About the 40ft flat rack conex box
A flat rack container is a heavy steel base with end walls and no sides or roof. Cargo is loaded from the top or the sides and lashed down, which makes it ideal for loads too wide, tall, or heavy for an enclosed box.
Many flat racks have collapsible end walls that fold down for transport or stacking when empty. Strong lashing points along the deck secure machinery, vehicles, and building materials.
Why 40ft?
Twice the floor space of a 20ft unit for well under twice the price, making it the go-to choice for large inventories and conversions.
What fits
About the contents of a three- to four-bedroom home, or roughly 20 to 24 standard pallets.
Who buys a 40ft flat rack conex box?
Best for: long machinery and vehicles; boats; steel beams, pipe and timber; and oversized project cargo that has to be loaded from the top or sides.
Collapsible end walls fold down so empty flat racks can be stacked and moved more cheaply. Heavy or oversized loads may need a specialist to plan the lashing and any road permits. For shorter loads, see the 20ft flat rack.
