EN-Engineering-Product-Metallic coated-All Grades Coatings Surface aspectsTSE

Coatings and 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

CoatingMinimumMaximum
Pure zinc (Z)90 (6 µm/side)600 (42 µm/side)
Zinc-iron (ZF)90 (6 µm/side)140 (10 µm/side)
MagiZinc (ZM)170 (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.
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

Surface condition C is obtained by skin passing. The controlled surface shall make it possible to apply a uniform high-class paint finish. The other surface shall at least have the characteristics of surface quality B.

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.

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 typeCapability
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.

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.

For further information please visit our Prime Lubrication Treatment (PLT) page.
