Special lengths: on request
The "unchromed length" of each bar( the distance at each end over which the chrome-layer properties and tolerances can not be guaranteed) is at most 0.15 m per end, maximum 0.3 m in total per bar. Fixed or cut lengths can be supplied on request.
Surface roughness: Ra - max. 0,20 µm (normally in the range 0,10-0,15 μm)
Chrome thickness:
- min. 15 µm for dia ≤ 20 mm
- min. 20 µm for dia > 20 mm
Chrome micro hardness: min. 950 HV0.1
Straightness:
- Ø ≤ 16mm = max 0.3mm/meter
- Ø > 16mm = max 0.2mm/meter
From Ø 6 to 100 mm (Imperial range: 1/4"-4")

Packaging
NIMAX CBX bars can be supplied with three packaging options:
- For diameter between16-100 mm individually cardboard tubes with caracteristic red and white spiral stripes
- For diameter between 16-80 mm bundles with max 1000kg weight and for diameter ≥ 80 mm bundles with maximum 1500 kg weight
- For dia < 16 mm plastic spacer rings in wooden boxes with maximum 900 kg weight
Each bundle with weight ≤ 1200 kg being equipped with two thongs (four for more than 1200 kg).
On wooden euro-palets from smallest cut lenghts.
Marking
For each bar the cardboard tube will be marked with black colour: "NIMAX CBX / diameter/ Tolerance / Steel grade/ heat no. / date".
On each bundle, wooden case or palet they will be applied minimum one label for identification.
