Pittsburgh-region industrial metal includes fabrications and steel-related components with sharp edges and large free surfaces. Bags fail first by puncture, then by open store humidity. Winter cold-to-warm moves add free water if sealed too early. A global manufacturer specifies multimetal VCI film after edge protection and dry clean. Long humidity logistics still need barrier free volume and sized desiccant when design requires it.
| Step | Why it matters here | If skipped |
|---|---|---|
| 1. Dry and clean cut or machined faces | Bright metal after process | Rust under seal |
| 2. Edge protection | Fabrication corners tear film | Silent pinholes |
| 3. Multimetal wrap or bag | Closed VCI free volume | Open store corrosion |
| 4. Winter dry gate if cold move | Condensation risk | Free water sealed in |
| 5. Long humidity stack | Multi-week logistics or ocean | Film-only failure |

With VCI and desiccant when multi-week sealed logistics apply.
View Full SpecsDetroit is auto clean pack and winter sweat on tier kits. Chicago is Midwest warehouse dwell. Pittsburgh is steel-and-heavy industrial metal geometry with mill and fabrication edges.
Edge punctures on heavy fabrications, open store after cut or machine, and film-only designs on long humidity logistics.
They need edge protection and a seal that survives geometry. Chemistry is still multimetal VCI in a closed free volume.
When sealed life includes multi-week humidity exposure including ocean legs.
Grade-tied MIL-PRF-22019E and NACE TM0208 documentation where applicable, SDS, ISO certificates and a method note.
