. Galvanised steels are available in surface quality A, B or C.
Also, Serica FLO® surface quality produced in the Netherlands. For further information click here.
Surface quality A: as coated surface
Imperfections such as pimples, marks, scratches, pits, variations in surface appearance, dark spots, stripe marks and light passivation stains are permissible.
Stretch levelling breaks or run-off marks may appear. Coil breaks and stretcher strains may also appear.
Surface quality B: improved surface
With this surface quality, small imperfections such as stretch levelling breaks, skin pass marks, slight scratches, indentations, surface structure, zinc run-off marks and light passivation stains are permissible.
Surface quality C: best quality surface
Surface condition C is obtained by skin passing. The controlled surface for the exposed side enables application of a uniform paint finish. The reverse surface has, at least, the characteristics of surface quality B.
Surface finish
Pure zinc
MA: minimised spangle, as coated surface (Z/GI).
MB: minimised spangle, improved surface (Z/GI).
MC: minimised spangle, best quality surface (Z/GI).
MagiZinc®
A : as coated surface (ZM).
B : improved surface (ZM).
C: best quality surface (ZM).
Surface roughness
Metallic coated steel (with the exception of galvanised steel with standard surface (MA) can be supplied in various grades of roughness – please contact us for more details. If no roughness is specified, roughness will be as shown in the table below.
Roughness Ra (µm) |
|
|---|---|
cut off 0.8mm | cut off 2.5mm |
| 0.6 - 1.9 | 0.7 - 2.2 |
Surface treatments
The surface treatments available are O, C and CO.
Oiling (O)
The material surface can be oiled with preservative oil. Other types of oil - for increasing strength or reducing weight – are available to help achieve your optimum performance parameters. Please contact us for details.
Tata Steel offers the following range of oiling levels:
| Coating type | Capability |
|---|---|
| Pure zinc (Z/GI) | 0.5 - 1.6 g/m2 |
| MagiZinc® (ZM) | 0.5 - 1.6 g/m2 |
Other oiling levels are available on request.
Chromium-free passivation (C)
This surface treatment temporarily protects the zinc-coated material against white rust during transportation and storage (not applicable to all qualities and dimensions – please contact us for details).
Chromium-free passivation and oiled (CO)
Please request this combination of surface treatments if you require extra protection against white rust formation (not applicable to all qualities and dimensions – please contact us for details).
T-treatment
Please contact us for further information.
Prime Lubrication Treatment (PLT)
Prime Lubrication Treatment facilitates the manufacturing of stamped components by minimising known issues in stamping and joining.
Currently Under development, please contact us regarding further information
Untreated (U)
Please contact us regarding the availability of untreated coils.

Properties
Mechanical properties
Metallic coated steel for forming has the following mechanical properties. These are measured transverse to the rolling direction:
| EN 10346: 2015 | Grade | DX52D+Z/+ZM |
|---|---|---|
| Yield strength 1 Re | N/mm² | 140 - 300 3 |
| Tensile strength Rm | N/mm² | 270 - 420 |
| Elongation 2 | % | 26 |
| Min. r-value | - | |
| Min. n-value | - |
1. If the yield point is not pronounced, the values apply to the 0.2% - proof strength Rp0.2 ; if the yield strength is pronounced, the values apply to the lower yield point ReL.
2. Decreased minimum elongation values apply for product thickness t ≤ 0.50 mm (minus 4 units) and for 0.50 mm ≤ t ≤ 0.70 mm (minus 2 units).
Elongation after fracture A uses test piece length L0 = 80 mm.
3. This value applies to skin-passed products only (surface qualities B and C).
Chemical composition
Tata Steel complies with the following cast analysis:
