Corner radius
The edge is produced with a radius of 1 or 1,5 mm. with a tolerance of +/- 0,3 mm. Other radius can be produced according to customer request.

Oscillated coils

The coils are placed on wooden pallets following customer requirements.
For other options please consult.


In order to protect the material during transportation, different kinds of packaging are used to guarantee delivery in perfect condition.

Overseas packaging

The bundles are oiled and covered with corrosion inhibiting paper (VCI); this packaging will neutralize the attack of environmental contaminants and will protect the steel against rust during the sea journey and storage.

Packing with wooden blocks

Bundles are placed on wooden blocks in order to leave enough space for handling by forklift.

Packing with wooden planks

Bundles are placed on wooden planks in order to ensure their straightness during transportation and facilitate the handling.
