A 40ft new storage container w/ three 8ft roll-up doors on left side — also called a 40-foot conex box or cargo container — is a factory-fresh one-trip steel storage unit for sale with triple side access along the left long wall, giving crews three separate loading bays without sacrificing the security of a full 40-foot enclosure.

What makes a new triple-door container different? It ships with zero prior cargo cycles, so every roll-up door, seal, and panel arrives in peak condition backed by a 10-year structural warranty. Built from corrosion-resistant Corten weathering steel with an ISO-rated frame and lockable roll-up hardware, this left-side layout lets you stage inventory by bay while keeping the right wall solid for shelving or racking.

Ideal for retail distribution centers, multi-crew job sites, warehouse overflow with zone loading, fleet parts storage, and commercial yards where traffic flow favors left-side entry. Conexwest can add security lockboxes, interior shelving, custom paint, and additional door configurations to match your site plan.
