20ft Flat Floor Bunded Store
A bunded store is what you use when the thing being stored must not reach the ground. Built from a one-trip 20ft shell, this unit has a 3 mm Durbar tread plate floor welded into the container so the base forms a sealed containment tray — if a drum splits or a valve weeps, the spill stays inside the box rather than running out under the doors.
The flat-floor configuration keeps the full internal height and gives a level surface you can wheel drums across or drive a pallet truck onto, which makes day-to-day handling considerably easier than a raised grated floor. Twenty-four vents provide the through-ventilation that stored chemicals and fuels require.
Because it starts life as a one-trip container, the shell is clean, the seals are new and the paint is unmarked — worth having on a unit that is likely to be inspected. Containment volume, ventilation and signage requirements vary by what you are storing and by state and local rules, so tell us the substance and we will confirm the specification before you order.

Choosing the Right Bunded Store
The welded 3mm Durbar bund contains spills and leaks, while 24 vents keep vapours moving, which is why flat floor units are the usual choice for drummed chemicals and oils that are moved in and out by pallet truck. If you need drainage away from the stored goods or plan to store leaking containers, compare the 20ft raised bunded store and the 20ft open mesh floor bunded store, which lift the load clear of the sump.
