Packing & labelling

The reference manual describes two standard coil packing arrangements. The packing method, labelling and marking are agreed per order.

Horizontal coil packing

Coil packed with its axis horizontal (eye-to-the-side), wrapped and secured for handling and sea transport.

Vertical coil packing

Coil packed with its axis vertical (eye-to-the-sky) on a base, wrapped and secured for transport.

  • Coil label with grade, dimensions and coil identification
  • Moisture-protective wrapping for export shipment
  • Special packing or marking requirements on request
