Heavy fabrications and industrial kits around Ulsan leave yards with residue risk, sharp edges and multi-day outdoor or warehouse exposure under coastal humidity. Flash rust starts when free volume stays open or tears. A global manufacturer specifies dry clean as a hard gate, multimetal VCI film for closed free volume, edge guards where needed, VCI stretch only after bags exist, and aluminium barrier free volume with sized desiccant when multi-week ocean sealed life applies after port exit.
Busan content is Korean port gateway dwell. Ulsan stays heavy industrial clean gate and yard edge protection so Korea pages do not become doorway twins.
| Order | Action | Why |
|---|---|---|
| 1 | Remove free water and process residue | Dirty seal = rust under bag |
| 2 | Protect sharp edges that snag film | Torn free volume = open climate |
| 3 | Close multimetal free volume on critical faces | Open poly through coastal RH |
| 4 | Unitise with stretch only after free volume exists | Stretch-only heavy loads still rust |
| 5 | Add barrier free volume + desiccant when ocean weeks apply | Film-only long export stains |

With VCI and desiccant for multi-week export sealed life.
View Full SpecsBusan is Korean port gateway dwell. Ulsan is heavy industrial and shipyard-adjacent fabrication free volume with coastal humidity and later port exit when metal sails.
Process residue sealed under film, sharp edges that tear free volume, open free volume under coastal RH, and film-only multi-week ocean designs.
Yes. Residue and free water under a sealed bag accelerate damage. Dry clean is a gate.
When sealed life includes multi-week ocean humidity after Korean port exit.
Grade-tied MIL-PRF-22019E and NACE TM0208 documentation where applicable, SDS, ISO certificates and a method note covering clean gate and edge protection.
No. BENZ is a global protective packaging manufacturer.
No. Stretch unitises. Critical bare faces need closed free volume and edge protection.
Plant store plus yard days plus port dwell plus ocean weeks plus destination storage.
Share metal type, residue risk, edge geometry, yard days and export path. The reply should name clean gate, film form, edge protection and whether barrier plus desiccant are required.
