Export packaging standards for overseas shipping of sandwich panels: 40ft High Cube and Flat-Rack container stuffing layouts, dunnage air bags, marine lashing, desiccant bags, and zero-damage protocols.
In international sandwich panel export, manufacturing excellence must be matched by bulletproof logistics engineering. Crossing thousands of ocean miles exposes freight to continuous ship roll, engine vibration, and humid tropical holds. Improperly packed containers result in scratched coatings, crushed ribs, and disastrous jobsite waste.

Frequently Asked Questions
How are long 11.8-meter panels loaded into closed dry containers? ▼
Bundles are slid smoothly using specialized hydraulic roller skid systems or long boom forklift attachments equipped with non-marking nylon guides.
Can sandwich panel container shipments exceed statutory road weight limits? ▼
Sandwich panels are volumetric cargo. Containers invariably hit 100% volumetric cube capacity long before reaching the 26-28 metric ton gross weight payload ceiling.
What protocol should be followed if transit damage occurs? ▼
The seal serial number, unsealing process, dunnage bag positions, and any damaged bundles must be photographed inside the container prior to total destuffing.
