40 ft sea can prices
Typical asking prices as of late 2026, before delivery and tax: about $2,200–$4,800 used and $4,250–$7,000 for a one-trip high cube. Rentals usually start around $225 a month.
Will a 40 ft fit?
The container needs a pad about 42 ft × 10 ft, plus room to swing the doors open. The tilt-deck truck needs roughly 110–120 ft of straight, clear approach. If your site cannot take that, two 20s may be easier to place.
Questions
Is a 40 ft sea can twice the price of a 20?
No. A used 40 often costs only a few hundred dollars more than a used 20 from the same dealer, because 40s are the most common size in the used market. Per square foot, the 40 is the better buy.
How much does a 40 ft sea can weigh?
About 3,750 kg for a standard 40 and 3,900 kg for a high cube, empty. That matters for the delivery truck and for what is underneath it: soft ground in spring will rut.
