In the case of shelving units, storage is carried out on closed shelves made of sheet steel or wood. There are perforated grids in the uprights or load-bearing side walls into which the shelf supports are hung. The shelves are either taken up by the uprights with plug connections or screwed to them.
The shelving is suitable for storing different goods in any quantity, large partial assortments with small to medium quantities that cannot be palletized (e.g. spare and standard parts) as well as for different sizes of goods (especially small parts).
