Shims in construction are used to compensate for height differences and to level materials. These plates are thin, often square or rectangular pieces of material that are placed under, for example, support points of structures. Here are some aspects of shims in construction

1. Thickness and Dimensions:
   Filler plates are available in different thicknesses and sizes. The choice depends on the height difference that needs to be bridged. Thick plates are used for larger height differences, while thin plates are suitable for smaller corrections.
2. Leveling:
   The main purpose of shims is to level materials. This is crucial for the stability and durability of the structure. By placing the plates under, for example, the legs of a frame, the whole can be adjusted level.
3. Versatility:
   Shims are used in various construction applications, such as laying floors, installing window frames, assembling machines, and other situations where height corrections are required.
