Rust Prevention for CKD Metal Components During Storage and Transit

A CKD kit that arrives with rusted burner caps or corroded panels is a hidden loss — parts you paid for that can never reach a finished stove. For local assembly operations in humid or coastal regions, corrosion control is not optional. Here is how to keep CKD metal components clean from the factory floor to your assembly bench.

Where Corrosion Creeps In

Steel and cast-iron components — burner caps, flame dividers, panels, brackets — corrode when moisture reaches bare metal. The risk peaks at three points: long sea transit inside a container, warehouse storage before assembly, and work-in-progress if parts sit exposed between stages. Each point needs its own defense.

Protective Packing at the Source

• VCI (vapor corrosion inhibitor) film — releases a protective vapor that coats metal surfaces inside sealed packaging.
• Desiccant packs — absorb residual moisture trapped in the carton.
• Oil or coating — a light protective oil on machined steel parts that is wiped off before assembly.

Storage Habits That Prevent Rust

Store kits off the floor on pallets, away from walls, in a ventilated area. Keep humidity below about 60% RH where possible, and follow first-in-first-out so no carton sits for months. Inspect incoming kits promptly and quarantine anything showing early corrosion so it does not spread.

Handle Parts Clean

Bare hands leave salts that accelerate rust — especially on machined threads like the M6x0.75 nozzle seat. Light gloves and clean workstations keep parts corrosion-free through assembly.

THREEMI Packs for the Journey

THREEMI ships gas stove CKD kits with protective packing designed for long transit, and we advise partners on storage and handling to protect their investment. Proper corrosion control means every component in the kit reaches a finished stove, not the scrap bin.
