Cold-rolled
Structural steel

Our cold-rolled structural steel is suitable for a wide range of applications.

It has a guaranteed minimum strength and offers good weldability for ease of processing.

Applications

  • Domestic appliances
  • Furniture
  • Tubing
  • Racking and shelving
  • Pressure vessels

Surface aspects

Surface quality

 

Surface quality A

Defects that do not influence the formability or the application of surface coatings are permitted. They are defects such as pores, minor scratches, slight indentations, small grooves or slight discolouration. 

Surface quality B

The better side must be free of defects that can spoil the uniform appearance of a high-quality paint or of an electrolytic coating. The other side must at least conform to surface quality A. Not all combinations of thickness and width are available in surface quality B. Please contact us for details. 

Inspected side

As a rule, the upper side of the strip is inspected; on request, the strip can be wound so that the inspected side is the underside.

 

Surface texture/roughness

Cold-rolled annealed and skin-passed steel is available in several surface textures. Unless specified otherwise, Tata Steel will supply normal roughness. The table below shows the range of surface textures according to EN 10130:2006.

Preservative oil

The standard oil applied by Tata Steel acts as a protective coating. Other types of oil may be available to meet your requirement.
Tata Steel offers a range of oiling levels from 0.25 - 1.7 g/m2 per side.
Other oiling levels are available on request. Tata Steel is not responsible for the risk of corrosion during storage or shipment if material is ordered in the un-oiled condition.

 

Surface cleanliness

Tata Steel can guarantee improved surface cleanliness on request for batch-annealed products. The cleanliness is tested with a tape test, in which the loss of reflection is measured. The reflection gives an indication of the oil residue on the annealed product. Two levels of loss of reflectivity are available for batch annealed products: a maximum of 20% or a maximum of 30%. Continuously-annealed products typically exhibit a loss of reflection up to around 10%.

Out-of-squareness (products supplied as cut sheets only)

The deviation does not exceed 1% of the actual width of the sheet according to the EN 10131: 2006 standard. The deviation from the edge camber does not exceed 5mm for a length of 2 metres as specified in EN 10131: 2006.

 

Flatness (products supplied as skin-passed cut sheets only)

Flatness complies with EN 10131: 2006
If there is a dispute about the flatness of material that was ordered to the special tolerances shown in table 8 of EN 10131: 2006, then the minimum acceptable standards of flatness described below must be verified.

Coil welds

For batch-annealed coils, in general, pickling line welds are included. The number of permissible recoiling line welds is determined in consultation with the customer. If welds are permitted, Tata Steel is better able to implement the best coil weight. A recoiling line weld is marked with a single hole in the centre of the strip, close to the weld. On request the identifying hole can be left out. Coils with welds are available on continuously-annealed products – please contact us for details. You can find details on how to get in touch with us in 'Contact Us' below.

Out-of-squareness (products supplied as cut sheets only)

The deviation does not exceed 1% of the actual width of the sheet according to the EN 10131: 2006 standard. The deviation from the edge camber does not exceed 5mm for a length of 2 metres as specified in EN 10131: 2006.

 

Flatness (products supplied as skin-passed cut sheets only)

Flatness complies with EN 10131: 2006
If there is a dispute about the flatness of material that was ordered to the special tolerances shown in table 8 of EN 10131: 2006, then the minimum acceptable standards of flatness described below must be verified.

Winding

For winding, there may be a maximum width gap of 3mm between two con­se­cutive windings. The total width stagger across the coil wall will not exceed 10mm.

 

Dimensions and coil weights

Tata Steel can supply cold-rolled steel with the following minimum and maximum dimensions and coil weights.

Description Availability
Coil diameter inner 610mm
(508mm available on request)
Coil diameter outer 10/7 x width max
1000mm min.
2800mm max.
Coil weight 30 t max.
30 - 45 t max available after consultation
Coil weight limited by maximum outer diameter
Maximum weight allowed by road/rail transport
Some products may have different coil weight ranges available
Usually a minimum coil weight up to 85% of the maximum coil weight can be requested
KIM: width ≤ 1200mm 11.9 - 21.5 kg/mm width
KIM: 1200mm < width ≤ 1700mm 11.9 - 21 kg/mm width
KIM: width > 1700mm 10.3 kg/mm width and 11.9 - 21 kg/mm width
Minimum tonnage per order Refer to price list for order quantity details
Minimum order quantities may apply

 

 

Coil welds

For batch-annealed coils, in general, pickling line welds are included. The number of permissible recoiling line welds is determined in consultation with the customer. If welds are permitted, Tata Steel is better able to implement the best coil weight. A recoiling line weld is marked with a single hole in the centre of the strip, close to the weld. On request the identifying hole can be left out. Coils with welds are available on continuously-annealed products – please contact us for details. You can find details on how to get in touch with us in 'Contact Us' below.
