Bespoke structural enclosures

Custom Crating

Every crate is dimensioned to the millimeter. White oak battens, dadoed plywood panels, and recessed hardware form an enclosure that treats the object — not the truck — as the load-bearing system.

Vapor barrier & hygrothermal protection

Climate-Controlled Wrapping

Six-mil polyethylene vapor barrier, silica-gel desiccant packs, and humidity indicator cards seal the microclimate inside the crate — critical for transatlantic and air-freight moves.
