RangePeeled / Ground: 27 - 160 mm
Dimensional tolerancesPeeled: H11 or, upon request, H10 or H9 Ground: Rough grinding IT 9, fine grinding IT 8, 7 or 6 , upon request
Surface FinishesPeeled: Ra < 1.0 μmGround: Ra < 0.8 μm (rough grinding), Ra < 0.4 μm (fine grinding)
OvalizationPeeled / Ground: Max 50% of the diameter tolerance range, measure as diameter difference
StraightnessPeeled: From 0.5 to 2 mm/mGround: 0,5 mm/m
Bar LengthPeeled / Ground: Optional in the 3 – 12 m range. Tolerance on length is +100/-0 mm. A tighter tolerance on length can be obtained by means of an additional cut.
BevellingPeeled / Ground: Applicable on bars with a diameter ≤ 120 mm, on one or both ends with 30, 45 or 60° angles. Bevel depth can be between 1 and 5 mm, according to request.

We are able to offer cold processed materials in any of the wide range of steel grades produced by ABS.
Qualisteel cold-rolled bars are characterized by tight tolerances and excellent surface finishes thanks to a rational and modern production line.
We double-check our products inline, that is before and after peeling, so as to guarantee zero surface defects.
