Dimensions
Our bright steel portfolio contains more than
5,000 items in some 400 material variations in
drawn, peeled and ground finishes.
The dimensional ranges of our bright steels
are:
drawn – between 4.5 mm and 80 mm round
turned – between 14 mm and 150 mm round
ground – between 4 mm and 125 mm round
squares, hexagons and octagons up to 80 mm
Dimensional limits are material dependent.
Key steel is available as per DIN 6880,
sharp-edged or with bevelled edges.
Special sections are supplied according to
drawings or samples.
Dimensions smaller than 22 mm also come
as spooled coils.
Product lengths are either according to DIN
provisions or as customary in the trade.
Special fixed and short lengths as well as special
edge finishes are supplied on request.
Admissible deviations from the nominal
dimension as per DIN/ISO tolerances common
for bright steel.
All tolerances up to tolerance class IT6 can be
supplied on request.
Special sections and flat steels can be supplied
on request in all finishes according to drawing or
sample.

The above tolerances are negative deviations from the nominal dimension. For example, a nominal diameter of 20 mm with
tolerance class h9 has a tolerance range of -0.052/+0 giving an acceptable product size range of 19.948 mm to 20.000 mm.
