Condition On Delivery:
It refers to the state of final plastic deformation or final heat treatment of the delivered product. The hot-rolled or cold drawn (rolled) state or manufacturing state generally delivered without heat treatment; the heat-treated state after heat treatment delivery, or the normalizing, tempering, solid solution, annealing according to the type of heat treatment status.

Delivery status	Abbreviation	Description
Cold-finished/hard (cold-finished as-drawn)	BK	No heat treatment after the last cold-forming process. The tubes therefore have only low deformability.
Cold-finished/soft (lightly cold-worked)	BKW	After the last heat treatment there is a light finishing pass (cold drawing) With proper subsequent processing, the tube can be cold-formed (e.g. bent, expanded) within certain limits.
Annealed	GBK	After the final cold-forming process the tubes are annealed in a controlled atmosphere or under vacuum.
Normalized	NBK	The tubes are annealed above the upper transformation point in a controlled atmosphere or under vacuum.

Delivery according to actual weight or delivery according to theoretical weight
Actual weight - at the time of delivery, the weight of its product is delivered according to the weighing (weighing) weight;
Theoretical weight - The weight of the product at the time of delivery is calculated from the nominal size of the steel.
