Packaging
NIMAX 1000 bars can be supplied with two packaging options:
- For diameter between 3/4" - 8" in bundles with individually cardboard tubes with caracteristic red and white spiral stripes
- For diameter between 3/4" - 3" bundles with max 2205 pounds weight and for diameter ≥ 3" in bundles with maximum 3307 pounds weight
Each bundle with weight ≤ 2645 pounds being equipped with two thongs (four for more than 2645 pounds).
On wooden euro-palets from smallest cut lenghts.
Marking
For each bar the cardboard tube will be marked with black colour: "NIMAX CODE / Diameter / Tolerance / Steel grade/ Heat no. / Date".
On each bundle (or wooden boxe / palet) they will be applied minim one label for identification.
