Packaging and transportation
- Packaging is selected according to bar diameter, length, surface condition, and shipment method. Short bars can be bundled, while long bars are supported to reduce bending during handling.
- Surface protection is applied before packing to reduce scratches and contact damage. Export shipments are normally packed in wooden cases.
- Each package is identified with the material grade, size, heat number, and corresponding order information for traceability.
- Shipping terms and any special packing or marking requirements are confirmed before shipment.
