A lockable metal storage cabinet may seem like a straightforward purchase at first glance. However, models vary considerably in layout, load capacity, stability and ease of use. A cabinet suitable for light office supplies is not automatically practical for tools or heavy lever-arch files.
For home workers, offices, self-employed professionals and small businesses, three pitfalls are particularly important:
The right choice therefore starts not with the colour or marketing copy, but with how you intend to use the cabinet every day.
A steel filing cabinet or metal document cabinet is generally suitable for documents, office supplies and tools. Always check the stated load capacity per drawer or shelf. A total capacity does not indicate how much weight an individual shelf can support.
For example, the models mentioned specify:
Use these figures as product specifications, not as a general standard for all metal cabinets. Distribute heavy items evenly and place the heaviest materials as low down as possible.
Measure not only the available space, but also doorways, skirting boards and the room needed to open doors or drawers. An office storage cabinet 80 cm wide offers different possibilities from a mobile filing cabinet approximately 39 cm wide.
Think about what you will store in advance:
A cabinet with adjustable shelves is particularly useful if the contents change regularly. Fixed shelves, on the other hand, may be simpler when you only store folders or boxes of the same height.
A lockable storage cabinet helps keep documents and belongings out of sight and away from other people. Check whether keys are included and whether the lock operates on the drawers or doors. A lock is not the same as a certified anti-theft security solution.
Also consider stability. Several tall models are supplied with an anti-tip device. Attach it to a suitable wall according to the instructions. Castors are convenient on a mobile cabinet, but at least two braked castors help keep the cabinet in place.
The surroundings are also important in a garage. The product description for some models mentions a moisture- or rust-resistant surface. This is a claim made in the brand’s product information and does not guarantee that the cabinet is suitable for prolonged exposure to moisture, condensation or rain. It is therefore best to place the cabinet in a dry area.
The selection below links the product specifications to familiar usage scenarios. This helps you avoid buying a cabinet that is too small or paying for features you do not need.

Yes, a lockable cabinet can help keep documents out of sight and away from unauthorised people. However, check which type of lock is used. A standard cabinet lock provides privacy and restricted access, but does not automatically protect against burglary or fire.
Place the cabinet on a level surface, distribute the weight evenly and attach the supplied anti-tip kit to a suitable wall. Check beforehand that the wall and fixings are suitable. If in doubt, it is advisable to have the cabinet installed by a suitably qualified professional.
A metal cabinet does not use electricity. Ongoing costs are generally limited to maintenance, possible replacement keys and keeping the ventilation openings clear. On a mobile cabinet, the castors and runners may require maintenance over time, depending on the load and frequency of use.
