    Surface Aspects

     

    Surface quality

    Surface quality complies with standard: EN 10346:2015. Galvanised steels are available in surface quality A, B or C (MagiZinc® in surface quality A or B). 

    For the highest surface quality requirements we also offer Serica®.

    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 quality 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.

    Overview

    Overview

     

    You can choose from a range of metallic coatings including Tata Steel’s innovative MagiZinc® coating. MagiZinc delivers improved corrosion resistance with up to half the thickness of a conventional zinc coating. The thinner, lighter coating means increased yield per tonne of steel.

    The main benefits of our metallic coated steel include:

    • consistent and reliable end-product quality
    • proven corrosion resistance for extended product life

    Metallic coated grades include advanced high-strength steels, high-strength steels, structural steels and grades for forming.

    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.

    MagiZinc

    MagiZinc steel (+ZM) is coated with a zinc coating containing
    additional magnesium and aluminium.

    Surface aspects

    Surface Aspects

     

    Surface quality

    Surface quality complies with standard: EN 10346:2015. Galvanised steels are available in surface quality A, B or C (MagiZinc® in surface quality A or B). 

    For the highest surface quality requirements we also offer Serica®.

    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 quality 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 finish

    This surface treatment temporarily protects the zinc-coated material against white rust during transportation and storage (not applicable to all qualities – 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 – please contact us for details).

    Chromate passivation*

    Tata Steel in the UK currently offers a chromate passivation treatment.

    This will be withdrawn in the near future (due to REACH legislation) and customers are strongly advised to consider an alternative surface treatment.

    Untreated (U)

    Please contact us regarding the availability of untreated coils.

    * Passivated material can be supplied with a maximum width of 1550mm. Wider passivated material
