| Carton Packaging | Outer Cartonbox Packaging | Pallet Packaging |
| 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. |
