Package
Our Package

The wires will be neatly coiled into coils according to customer requirements, or wound on wooden shafts, iron shafts or plastic drums to ensure that they are easy to pull and not easy to tangle during subsequent use.

To facilitate export, the packaging boxes will also be fumigated and marked with transportation symbols such as moisture-proof and pressure-proof.

Before shipment, the quality inspection department will make a final confirmation of the packaging firmness, label integrity and quantity accuracy, and then uniformly pack and load the cables into cabinets to ensure that the wires and cables are safely delivered to customers.
