EN-Engineering-Product-Metallic coated-All Grades Coatings Surface aspects
Coatings
Three types of metallic coating are available:
Pure zinc
Galvanised steel (+Z) is coated with an almost pure zinc coating (>99% zinc).
Zinc-iron alloy
Galvannealed steel (+ZF) is coated with a zinc coating containing approximately 8-12% iron.
For further information on our galvannealed products please visit our Automotive catalogue.
MagiZinc
MagiZinc steel (+ZM) is coated with a zinc coating containing additional magnesium and aluminium.
Coating weight
| Coating | Minimum | Maximum |
|---|---|---|
| Pure zinc (Z) | 90 (6 µm/side) | 600 (42 µm/side) |
| Zinc-iron (ZF) | 90 (6 µm/side) | 140 (10 µm/side) |
| MagiZinc (ZM)1 | 70 (5 µm/side) | 310 (22 µm/side) |
Coating weight measured in g/m2 double-sided (µm, per side).
Coils with coatings > 450 g/m2 will be supplied in oscillated coiled condition.
Coils coated with 600 g/m2 are only available in width range 980 to 1300 mm.
1 For MagiZinc (ZM) coating weights below 100 g/m2 please visit our Automotive catalogue.
Surface quality
Surface quality complies with standard: EN 10346:2015. Galvanised steels are available in surface quality A, B or C.
For the highest surface quality requirements we also offer Serica FLO®. For more details please visit our Automotive catalogue.
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
For more information on surface quality C please visit our Automotive catalogue.
Surface finish

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) |
0.25 - 1.5 g/m2 |
|
Zinc-iron (ZF) |
0.5 - 1.5 g/m2 |
|
MagiZinc® (ZM) |
0.25 - 1.5 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).
Untreated (U)
Please contact us regarding the availability of untreated coils.

Properties
Mechanical properties
Metallic coated high-strength steel grades have the following mechanical properties (skin-passed) - these are measured transverse to the rolling direction:
Micro-alloyed steels

| Min. n-value | - | |
Not in EN 10346:2015. Tata Steel’s own specification.
Lower yield strength or 0.2% proof stress applies.
BH2 refers to the increase of 0.2% proof stress after heating (bake hardening). Not applicable for hot rolled substrate.
For galvannealed grades (ZF) the minimum elongation before fracture is lowered by 2%.
For galvannealed grades (ZF) the minimum r90-value is lowered by 0.2.
