Steel for forming
Our cold-rolled forming steels are available in a wide range of grades and corrosion-resistant coatings. Each grade is designed for specific applications and comes with a choice of surface quality. Extensive dimensional choice provides opportunities for cutting waste and maximizing yield.
MagiZinc® improves corrosion resistance with half the thickness of conventional zinc coatings, increasing yield, reducing cost and facilitating stronger, lighter products. It offers improved automotive corrosion protection and higher process efficiency.

Surface Aspects
Surface quality
Surface quality complies with ASTM standards A653: 2008 and A924: 2009. The products can be delivered with the following coating/surface types:
Minimized spangle (standard 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.
Minimized spangle temper rolled (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.
Extra smooth (best surface, exposed)
Surface quality 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. As a rule, the upper side of the strip is inspected; on request the strip can be turned over so that the underside is the inspected side.
MagiZinc® is currently only available with standard or improved surface qualities.
Surface roughness
Metallic coated steel will normally be supplied with a regular matte finish:
| Description | Roughness µinch CLA |
|---|---|
| regular matte | 30 - 61 |
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 may be available to meet your requirement – please contact us.
Tata Steel offers the following range of oiling levels for all coating types:
Lightly oiled: 55 mg/ft2 per side
Regular oiled: 110 mg/ft2 per side
Other oiling levels are available on request. If no amount is indicated in your specification, a regular amount of oil will be applied.
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 – please consult us).
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 consult us).
Please contact us on the availability of other surface treatments.

Surface Aspects
Surface quality
Surface quality complies with ASTM standards A653: 2008 and A924: 2009. The products can be delivered with the following coating/surface types:
Minimized spangle (standard 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.
Minimized spangle temper rolled (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.
Extra smooth (best surface, exposed)
Surface quality 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. As a rule, the upper side of the strip is inspected; on request the strip can be turned over so that the underside is the inspected side.
MagiZinc® is currently only available with standard or improved surface qualities.
Surface roughness
Metallic coated steel will normally be supplied with a regular matte finish:
| Description | Roughness µinch CLA |
|---|---|
| regular matte | 30 - 61 |
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 may be available to meet your requirement – please contact us.
Tata Steel offers the following range of oiling levels for all coating types:
Lightly oiled: 55 mg/ft2 per side
Regular oiled: 110 mg/ft2 per side
Other oiling levels are available on request. If no amount is indicated in your specification, a regular amount of oil will be applied.
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 – please consult us).
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 consult us).
Please contact us on the availability of other surface treatments.
