While stainless steel is primarily used in kitchen appliances, it can also be used for standard storage applications. There’s a lot of reason to do so; this material is very durable unlike other shelving materials like wood or plastic, and the most unfortunate thing that could happen to it is to incur minor bumps and dents. Its strength also allows it to carry heavy items with relative ease; other materials tend to bend and buckle under overwhelming weight.
Some manufacturers install locking mechanisms on the shelves, and this is particularly common with stainless steel cabinet manufacturers. The material's durability ensures that the cabinets are difficult for thieves to pry open. Similarly, this also ensures that the goods stored inside are relatively safe from household pests like rats and ants (provided that the shelves are maintained properly).
Stainless steel shelves are also relatively easy to maintain since they don’t absorb liquids like oils, paints, and thinners, which means that they are unlikely to emit an unpleasant odor. In case of a spill, the liquid can simply be wiped, and the surface can be washed with liquid soap or detergent in case the liquid left a sticky residue. The stainless steel's non-absorbent surface also prevents harmful germs and microbes from settling in, which is definitely useful when storing perishable items like food and medicine.
