The Φ450×1300/Φ1250×1250mm 4-Hi non-reversible cold rolling mill is widely used in industries such as steel, aluminum, automotive, aerospace, and electrical appliances. It enables precise and efficient metal processing, providing high-quality products with controlled thickness, improved surface finish, and desired material properties.
Packaging:
All parts of the Φ450×1300/Φ1250×1250mm 4-Hi non-reversible cold rolling mill are fixed inside container by steel wires and special PET straps, in order to make sure all parts will not move during transportation and avoid any kinds of damage of machine and container.
Shipping:
Sea Freight: The Φ450×1300/Φ1250×1250mm 4-Hi non-reversible cold rolling mill is often shipped via ocean freight, especially for international transportation. The equipment is securely loaded into shipping containers or flat racks, which are then loaded onto cargo vessels. This mode is suitable for long-distance shipping and can accommodate larger and heavier cold rolling mill.
Air Freight: When there is a need for fast delivery or for shipping smaller or lighter cold rolling mill, air freight can be used. The equipment is packed and loaded onto aircraft for transportation. Air freight is typically more expensive than ocean freight but offers quicker transit times.
