Ammunition chest or safe — how do I choose?

A: By the threat. Forced entry with a stated resistance time points to a safe; compartment counting and volume point to an ammunition chest. The volume gap is five times.

Can a filing cabinet replace an ammunition chest?

A: Not for standing storage. A 0.8 mm panel and one hasp resist opening, not leverage, and a 40 kg shelf will not take a full layer.

Is a site-built cabinet better value?

A: Only with a full wall and a room that will not change use. It reaches 2400 litres per square metre and is lost when the room is repurposed.

Can a box and a chest substitute for each other?

A: No. The box solves movement, the chest solves fixed storage. A box holds 50 litres and is signed off case by case.

Which measure should be fixed first?

A: Volume. Get it wrong and load, footprint and cost all move with it; get it right and the tiers narrow to two or three.

Ammunition Chest Comparison: Four Alternatives Side by Side

Quick answer: An ammunition chest competes less with other chests than with four substitutes: the mobile ammunition box, the security safe, the steel filing cabinet and the site-built cabinet. Seven measures separate them — usable volume, shelf load, protection class, locking, footprint, cost and expansion room. The chest lands upper-middle.

FAQ

1. Ammunition chest comparison: where the boundary sits

An ammunition chest is a fixed vertical cabinet, anchored to the floor, divided into compartments and locked by two people. The mobile box travels with the task, the safe is graded by door thickness, the filing cabinet is a thin-panel drawer stack, the site-built cabinet is joinery cut to the room. All five lock, but strength and volume differ by an order of magnitude.

Option	Volume	Position
Ammunition chest	300 to 900 litres	Anchored
Ammunition box	40 to 60 litres	Moves with the task
Security safe	100 to 200 litres	Fixed, heavy
Steel filing cabinet	180 to 260 litres	Semi-fixed
Site-built cabinet	1200 litres and up	Tied to the building

2. Capacity and load: five ways to hold the same stock

Shelf pitch explains most of the gap. Six shelves at 250 mm put ninety percent of a 900-litre chest to work; a four-drawer filing cabinet at 180 mm clear height uses seventy percent of 260 litres, because runners take the rest. On load, a chest shelf carries 120 kg on 1.2 mm steel with two ribs, a filing cabinet shelf 40 kg on runners that fail first, a safe shelf 80 kg behind a 10 mm door, an ammunition box 25 kg per case with no shelf.

Option	Load per shelf	Usable share
Ammunition chest	120 kg	about 90 percent
Ammunition box	25 kg per case	about 75 percent
Security safe	80 kg	about 60 percent
Steel filing cabinet	40 kg	about 70 percent
Site-built cabinet	150 kg	about 95 percent

The box loses on indivisibility, not volume. A full 50-litre case weighs 25 kg, so taking half out still means carrying all of it; a chest is drawn shelf by shelf, and pays for it when 900 litres has to be emptied before the cabinet moves.

3. Protection and locking: where the tiers split

Protection is time to entry. A safe with a 10 mm door, 6 mm body and six locking points carries a stated resistance time; a chest with a 1.2 mm door, 1.0 mm body and two points is built against casual reach, not cutting tools. Buying the wrong one for the site is the actual failure.

Locking splits the same way. The chest runs dual control — key plus padlock, both holders present. The safe runs combination plus key, one person can open it, and the log carries accountability. The filing cabinet has one hasp on 0.8 mm steel. The box uses a hasp and a numbered lead seal. The question is not whose lock is better but who is kept out.

4. Footprint and cost: two readings of one room

Read floor space as stock per square metre. A chest gives 1800 litres from 0.5 m², a filing cabinet 650 from 0.4 m², a built-in unit 2400 from a wall run to 2400 mm. Spread cost over five years and the order holds: the chest is dearer per unit and built for ten, while the filing cabinet costs forty percent less and puts a second purchase inside the window when its runners drag at three years.

5. Expansion room and conversion headroom

Expansion asks three things: can shelves be added, can dividers change, can the unit move. Chest shelf holes sit on a 250 mm grid, two more shelves go above the original six, and a re-layout takes ten minutes. A built-in unit is strongest and weakest at once — no wasted gap to 2400 mm, and scrap the moment the room changes use. Door swing is the allowance usually forgotten: 900 mm before a chest door, 450 mm of drawer pull-out.

Conclusion

The five options come down to four trades: volume against footprint, protection against cost, portability against expansion, unit price against service life. The ammunition chest sits in the middle of all four, and once the seven measures share one definition, whether an ammunition chest belongs on the site becomes arithmetic rather than opinion.
