| Bolts are packed in neutral packaging boxes, with standard quantities arranged in small cartons. The exact number of units per carton will be confirmed with the customer to align with their specific requirements. Customized packaging configurations are available upon request. | The small cartons are then consolidated into larger master cartons for secure transportation and storage. The quantity per master carton can be customized based on client specifications or aligned with standard logistical requirements. | The palletized units are securely wrapped with waterproof film and reinforced with packaging straps. Customer-specific shipping marks or labels are affixed to each pallet, ensuring clear identification and compliance with logistics requirements. This final packaging stage guarantees weather-resistant protection and stability during transportation. |
