EN-Product-Hot-rolled-All grades Shape and dimensional tolerances TSUK

Shape and dimensional tolerances

Shape and dimensional tolerances

The specified values for wide strip do not apply to the uncropped ends of the coil (‘head’ and ‘tail’). The length of these uncropped ends is calculated using the following formula:

length (in metres) = 90/nominal thickness (in mm), with a maximum of 20 metres.

If required, this part of the coil can be removed, however an additional cost may be charged for this.

 

Tolerances on thickness

Tata Steel can supply to full thickness tolerance specified in EN 10051:2010.

Tighter tolerances are available as shown below:
