A 20ft new quad door shipping container — also called a 20-foot four-door conex box — is a one-trip steel unit for sale with cargo door openings on both ends and both sides for maximum access flexibility. Four full-size door sets eliminate dead corners and speed loading for logistics, staging, and high-throughput job sites.
What is a quad door container? Unlike standard double-door units, quad configuration places full cargo doors at each end plus both long sides — four independent entry points in one ISO-certified Corten steel shell. Finished in RAL 1015 Light Beige direct-to-metal paint, new units arrive pristine with a 10-year structural warranty.
Ideal for warehouse overflow, cross-dock staging, retail pop-up builds, event equipment storage, modular conversions, and job sites where crews need access from multiple sides without repositioning the container.
Best when no unloading equipment is available. The driver backs into position, tilts the trailer, and slides the container directly onto the ground.
Best when a forklift or crane is available on-site. The container must be lifted off the trailer using a forklift rated for at least 15,000 lb or an appropriate crane. Conexwest can help coordinate additional placement equipment when needed.

Containers can usually be placed directly on a solid, level surface without a foundation. Let us know in advance if the site is wet, muddy, soft, sloped, or difficult to access.
